Abstract
Pseudomonas aeruginosa CW961, an isolate from the vicinity of a deep-sea hydrothermal vent, grew in the presence of 5 mM Cd(2+) and removed Cd(2+) from solution. Sulfate was sufficient for growth when Cd(2+) was not present in the culture medium; however, thiosulfate was necessary for Cd(2+) precipitation and cell survival in the presence of Cd(2+).
摘要
铜绿假单胞菌CW961是从深海热液喷口附近分离出来的菌株，能在5 mM Cd(2+)存在的情况下生长，并从溶液中去除Cd(2+)。当培养基中不存在Cd(2+)时，硫酸盐足以支持其生长；然而，在Cd(2+)存在的情况下，硫代硫酸盐对于Cd(2+)沉淀和细胞存活是必需的。
