摘要
从长期经有机磷农药污染的土壤中分离出一株能高效降解甲基异柳磷的菌株HLZ,通过生理生化试验初步鉴定为邻单胞菌属(Plesiomonas sp.)。HLZ菌株对甲基异柳磷的降解率为96%。HLZ菌株的降解谱较广,最适碳氮源分别是葡萄糖和蛋白胨,最适生长温度和pH分别是30℃,7.0,在28~35℃和pH7.4~8.6降解性能较好。
An isorenphos-methyl degrading bacterium strain designated as HLZ was isolated from soils that had long been subjected to organophosphate pollution. Strain HLZ was preliminarily identified as Plesiomonas sp. based on its biochemical-physiological characters. Strain HLZ could degrade isorenphos-methyl at a rate of 96%. The degrading spectrum of strain HLZ was broad. The optimal carbon and nitrogen sources were glucose and peptone respectively. The optimal growth temperature and pH for strain HLZ were 30 ℃ and 7.0 respectively. At the temperature of 28~35 ℃ and pH of 7.4~8. 6, strain HLZ could degrade isorenphos-methyl well.
