Abstract
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 to 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.
摘要
研究了密闭细菌培养体系中元素汞的归宿和影响。被细菌氧化的元素汞量各不相同，从铜绿假单胞菌、荧光假单胞菌、大肠杆菌和柠檬酸杆菌氧化少量元素汞，到枯草芽孢杆菌和巨大芽孢杆菌氧化几乎所有添加的元素汞。系统中与细菌细胞结合的总汞百分比在18.6%至43.2%之间。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中的生长没有区别。这六种培养物在48小时内均未形成甲基汞。
