Two bacteria, Bacillus sp. and Pseudomonas sp., were isolated from parathionamended flooded alluvial soil which exhibited parathion-hydrolyzing ability. Bacillus sp. readily liberated nitrite from the hydrolysis product, p-nitrophenol, but not from intact parathion. Pseudomonas sp. hydrolyzed parathion and then released nitrite from p-nitrophenol. These studies establish bacterial degradation of parathion past the p-nitrophenol stage to the end product, nitrite.
从添加对硫磷的淹水冲积土中分离出两种具有对硫磷水解能力的细菌,分别为芽孢杆菌属(Bacillus sp.)和假单胞菌属(Pseudomonas sp.)。芽孢杆菌属能轻易地从水解产物对硝基苯酚中释放出亚硝酸盐,但不能从完整的对硫磷中释放。假单胞菌属则先水解对硫磷,然后从对硝基苯酚中释放出亚硝酸盐。这些研究证实了对硫磷在细菌作用下可从对硝基苯酚阶段降解至最终产物亚硝酸盐。
