摘要
在哈尔滨地区采集了4份长期受农药污染的土壤样品,采用稀释平板法,分离、纯化获得309株土壤真菌菌株。经鉴定,共得到21属、49种不同真菌。结果表明:90%以上真菌对甲胺磷都有一定的降解效果。伞枝犁头霉(Absidia corymbifera)、烟曲霉(Aspergillus fumigatus)、黑曲霉(A.niger)、土曲霉(A.terreus)、绿色木霉(Trichoderma viride)出现频率最高。在所有菌株中,烟曲霉原变种(A.fumigatus var.fumigatus)和密丛毛霉(Mucor plumbeus)降解率达到了60%以上,降解效果最好;绳状青霉(Penicillium funiculosum)和米根霉(Rhizopus oryzae)次之,达到了50%以上。
We separated and cultured 309 strains with four long-term pesticide-contaminated soil samples in Harbin by using dilution plate method. We identified the fungi belonging to 21 genera, 49 species. 90% of fungi have some effect on the degradation of methamidophos. Absidia corymbifera, Aspergillus fumigatus, A. terreus and Trichoderma viride are with a high frequency. In all strains, A. fumigatus var. Fumigatus and Mucor plumbeus have the degradation rate of more than 60%, followed by Penicilliumfuniculosum and Rhizopus oryzae with more than 50%.
