Abstract:

采用常规、含Cd2+和含Pb2+的马丁氏培养基,对云南省会泽县废弃铅锌矿区和非矿区中华山蓼(OxyriasinensisHemsle)根际真菌进行分离,将分离的菌株接种到含不同浓度(0、0.05、0.5和5mmol·L-1)Cd2+的马铃薯葡萄糖培养液中,研究和比较了废弃铅锌矿区和非矿区中华山蓼根际真菌的镉耐性。结果表明,Cd2+显著抑制铅锌矿区和非矿区中华山蓼根际真菌的生长;Cd2+对常规、含Cd2+和含Pb2+的马丁氏培养基分离的铅锌矿区中华山蓼根际真菌的EC50平均值和最大值均明显大于非矿区,表明铅锌矿区中华山蓼根际真菌对Cd2+的耐性强于非矿区,采用含Cd2+培养基,从铅锌矿区中华山蓼根际分离出的真菌Cd2+耐性最强。
