mer操纵子。本研究的目的是分离能在含500ppm HgCl2的培养基营养琼脂(NA)上生长的耐汞细菌，并分析其在营养肉汤(NB)培养基中对HgCl 的还原能力。在含10ppm HgCl2的营养琼脂上用平板法分离细菌。用试剂盒Microgen TM GnA + B-ID System进行细菌鉴定，用CV-AAS 测定细菌的降汞能力; (Cold Vapour Atomic Absorption Spectrophotometer). Result showed, that the bacteria found in this research were Bacillus sp and Aeromonas hydrophila. Both of these bacteria were able to reduce HgCl2 in the amount of 98,7% for Bacillus sp and 98,33% for Aeromonas hydrophila. In the future those bacteria can be use as bioremediation agent.
