研究了封闭细菌培养中元素汞的命运和影响。被细菌氧化的元素汞的量从铜绿假单胞菌、荧光假单胞菌、大肠杆菌和柠檬酸杆菌的少量到枯草芽孢杆菌和巨芽孢杆菌的几乎所有添加的元素汞的量不等。系统中与细菌细胞相关的总汞的百分比从18.6到43.2%不等。两种假单胞菌的生长受到元素汞的抑制，而其他培养物的生长与无汞对照没有区别。6个培养体在48 h内均未形成甲基汞。
The fate and impact of elemental mercury in closed bacterial cultures were examined. The quantity of elemental mercury oxidized by bacteria ranged from small amounts for Pseudomonas aeruginosa, P. fluorescens, Escherichia coli, and Citrobacter to essentially all of the added elemental mercury for Bacillus subtilis and B. megaterium. The percentage of the total mercury in the system associated with bacterial cells ranged from 18.6 43.2%. Growth of the two Pseudomonas species was inhibited by elemental mercury, whereas growth of the other cultures was not distinguishable from that in mercury-free controls. No methylmercury was formed by the six cultures within 48 h.
