| 1 | Plant Growth-Promoting Traits in Rhizobacteria of Heavy Metal-Resistant Plants and Their Effects on Brassica nigra Seed Germination显示文摘Phytoremediation is an emerging technology that uses plants and their associated microbes to clean up pollutants from the soil, water, and air. In order to select the plant growth-promoting rhizobacteria(PGPR) for phytoremediation of heavy metal contamination, 60 bacterial strains were isolated from the rhizosphere of two endemic plants, Prosopis laevigata and Spharealcea angustifolia, in a heavy metal-contaminated zone in Mexico. These rhizobacterial strains were characterized for the growth at different pH and salinity, extracellular enzyme production, solubilization of phosphate, heavy metal resistance, and plant growth-promoting(PGP) traits, including production of siderophores and indol-3-acetic acid(IAA). Overall, the obtained rhizobacteria presented multiple PGP traits. These rhizobacteria were also resistant to high levels of heavy metals(including As as a metalloid)(up to 480 mmol L(-1)As(V), 24 mmol L(-1)Pb(Ⅱ), 21 mmol L(-1)Cu(Ⅱ), and 4.5 mmol L(-1)Zn(Ⅱ)). Seven rhizobacterial strains with the best PGP traits were identified as members of Alcaligenes, Bacillus, Curtobacterium, and Microbacterium, and were selected for further bioassay.The inoculation of Brassica nigra seeds with Microbacterium sp. CE3R2, Microbacterium sp. NE1R5, Curtobacterium sp. NM1R1,and Microbacterium sp. NM3E9 facilitated the root development; they significantly improved the B. nigra seed germination and root growth in the presence of heavy metals such as 2.2 mmol L(-1)Zn(Ⅱ). The rhizobacterial strains isolated in the present study had the potential to be used as efficient bioinoculants in phytorremediation of soils contaminated with multiple heavy metals. | Brenda ROMN-PONCE Diana Miryel REZA-VZQUEZ Sonia GUTIRREZ-PAREDES María de Jesús DE HARO-CRUZ Jessica MALDONADO-HERNNDEZ Yanely BAHENA-OSORIO Paulina ESTRADA-DE LOS SANTOS En Tao WANG María Soledad VSQUEZ-MURRIETA | 2017 | Pedosphere2017，27，3： | 4 |
| 2 | Supplementation of a lacto-fermented rapeseed-seaweed blend promotes gut microbial-and gut immune-modulation in weaner piglets显示文摘Background:The direct use of medical zinc oxide in feed will be abandoned after 2022 in Europe,leaving an urgent need for substitutes to prevent post-weaning disorders.Results:This study investigated the effect of using rapeseed-seaweed blend(rapeseed meal added two brown macroalgae species Ascophylum nodosum and Saccharina latissima)fermented by lactobacilli(FRS)as feed ingredients in piglet weaning.From d 28 of life to d 85,the piglets were fed one of three different feeding regimens(n=230 each)with inclusion of 0%,2.5% and 5% FRS.In this period,no significant difference of piglet performance was found among the three groups.From a subset of piglets(n=10 from each treatment),blood samples for hematology,biochemistry and immunoglobulin analysis,colon digesta for microbiome analysis,and jejunum and colon tissues for histopathological analyses were collected.The piglets fed with 2.5% FRS manifested alleviated intraepithelial and stromal lymphocytes infiltration in the gut,enhanced colon mucosa barrier relative to the 0% FRS group.The colon microbiota composition was determined using V3 and V1-V8 region 16S rRNA gene amplicon sequencing by Illumina NextSeq and Oxford Nanopore MinION,respectively.The two amplicon sequencing strategies showed high consistency between the detected bacteria.Both sequencing strategies indicated that inclusion of FRS reshaped the colon microbiome of weaned piglets with increased Shannon diversity.Prevotella stercorea was verified by both methods to be more abundant in the piglets supplied with FRS feed,and its abundance was positively correlated with colonic mucosa thickness but negatively correlated with blood concentrations of leucocytes and IgG.Conclusions:FRS supplementation relieved the gut lymphocyte infiltration of the weaned piglets,improved the colon mucosa barrier with altered microbiota composition.Increasing the dietary inclusion of FRS from 2.5% to 5% did not lead to further improvements. | Yan Hui Paulina Tamez-Hidalgo Tomasz Cieplak Gizaw Dabessa Satessa Witold Kot Søren Kjærulff Mette Olaf Nielsen Dennis Sandris Nielsen Lukasz Krych | 2022 | Journal of Animal Science and Biotechnology2022，13，1： | 1 |
