Abstract:
Summary Basidiomycete PV 002, a recently isolated white-rot strain from decomposed neem waste displayed high extracellular peroxidase and rapidly decolorized azo dyes. In this study, the optimal culture conditions for efficient production of ligninolytic enzymes were determined with respect to carbon and nitrogen. An additional objective was to determine the efficiency of PV 002 to degrade the azo dyes. White-rot strain PV 002 efficiently decolorized Ranocid Fast Blue (96%) and Acid Black 210 (70%) on day 5 and 9 respectively under static conditions. The degradation of azo dyes under different conditions was strongly correlated with the ligninolytic activity. The optimum growth temperature of strain PV 002 was 26 °C and pH 7.0.
