Bioaccumulation and detoxification of trivalent arsenic by Achromobacter xylosoxidans BHW-15 and electrochemical detection of its transformation efficiency.

砷营养细菌可通过将高毒性的三价砷[As(III)]氧化为低毒、低生物累积的五价砷[As(V)]降低砷污染。本研究以从砷污染管井水中分离的亚砷酸盐氧化菌 Achromobacter xylosoxidans BHW-15 为对象，系统评价其砷耐受、细胞内砷积累、固定化转化及电化学检测能力。该菌最低抑制浓度（MIC）为15 mM As(...
