汞是环境中的重金属污染物之一，对生物具有毒性。瓦坡街道的金矿利用汞提取黄金，并将废物随意排放到环境中。几项有先例的研究结果表明，金加工废液中含有抗汞细菌。耐汞细菌可以作为生物修复剂，因为这些细菌可以减少汞。耐汞菌质粒中含有mer操纵子。本研究的目的是分离出能在含有500 ppm HgCl₂的培养基营养琼脂(NA)上生长的抗汞细菌，并分析其在营养肉汤(NB)培养基中对HgCl₂的还原能力。采用平板法在含有10 ppm HgCl₂的营养琼脂上进行细菌分离。采用kit Microgen TM GnA + B-ID系统进行细菌鉴定，采用cv - aas法测定细菌对汞的还原能力; (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.
