重金属污染已成为全球严重的环境问题,从受污染的环境中分离出抗重金属的微生物已经成为一个热点。以河池市南丹县矿山的重金属污染土壤作为研究对象,从中筛选到一株耐Cu2＋浓度达到30 mmol/L的根霉属菌株;一株耐Pb2＋浓度为8 mmol/L的曲霉属菌株;一株耐Sn2＋浓度为30 mmol/L的酵母属菌株,为利用微生物治理重金属污染提供候选菌株资源,同时对微生物修复的应用具有一定的指导意义。

The pollution of heavy metals has become a serious global environmental problem. It' s a hot issue to isolate the tolerant microganism from the contaminated environment. In this paper three tolerant strains are isolated from the mine soil of Nandan county in Hechi region, which contain a Rhizopus strain that can resist 30 mmoL/L Cu2+ ; a Aspergitlus strain that can resist 8 mmoL/L Pb2+ ; and a Saccharomyces strain that can resist 30 mmol/L Sn2+. The result of the research can provide candidate strain resources for using microorganism to remediate heavy metal pollution and also provide references for the application of microbial remediation.
