| 1 | Contribution of phenylpropanoid metabolism to plant development and plant–environment interactions显示文摘Phenylpropanoid metabolism is one of the most important metabolisms in plants, yielding more than 8,000 metabolites contributing to plant development and plant-environment interplay.Phenylpropanoid metabolism materialized during the evolution of early freshwater algae that were initiating terrestrialization and land plants have evolved multiple branches of this pathway, which give rise to metabolites including lignin, flavonoids, lignans, phenylpropanoid esters, hydroxycinnamic acid amides, and sporopollenin.Recent studies have revealed that many factors participate in the regulation of phenylpropanoid metabolism, and modulate phenylpropanoid homeostasis when plants undergo successive developmental processes and are subjected to stressful environments. In this review, we summarize recent progress on elucidating the contribution of phenylpropanoid metabolism to the coordination of plant development and plant–environment interaction, and metabolic flux redirection among diverse metabolic routes. In addition, our review focuses on the regulation of phenylpropanoid metabolism at the transcriptional, post-transcriptional, post-translational,and epigenetic levels, and in response to phytohormones and biotic and abiotic stresses. | Nai-Qian Dong Hong-Xuan Lin | 2021 | Journal of Integrative Plant Biology2021，63，1： | 43 |
| 2 | Overview of biomass pretreatment for cellulosic ethanol production显示文摘Bioconversion of lignocellulosic biomass to ethanol is significantly hindered by the structural and chemical complexity of biomass,which makes these materials a challenge to be used as feedstocks for cellulosic ethanol production.Cellulose and hemicellulose,when hydrolyzed into their component sugars,can be converted into ethanol through well established fermentation technologies.However,sugars necessary for fermentation are trapped inside the crosslinking structure of the lignocellulose.Hence,pretreatment of biomass is always necessary to remove and/or modify the surrounding matrix of lignin and hemicellulose prior to the enzymatic hydrolysis of the polysaccharides(cellulose and hemicellulose)in the biomass.Pretreatment refers to a process that converts lignocellulosic biomass from its native form,in which it is recalcitrant to cellulase enzyme systems,into a form for which cellulose hydrolysis is much more effective.In general,pretreatment methods can be classified into three categories,including physical,chemical,and biological pretreatment.The subject of this paper emphasizes the biomass pretreatment in preparation for enzymatic hydrolysis and microbial fermentation for cellulosic ethanol production.It primarily covers the impact of biomass structural and compositional features on the pretreatment,the characteristics of different pretreatment methods,the pretreatment study status,challenges,and future research targets. | Yi Zheng Zhongli Pan Ruihong Zhang | 2009 | International Journal of Agricultural and Biological Engineering2009，2，3： | 13 |
| 3 | Lignin Interaction with Cellulase during Enzymatic Hydrolysis显示文摘The conversion of lignocellulosic biomass into biofuels or biochemicals typically involves a pretreatment process followed by the enzyme-catalyzed hydrolysis of cellulose and hemicellulose components to fermentable sugars.Many factors can contribute to the recalcitrance of biomass,e.g.,the lignin content and structure,crystallinity of cellulose,degree of fiber polymerization,and hemicellulose content,among others.However,nonproductive binding between cellulase and lignin is the factor with the greatest impact on enzymatic hydrolysis.To reduce the nonproductive adsorption of enzymes on lignin and improve the efficiency of enzymatic hydrolysis,this review comprehensively summarized the progress that has been made in understanding the interactions between lignin and enzymes.Firstly,the effects of pretreatment techniques on lignin content and enzymatic hydrolysis were reviewed.The effects of lignin content and functional groups on enzymatic hydrolysis were then summarized.Methods for the preparation and characterization of lignin films were assessed.Finally,the methods applied to characterize the interactions between lignin and cellulase were reviewed,and methods for decreasing the nonproductive binding of enzymes to lignin were discussed.This review provides an overview of the current understanding of how lignin hinders the enzymatic hydrolysis of lignocellulosic biomass,and provides a theoretical basis for the development of more economical and effective methods and additives to reduce the interaction of lignin and enzymes to improve the efficiency of enzymatic hydrolysis. | Mingfu Li Qingtong Zhang Changzhou Chen Shuangfei Wang Douyong Min | 2019 | Paper And Biomaterials2019，4，4： | 12 |
| 4 | Changes in Lignin Content and Activity of Related Enzymes in the Endocarp During the Walnut Shell Development Period显示文摘Lignification was observed using the phloroglucinol–HCl method and the content of lignin,cellulose,and polyphenol and the activity of related enzymes were measured during development with the materials of walnut of ‘Zanmei' and ‘Zhenzhuxiang'.Results showed that lignification occurred at the beginning of June,initially took shape in mid-June and finished in late July.From shell lignification to harvest,the concentrations of lignin,cellulose,and phenolic content increased before harvest,but phenolic content decreased slightly.The activities of both POD and PAL decreased and PPO varied somewhat.Correlation analysis showed lignin content to be significantly positively correlated with the cellulose content.Phenolic content had a significant positive correlation with that of lignin.Phenolic content was positively correlated with cellulose.The activity of POD had a significant negative correlation with lignin,cellulose,and phenolic content,but it was positively correlated with the activity of PAL. | ZHAO Shugang WEN Jing WANG Hongxia ZHANG Zhihua LI Xibo | 2016 | Horticultural Plant Journal2016，2，3： | 11 |
| 5 | Phosphorylation of LTF1, an MYB Transcription Factor in Populus, Acts as a Sensory Switch Regulating Lignin Biosynthesis in Wood Cells显示文摘Lignin is specifically deposited in plant secondary cell walls,and initiation of lignin biosynthesis is regulated by a variety of developmental and environmental signals.However,the mechanisms governing the regulation of lignin biosynthesis remain to be elucidated.In this study,we identified a lignin biosynthesis-associated transcription factor(LTF)from Populus,LTF1,which binds the promoter of a key lignin biosynthetic gene encoding 4-coumarate-CoA ligase(4CL).We showed that LTF1 in its unphosphorylated state functions as a regulator restraining lignin biosynthesis.When LTF1 becomes phosphorylated by PdMPK6 in response to external stimuli such as wounding,it undergoes degradation through a proteasome pathway,resulting in activation of lignification.Expression of a phosphorylation-null mutant version of LTF1 led to stable protein accumulation and persistent attenuation of lignification in wood cells.Taken together,our study reveals a mechanism whereby LTF1 phosphorylation acts as a sensory switch to regulate lignin biosynthesis in response to environmental stimuli.The discovery of novel modulators and mechanisms modifying lignin biosynthesis has important implications for improving the utilization of cell-wall biomass. | Jinshan Gui Laifu Luo Yu Zhong Jiayan Sun Toshiaki Umezawa Laigeng Li | 2019 | Molecular Plant2019，12，10： | 10 |
| 6 | Biomass-derived Porous Carbon Materials for Supercapacitor Electrodes:A Review显示文摘The development of renewable,cost-efficient,and environmentally friendly electrode materials with excellent performance is urgently needed for improving supercapacitors(SCs).Recently,biomass-derived porous carbons(BPCs)have received increasing attention due to their excellent physical and chemical properties,widespread availability,and low production cost.In this review,the progress in preparing BPCs and the properties of prepared BPCs are presented and discussed.In addition,the applications of BPCs as electrode materials for supercapacitors are also summarized.More importantly,the pore structure and surface properties of BPCs are all determining factors to improve electrochemical performance.Moreover,a high energy density and power density can be pursued by using composites based on BPCs as electrode materials,of which combining transition metallic oxide with BPCs is one of the most attractive selections.Therefore,rational design of BPCs with respect to the supercapacitor's performance should be conducted in the future. | Huimei Wang Zhong Liu Lanfeng Hui Lan Ma | 2020 | Paper And Biomaterials2020，5，2： | 10 |
| 7 | Lignocellulosic biomass as sustainable feedstock and materials for power generation and energy storage显示文摘Lignocellulosic biomass has attracted great interest in recent years for energy production due to its renewability and carbon-neutral nature.There are various ways to convert lignocellulose to gaseous,liquid and solid fuels via thermochemical,chemical or biological approaches.Typical biomass derived fuels include syngas,bio-gas,bio-oil,bioethanol and biochar,all of which could be used as fuels for furnace,engine,turbine or fuel cells.Direct biomass fuel cells mediated by various electron carriers provide a new direction of lignocellulose conversion.Various metal and non-metal based carriers have been screened for mediating the electron transfer from biomass to oxygen thus generating electricity.The power density of direct biomass fuel cells can be over 100 mW cm^(-2),which shows promise for practical applications.Lignocellulose and its isolated components,primarily cellulose and lignin,have also been paid considerable attention as sustainable carbonaceous materials for preparation of electrodes for supercapacitors,lithium-ion batteries and lithium-sulfur batteries.In this paper,we have provided a state-of-the-art review on the research progress of lignocellulosic biomass as feedstock and materials for power generation and energy storage focusing on the chemistry aspects of the processes.It was recommended that process integration should be performed to reduce the cost for thermochemical and biological conversion of lignocellulose to biofuels,while efforts should be made to increase efficiency and improve the properties for biomass fuelled fuel cells and biomass derived electrodes for energy storage. | Fangqian Wang Denghao Ouyang Ziyuan Zhou Samuel JPage Dehua Liu Xuebing Zhao | 2021 | Journal of Energy Chemistry2021，30，6： | 8 |
| 8 | Shade stress decreases stem strength of soybean through restraining lignin biosynthesis显示文摘Lodging is the most important constraint for soybean growth at seedling stage in maize-soybean relay strip intercropping system.In the field experiments,three soybean cultivars Nandou 032-4(shade susceptible cultivar; B1),Jiuyuehuang(moderately shade tolerant cultivar; B2),and Nandou 12(shade tolerant cultivar; B3) were used to evaluate the relationship between stem stress and lignin metabolism in the stem of soybean.Results showed that the intercropped soybean was in variable light condition throughout the day time and co-growth stage with maize.The xylem area and cross section ratio played a main role to form the stem stress.The B3 both in intercropping and monocropping expressed a high stem stress with higher xylem area,lignin content,and activity of enzymes(phenylalanine ammonia-lyase(PAL),4-coumarate: CoA ligase(4CL),cinnamyl alcohol dehydrogenase(CAD),and peroxidase(POD)) than those of B1 and B2.Among the soybean cultivars and planting pattern,lignin content was positively correlated with stem stress.However,a negative correlation was found between lignin content and actual rate of lodging.In conclusion,the shade tolerant soybean cultivar had larger xylem area,higher lignin content and activities of CAD,4CL,PAL,and POD than other soybean cultivars in intercropping.The lodging in maize-soybean intercropping can be minimized by planting shade tolerant and lodging resistant cultivar of soybean.The lignin content in stem could be a useful indicator for the evaluation of lodging resistance of soybean in intercropping and activities of enzymes were the key factors that influence the lignin biosynthesis. | LIU Wei-guo Sajad Hussain LIU Ting ZOU Jun-lin REN Meng-lu ZHOU Tao LIU Jiang YANG Feng YANG Wen-yu | 2019 | Journal of Integrative Agriculture2019，18，1： | 8 |
| 9 | Redox-neutral photocatalytic strategy for selective C–C bond cleavage of lignin and lignin models via PCET process显示文摘It remains challenging to achieve the selective cleavage of C–C bonds in lignin or lignin model compounds to produce aromatic products in high yield and selectivity.We have developed a redox-neutral photocatalytic strategy to accomplish this goal in both b-O-4 and b-1 lignin models at room temperature(RT)via proton-coupled electron transfer(PCET)process without any pretreatments of substrate,by adjusting the alkalinity of base to obtain a lignin models/base PCET pair with a bond dissociation free energy close to 102 kcal/mol.Without breaking down C_b–Ccbond and any C–O bonds,this PCET method is 100%atom economy and produces exclusive Ca–C_bbond cleavage products,such as benzaldehydes(up to 97%)and phenyl ethers(up to 96%),in high to excellent yields and selectivities.Preliminary studies indicated that the PCET strategy is also effective for the depolymerization of native lignin at RT,thus providing significantly important foundation to the depolymerization of lignin. | Yinling Wang Yue Liu Jianghua He Yuetao Zhang | 2019 | Science Bulletin2019，64，22： | 8 |
| 10 | Lignin biosynthesis by suppression of two O-methyl-transferases显示文摘Caffeic acid O-methyltransferase (COMT) and caffeoyl-CoA-3-O-methyltransferase (CCoAOMT) genes encode two methyltransferases at different substrate levels in lignin biosynthesis. We constructed two single antisense expression vectors containing the cDNA of COMT or CCoAOMT genes and one dual antisense expression vector containing cDNAs of both OMTs genes. The antisense constructs were transferred into tobacco mediated by Agrobac-terium tumefacience. PCR-Southern analysis indicated that antisense cDNAs had been integrated into the genome of the transgenic tobacco. The antisense genes were also expressed at transcriptional level displayed by Northern dot analysis. Klason lignin assay of 3-month-old transgenic tobaccos showed that repression in COMT or CCoAOMT alone could result in reduction of lignin content, more reduction was caused by suppression in CCoAOMT than in COMT. Furthermore, simultaneous suppression of both COMT and CCoAOMT resulted in more reduction than that of single gene, which indicated | ZHAO Huayan WEI Jianhua ZHANG Jinyu LIU Huirong WANG Tai SONG Yanru | 2002 | Chinese Science Bulletin2002，47，13： | 7 |
| 11 | Selectively transform lignin into value-added chemicals显示文摘Lignin is one of the most important biomass resources. With the increasing consumption of petroleum resource, lignin transformation is of strategic significance and has attracted widely interest. As lignin is a random construction of aromatic monomers, the degradation products are usually very complex, which limits the scaling application of lignin as feedstock for valuable chemicals. Thus, it is desperately desired to develop highly selective approach to lignin conversion. This review first gives a brief introduction to the structure of lignin, and then summarized the methods for selective transformation of lignin into phenols, aldehydes, carboxylic acids, alkanes and arenes. Finally, the challenges and opportunities of lignin selective transformation are discussed. | Qingqing Mei Xiaojun Shen Huizhen Liu Buxing Han | 2019 | Chinese Chemical Letters2019，30，1： | 7 |
| 12 | Function of the iron-binding chelator produced by Coriolus versicolor in lignin biodegradation显示文摘An ultrafiltered low-molecular-weight preparation of chelating compounds was isolated from a wood-containing culture of the white-rot basidiomycete Coriolus versicolor. This preparation could chelate Fe3+ and reduce Fe3+ to Fe2+, demonstrating that the substance may serve as a ferric chelator, oxygen-reducing agent, and redox-cycling molecule, which would include functioning as the electron transport carrier in Fenton reaction. Lignin was treated with the iron-binding chelator and the changes in structure were investigated by 1H-NMR, 13C-NMR, difference spectrum caused by ionization under alkaline conditions and nitrobenzene oxidation. The results indicated that the iron-binding chelator could destroy the β-O-4 bonds in etherified lignin units and insert phenolic hydroxyl groups. The low-molecular-weight chelator secreted by C. versicolor resulted in new phenolic substructures in the lignin polymer, making it susceptible to attack by laccase or manganese peroxidase. Thus, the synergic action of the iron-binding chelator and the lignocellulolytic enzymes made the substrate more acces- sible to degradation. | WANG Lu1, YAN WenChao1, CHEN JiaChuan2, HUANG Feng1,2 & GAO PeiJi1 1 State Key Laboratory of Microbial Technology, Shandong University, Jinan 250100, China 2 Shandong Key Lab of Pulp and Paper Engineering, Shandong Institute of Light Industry, Jinan 250100, China | 2008 | Science China(Life Sciences)2008，51，3： | 7 |
| 13 | Selective extraction and conversion of lignin in actual biomass to monophenols: A review显示文摘Our over dependency on the fossil resource for industrial chemicals and fuels faces great challenges.Recently, the production of monophenols from lignin in lignocellulosic biomass is regarded as a promising process for sustainable biofuels. This article discusses the conversion of lignin in actual biomass directly to monophenols. The two step way including extraction of lignin from biomass and further degradation of the lignin oligomers to monophenols is especially discussed. The obtained monophenols can also be converted to chemicals with low-oxygen content via hydrodeoxygenation process. For extraction of lignin,co-solvent system is the most adopted for hydrolysis or solvolysis of lignin assisted by acid or alkaline catalysts. The structure of the obtained oligomers derived from lignin is discussed in detail. For lignin depolymerization, hydrogenolysis is an efficient method with the use of gaseous hydrogen or alcohols as hydrogen source. At the meantime, depolymerization mechanism and the route for repolymerization of the reaction intermediates are presented here. In hydrodeoxygenation process, metal catalysts, especially noble metal catalysts are required. The precise effects of the reaction solvents and catalysts on extraction and degradation of lignin need to be further investigated, and this will benefit to design more efficient strategies for lignin utilization. | Zhicheng Jiang Changwei Hu | 2016 | Journal of Energy Chemistry2016，25，6： | 7 |
| 14 | Fractionational and structural characterization of lignin and its modification as biosorbents for efficient removal of chromium from wastewater:a review显示文摘The removal of chromium(Cr)from wastewater by various adsorbents has been investigated.As compared with the commercial activated carbon,the biosorbents with inexpensive and high adsorption capacities are developed from lignocellulosic wastes.Lignin,existing in lignocellulosic biomass,is the second most abundant resource in nature.Recently,lignin-based bio-sorbents were served as an advanced novel material for the metal ions and dye adsorption from wastewater.It has showed several advantages in the wastewater treatments because of the lowcost,high adsorption capacity,easy recover,and possibility of metal recovery.In this review,the isolation of lignin from lignocellulosic biomass was summarized,and the structural characteristics of lignin were comparably analyzed.The modification of lignin was performed to obtain a large surface area,strong binding-site,and high and quick adsorption properties of lignin-based adsorption materials.The adsorption efficiency of Cr ions was found to be strongly dependent on the pH of the wastewater.To further illustrate the adsorption process,the structural changes and the interactions between the metal ions and the functional groups of the lignin-based biosorbents in the adsorption process should be further investigated.Once the cost-effective and high-efficiency modification techniques are developed,lignin-based adsorbents can be expected to be the most suitable alternatives for Cr ions removal from wastewater in industry. | Bing Wang Yong-Chang Sun Run-Cang Sun | 2019 | Journal of Leather Science and Engineering2019，1，1： | 7 |
| 15 | Synthetic and lignin-based surfactants:Challenges and opportunities显示文摘Surface active agents(surfactants)are chemicals that can accumulate at the surface of a liquid,or interface between two phases with the role of changing the surface tension of the interface.Depending on their structures,they have many applications in industries,such as the petroleum,mining,pulping and textiles,wherein they are utilized as detergents,wetting agents,emulsifiers,foaming agents and dispersants.Most of commonly used surfactants are oil-based chemicals.However,using environmentally friendly feedstocks to produce surfactant is desirable to lessen the environmental impact of surfactant production and use in industry.Lignin is an attractive candidate for this purpose as it is inexpensive and readily available.Lignin and lignin derivatives,such as lignosulfonates,can be chemically modified to produce surfactants with different chemical and physical properties,which makes them suitable for a wide variety of applications.The lignin types and the processes performed for lignin production affect the properties of generated lignin significantly,which in turn influence the reactivity and the efficiency of the reaction for surfactant generation.In this review,the characteristics and applications of oil-based surfactants,and the efforts to produce lignin-based surfactants are reviewed.As oil-based surfactants with altered properties are available in the market,several different pathways can be followed for producing lignin-based surfactants.The advantages and disadvantages of using lignin-based surfactants are also discussed. | Norah Alwadani Pedram Fatehi | 2018 | Carbon Resources Conversion2018，1，2： | 6 |
| 16 | Overexpression of CmMYB15 provides chrysanthemum resistance to aphids by regulating the biosynthesis of lignin显示文摘MYB transcription factors are widely involved in the development of and physiological processes in plants.Here,we isolated the chrysanthemum R2R3-MYB family transcription factor CmMYB15,a homologous gene of AtMYB15.It was demonstrated that CmMYB15 expression was induced by aphids and that CmMYB15 could bind to AC elements,which usually exist in the promoter of lignin biosynthesis genes.Overexpression of CmMYB15 in chrysanthemum enhanced the resistance of aphids.Additionally,the content of lignin and the expression of several lignin biosynthesis genes increased.In summary,the results indicate that CmMYB15 regulates lignin biosynthesis genes that enhance the resistance of chrysanthemum to aphids. | Cong An Liping Sheng Xinping Du Yinjie Wang Yi Zhang Aiping Song Jiafu Jiang Zhiyong Guan Weimin Fang Fadi Chen Sumei Chen | 2019 | Horticulture Research2019，6，1： | 6 |
| 17 | Lignin derived hierarchical porous carbon with extremely suppressed polyselenide shuttling for high-capacity and long-cycle-life lithium-selenium batteries显示文摘Lithium-selenium(Li-Se)batteries have attracted considerable attentions for next-generation energy storage systems owing to high volumetric capacity of 3265 m Ah cm^(-3) and excellent electronic conductivity(~10^(-5)S cm^(-1))of selenium.However,the shuttling effect and capacity fading prevent their wide applications.Herein we report a low-cost strategy for scalable fabrication of lignin derived hierarchical porous carbon(LHPC)as a new high-loading Se host for high-capacity and long-term cycling Li-Se batteries in carbonate electrolyte.The resulting LHPC exhibits three-dimensional(3D)hierarchically porous structure,high specific surface area of 1696 m^(2) g^(-1),and hetero-atom doping(O,S),which can effectively confine the Se particles into the micropores,and meanwhile,offer effective chemical binding sites for selenides from hetero-atoms(O,S).As a result,our Li-Se batteries based on Se@LHPC demonstrate high capacity of 450 m Ah g^(-1) at 0.5 C after 500 cycles,with a low capacity fading rate of only 0.027%.The theoretical simulation confirmed the strong affinity of selenides on the O and S sites of LHPC effectively mitigating the Se losing.Therefore,our strategy of using lignin as the low-cost precursor of hierarchically porous carbon for high-loading Se host offers new opportunities for high-capacity and long-life Li-Se batteries. | Pengfei Lu Fangyan Liu Feng Zhou Jieqiong Qin Haodong Shi Zhong-Shuai Wu | 2021 | Journal of Energy Chemistry2021，30，4： | 5 |
| 18 | Preparation of lignin/TiO2 nanocomposites and their application in aqueous polyurethane coatings显示文摘A simple method using a water soluble lignin quaternary ammonium salt (LQAS) and TiO2 has been developed for the preparation of lignin/TiO2 nanocomposites in an aqueous medium under mild conditions. The LQAS/TiO2 nanocomposites contain well-dispersed small particles with excellent ultraviolet (UV) shielding abilities and good compatibilities with waterborne polyurethane (WPU). When the LQAS/TiO2 nanocomposites were blended with WPU, the UV absorbance and the tensile ductility of the WPU increased significantly. The composite WPU hybrid film containing 6 wt-% LQAS/TiO2 nanocomposite had the highest visible light transmittance and had excellent ultraviolet aging properties. After 192 h of UV light irradiation, the tensile strength of the composite film was above 8 MPa and the elongation at break was 800%. This work highlights new possibilities for the utilization of alkali lignin. | Dongjie Yang Shengyu Wang Ruisheng Zhong Weifeng Liu Xueqing Qiu | 2019 | Frontiers of Chemical Science and Engineering2019，13，1： | 5 |
| 19 | Preparation of nitrogen and sulfur co-doped ultrathin graphitic carbon via annealing bagasse lignin as potential electrocatalyst towards oxygen reduction reaction in alkaline and acid media显示文摘Renewable lignin used for synthesizing materials has been proven to be highly potential in specific electrochemistry.Here,we report a simple method to synthesize nitrogen and sulfur co-doped carbon nanosheets by using bagasse lignin,denoted as lignin-derived carbon(LC).By adjusting the ratio of nitrogen source and annealing temperature,we obtained the ultrathin graphitic lignin carbon(LC-4-1000)with abundant wrinkles with high surface area of 1208 m2g_1 and large pore volume of 1.40 cm3g_1.In alkaline medium,LC-4-1000 has more positive half-wave potential and nearly current density compared to commercial Pt/C for oxygen reduction reaction(ORR).More importantly,LC-4-1000 also exhibits comparable activity and superior stability for ORR in acid medium due to its high graphitic N ratio and a direct four electron pathway for ORR.This study develops a cost-effective and highly efficient method to prepare biocarbon catalyst for ORR in fuel cells. | Yixing Shen Feng Peng Yonghai Cao Jianliang Zuo Hongjuan Wang Hao Yu | 2019 | Journal of Energy Chemistry2019，28，7： | 5 |
