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......

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......

海泥中硫酸盐还原菌对Zn-Al-Cd牺牲阳极腐蚀的影响张杰1,刘奉令1,李伟华1,段继周1,侯保荣1(1.山东省青岛市科学院海洋研究所)摘 要:采用EIS,PC,SEM和EDS等方法,通过在硫酸盐还原菌(SRB)的一个生长周期内测试Zn-Al-Cd牺牲阳极在不含和含SRB海泥中的腐蚀行为,以对比研究海泥中SRB对其腐蚀行为的影响.EIS和PC测试结果显示,实验初期,试样在2种海泥中的腐蚀速率都快速增大,但由于SRB的大量增长,其对试样的腐蚀作用不断增强,所以在含SRB海泥中的腐蚀速率一直大于在不含SRB海泥的腐......
