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......

Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China Central South University Press and Springer-Verlag Berlin Heidelberg 2016 Abstract: The disinfected bacteria will be a photoreactivation under the irradiation of the sunlight, and the light intensity plays an important role in the bacteria resurrection. The effect of light intensity on photoreactivation of Escherichia coli (E. coli......
was studied. After leaching for 29 days, the leaching ratio of zinc was 91%. Three kinds of bacteria, mixture-based bacteria, 9K-based bacteria and sulfur-based bacteria were used in marmatite leaching, of which the mixture-based bacteria have the best leaching result while the sulfur-based bacteria have the worst. By analyzing the leaching residue using SEM and EDXA, the marmatite leaching mechanism......

The effects of different... standard of waste water. Key words: sulfate-reducing bacteria (SRB); crosslinking agent; wastewater containing zinc ......
in free bacteria. The variation of whole bacterial community was significantly associated with solution pH, total iron, and ferric iron concentrations. Pearson correlation analysis and partial least square path model both indicated that attached bacteria made larger contribution to the copper extraction of tailings. Key words: fine-grained tailings; column bioleaching; heap construction method; free......
