摘要
作者从沿岸海域分离了３８株有机磷农药的耐药菌，用分批培养法进行富集培养，得到有机磷农药的降解菌，并着重研究了其中两株菌对甲胺磷农药的降解情况，其结果表明：在１０ｄ内，降解菌株１对甲胺磷的降解率为５９．１％，降解菌株２的降解率为 ５３．３％；在各自的甲胺磷培养液中，降解菌株１的数量大于降解菌株２；在甲胺降解过程中，其毒性逐渐减弱，降解菌株１所引起的毒性下降幅度大于降解菌株２。
Thirty-eight strains of pesticide-resisting bacteria are isolated from coastal Waters of Xiamen. These strains were cultured with organic-phosphorus pesticide to get pesticide-de composing bacteria. Intensive study have been done on the decomposing of methamidophos by two strains of bacteria. The results indicated that 59. 1 % of methamidophos was decom- posed by Strain 1 in 10d, in the same time, Strain 2 decomposed 53. 3% of methamidophos; That the value of Strain 1 in the methamidophos culture solution was larger than Strain 2, and that the toxicity of methamidophos dropped during the decomposing period.
