Abstract

Flavobacterium sp. ATCC 27551 hydrolysed both diethyl (parathion and diazinon) and dimethyl (methyl parathion and fenitrothion) phosphorothioates while Pseudomonas sp. ATCC 29353 hydrolysed only diethyl (parathion and diazinon) phosphorothioates. Glucose inhibited the hydrolysis of parathion by Pseudomonas sp., but not by Flavobacterium sp. Evidently, the Flavobacterium hydrolase differs from that of Pseudomonas sp. The Pseudomonas sp. converted 4-nitrophenol to 4-aminophenol in the presence of glucose and to nitrite in its absence; 4-nitrophenol was not metabolized by the Flavobacterium sp.
