Single and cooperative bioleaching of sphalerite by two kinds of bacteria--Acidithiobacillus ferriooxidans and Acidithiobacillus thiooxidans XIA Le-xian(夏乐先), LIU Jian-she(柳建设), XIAO Li(肖 利... is higher than that in pure culture and the sterile control. In these processes, two kinds of bacteria perform different functions and play a cooperative role during leaching of sphalerite......
; 文献标志码:A 文章编号:1672-7207(2010)01-0015-06 Bioleaching of chalcopyrite by moderately thermophilic mixed microorganisms in stirred tank.... Chalcopyrite concentrate was leached by moderately thermophilic mixed microorganisms, including Acidithiobacillus caldus, Leptospirillum ferriphilum, Sulfobacillus acidophilus, Sulfobacillus......

method has been developed to reflect the growth of bacteria CH-1 via the potential of the solution. The results indicate that during the bacterial cultivation, the biomass increases and the potential... be divided into two segments. The growth of bacteria CH-1 is different under various experimental conditions, but the biomass is directly related to the potential of the solution regardless......
献标志码:A 文章编号:1672-7207(2013)05-1754-06 Iron reduction of hematite by dissimilatory iron-reducing bacteria FENG Yali1, WANG Lijuan1, 2, LI Haoran2, ZHANG... by dissimilatory iron-reducing bacteria (DIRB). Using ferric hydroxide as the electron acceptor and sodium acetate as the electron donor, dissimilatory iron-reducing bacteria was isolated from anaerobic......
. With computer simulating variation of ferrous ion concentration during the bacteria growth, this model can be used to determine the kinetic parameters of bacteria growth, and the influence of these parameters on bacteria growth can be predicted. Under the varied experimental conditions of initial ferrous ion concentration, temperature and inoculation amount, the ferrous ion concentration......
High level arsenic resistance in bacteria present in biooxidation tanks used to treat gold-bearing arsenopyrite concentrates: A review D. E. RAWLINGS Department of Microbiology... was slow and inefficient, partly because the bacteria were sensitive to the high concentrations of arsenic that were released. Arsenic inhibition was so severe that after a period of aeration, the mineral......
