Title
Degradation of 4-aminophenol by newly isolated Pseudomonas sp. strain ST-4
Abstract

Aromatic compounds and their substituted forms are hazardous to the environment. Biodegradation by microorganisms can be used to remove these pollutants from soil and water. During the present investigations, Pseudomonas sp. strain ST-4 was used for the degradation of 4-aminophenol. The strain was able to use 4-aminophenol as growth substrate showing growth up to 400 ppm on mineral salt media plates. In broth, degradation up to 84% was observed. Induction with 4-aminophenol proved to be effective as it increased the degradation rate more than by the uninduced cell. Biodegradation was found to be more effective than autoxidation of 4-aminophenol, indicating bioremediation as main process to eliminate aromatic amines. In order to locate the responsible genes for degradation, curing and then isolation of plasmid showed the involvement of plasmid encoded genes in this mechanism since the cured strains do not grow with 4-aminophenol.
