Phenol Metabolism by White Rot Fungus Phanerochaete chrysosporium Isolated from Indian Paper Mill Effluent Enriched Soil Samples

P.C. Prabu and C. Udayasoorian

Abstract

The white rot fungus Phanerochaete chrysosporium isolated from paper mill effluent enriched soil samples degrading various phenol (Mono, di hydroxy and methoxy) compounds. During five days of incubation period, 74% of para-hydroxy benzoic acid was utilized by the isolated Phanerochaete chrysosporium when glucose used as a co-substrate. There was 57% degradation of protocatechuic acid using fructose. The fungus degraded vanillin in the presence of co-substrates and the response was more in glucose and fructose than starch. The presence of laccase (EC.1.10.3.2) and polyphenol oxidase (EC.1.10.3.0) extracellular activity suggested that the microorganism secrete these enzymes into the extracellular medium.
