Abstract

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.
