Abstract

Bacteria were isolated that could utilize representatives of the following ionic phosphorus-containing breakdown products of organophosphorus pesticides as sole phosphorus sources: dialkyl phosphates, dialkyl phosphorothioates, dialkyl phosphorodithioates, alkyl arylphosphonates, alkyl arylphosphonothioates, and alkyl alkylphosphonates. Utilization of each organophosphorus compound, which was complete for 7 of 12 compounds studied, was confirmed by determination of protein yield from the amount of phosphorus source consumed. This is the first report of the utilization of an ionic dialkyl thiophosphate or dithiophosphate by microorganisms.

摘要

已分离出一些细菌,它们能够利用有机磷农药的以下含离子磷的分解产物作为唯一的磷源:磷酸二烷基酯、硫代磷酸二烷基酯、二硫代磷酸二烷基酯、烷基芳基膦酸酯、烷基芳基硫代膦酸酯和烷基烷基膦酸酯。通过根据消耗的磷源量测定蛋白质产量,证实了对所研究的12种化合物中的7种有机磷化合物的利用是完全的。这是微生物利用离子型二烷基硫代磷酸酯或二硫代磷酸酯的首次报道。
