| 1 | Enrichment, isolation and identification of sulfur-oxidizing bacteria from sulfide removing bioreactor显示文摘Sulfur-oxidizing bacteria (SOB) are the main microorganisms that participate in the natural sulfur cycle. To obtain SOBwith high sulfur-oxidizing ability under aerobic or anaerobic conditions, aerobic and anaerobic enrichmentswere carried out. Denaturing gradient gel electrophoresis (DGGE) profiles showed that the microbial community changed according to the thiosulfate utilizationduring enrichments, and Rhodopseudomonas and Halothiobacilluswere the predominant bacteria in anaerobic enrichment and aerobic enrichment, respectively,which mainly contributed to the thiosulfate oxidization in the enrichments. Based on the enriched cultures, six isolateswere isolated from the aerobic enrichment and four isolateswere obtained from the anaerobic enrichment. Phylogenetic analysis suggested the 16S rRNA gene of isolates belonged to the genus Acinetobacter, Rhodopseudomonas, Pseudomonas, Halothiobacillus,0chrobactrum, Paracoccus, Thiobacillus, and Alcaligenes, respectively. The tests suggested isolates related to Halothiobacillus and Rhodopseudomonas had the highest thiosulfate oxidizing ability under aerobic or anaerobic conditions, respectively; Paracoccus and Alcaligenes could aerobically and anaerobically oxidize thiosulfate. Based on the DGGE and thiosulfate oxidizing ability analysis, Rhodopseudomonas and Halothiobacilluswere found to be the main SOB in the sulfide-removing reactor, andwere responsible for the sulfur-oxidizing in the treatment system. | Jianfei Luo Guoliang Tian Weitie Lin | 2013 | Journal of Environmental Sciences2013，25，7： | 10 |
| 2 | Heme Oxygenase-1 is Associated with Wheat Salinity Acclimation by Modulating Reactive Oxygen Species Homeostasis显示文摘Heme oxygenase-1 (HO-1) has been recently identified as an endogenous signaling system in animals. In this study, HO-1 upregulation and its role in acquired salt tolerance (salinity acclimation) were investigated in wheat plants. We discovered that pretreatment with a low concentration of NaCl (25 mmol/L) not only led to the induction of HO-1 protein and gene expression, as well as enhanced HO activity, but also to a salinity acclimatory response thereafter. The effect is specific for HO-1, since the potent HO-1 inhibitor zinc protoporphyrin IX blocks the above cytoprotective actions, and the cytotoxic responses conferred by 200 mmol/L NaCl are reversed partially when HO-1 inducer hemin is added. Heme oxygenase catalytic product, carbon monoxide (CO) aqueous solution pretreatment, mimicked the salinity acclimatory responses. Meanwhile, the CO-triggered re-establishment of reactive oxygen species (ROS) homeostasis was mainly guaranteed by the induction of total and isozymatic activities, or corresponding transcripts of superoxide dismutase, ascorbate peroxidase, and cytosolic peroxidase (POD), as well as the downregulation of NADPH oxidase expression and cell-wall POD activity. A requirement of hydrogen peroxide homeostasis for HO-1-mediated salinity acclimation was also discovered. Taken together, the above results suggest that the upregulation of HO-1 expression was responsible for the observed salinity acclimation through the regulation of ROS homeostasis. | Yanjie Xie Weiti Cui Xingxing Yuan Wenbiao Shen Qing Yang | 2011 | Journal of Integrative Plant Biology2011，53，8： | 2 |

| 12 | Oxidation process of lanthanum hexaboride ceramics显示文摘Oxidation process of lanthanum hexaboride (LaB6) ceramic powder was investigated . The LaB6 powder samples were heated continually from room temperature to 1 473 K at a heating rate of 10 K/min by differential scanning calorimetry. The oxidation tests were conducted at different exposure temperatures. The phases and morphologies of the samples before and after exposure were analyzed by XRD and SEM. It was pointed out that before 1 273 K, LaB6 has high oxidation resistant ability, which was due to that the oxide layer hinders the oxygen diffusion from outer to the surface of LaB6 grains. The oxide layer was composed of the transition phases, which were composed of La2O3 and B2O3 formed from the initial oxidation; when the oxidation temperature exceeded 1 273 K, protective layer was destroyed due to the vaporization of liquid B2O3. Based on the results of X-ray diffraction analysis, oxidation process of LaB6 ceramic powder can be described as follows: Before 1 273 K, lanthanum borate,La(BO2)3 was formed on the surface of samples, then lanthanum oxide (La2O3) and boron oxide (B2O3) were present on the surface of samples oxidized when the temperature reached to 1 473 K. | ZHENG Shuqi, MIN Guanghui, ZOU Zengda , YU Huashun, HAN Jiande , and WANG Weiti School of Materials Science and Engineering, Shandong University, Jinan 250061, China | 2002 | Rare Metals2002，21，2： | 0 |
