查询词典 microorganisms

The soil microorganisms quantities, microbial diversity index, microbial biomass carbon and the cellulose decomposition strength significantly reduced with increasing of heavy metal concentration, but the soil basal respiration rate were positively enhanced.

该矿区土壤微生物区系组成和微生物活性显著不同于临近非矿区土壤，随着重金属含量的增加，土壤微生物数量、微生物多样性指数、微生物生物量碳以及纤维素分解强度均显著降低，但土壤基础呼吸却明显升高；土壤脲酶、碱性磷酸酶、多酚氧化酶对铅锌矿较为敏感，而蔗糖酶和过氧化氢酶受到的抑制作用不明显。

The microorganisms was domesticated by adding a certain amount of lead in the soil, and three lead-tolerant strains including Pb-R-1, Pb-R-2 and Pb-H-3 accordingly originating from 300 mg/L, 750 mg/L and 900 mg/L lead medium were isolated with a series of PDA medium of different lead concentrations. Through the identification, Pb-R-2 was confirmed as Aspergillus sp., Pb-R-3 as Penicillium sp. The trials of transferring culture showed that all strains had the stable heredity of lead tolerance in different composition PDA medium.
