of 0.2~12 m and being more plentiful within 3 m in the profile,include bacteria (Bacillus,Enterobacter, Escherichia, Alkaligenes, Neisseria, Staphylococcus and anaerobic bacteria such as Clostridium... and Alkaligenes. (3) The RE leached with bacteria is mainly related to the pH value of the solutions influenced by the metabolites of the bacteria; whereas that leached with fungi is mainly related......
bacteria CHAI Li-yuan, WANG Yun-yan, ZHAO Kun, SHU Yu-de (School of Metallurgical Science and Engineering, Central South University, Changsha 410083, China) Abstract: The effects of initial pH value and Ch-1 bacteria inoculation amounts on reaction rate were confirmed with the change of Cr(Ⅵ) concentration in the process of bio-reduction. Kinetic equation in each condition was established......

130021, China) Abstract: The methane oxidizing bacteria was isolated from lake bottom sediment and the corresponding DNA sequencing was carried out. Experiment of interaction between methane oxidizing bacteria-water-rock was conducted in a self-developed reactor system, and variations of the number of microorganisms and the mass concentration of HCO3- were analyzed, respectively. Finally, rock slices......
