We examined the role of microorganisms in the degradation of the organophosphorus (OP) insecticide chlorpyrifos (CP) during kimchi fermentation. During the fermentation of kimchi, 30 mg L(-1) of CP was added and its stability assayed during fermentation. CP was degraded rapidly until day 3 (83.3%) and degraded completely by day 9. Four CP-degrading lactic acid bacteria (LAB) were isolated from kimchi fermentation in the presence of 200 mg L(-1) CP and were identified as Leuconostoc mesenteroides WCP907, Lactobacillus brevis WCP902, Lactobacillus plantarum WCP931, and Lactobacillus sakei WCP904. CP could be utilized by these four strains as the sole source of carbon and phosphorus. Coumaphos (CM), diazinon (DZ), parathion (PT), and methylparathion (MPT) were also degraded by WCP907, WCP902, WCP931, and WCP904 when provided as sole sources of carbon and phosphorus.
我们研究了微生物在泡菜发酵过程中对有机磷（OP）杀虫剂毒死蜱（CP）降解的作用。在泡菜发酵过程中，添加了 30mg/L 的 CP，并在发酵过程中检测其稳定性。CP 迅速降解，直到第 3 天（83.3%），到第 9 天完全降解。从含有 200mg/L CP 的泡菜发酵中分离出 4 株 CP 降解乳酸菌（LAB），并鉴定为肠膜明串珠菌 WCP907、短乳杆菌 WCP902、植物乳杆菌 WCP931 和清酒乳杆菌 WCP904。这四种菌株可以将 CP 作为唯一的碳源和磷源加以利用。在提供唯一的碳源和磷源的情况下，WCP907、WCP902、WCP931 和 WCP904 还能降解敌百虫（CM）、敌敌畏（DZ）、对硫磷（PT）和甲基对硫磷（MPT）。
