Isolation and screening of bacterial isolates for degradation of recalcitrant industrial waste dyes

Abstract

This study was aimed to screen recalcitrant industrial waste dyed degrading ability of Bacteria isolated from the soil and sludge samples collected from Yavatmal region of Maharashtra State of India. The strains were isolated for their ability to degrade dyes like Congo red, Indigo blue dyes, which are difficult to degrade, hazardous, and carcinogenic. The Bacterial isolates are suppose to produce enzymes like, Peroxidase, and Laccase which play important role in degradation of recalcitrant dyes by oxidation. Further the isolates were characterised based on their utilization of sugar. In this study the Bacterial isolates RS1and BH1 which have good dye degradation ability was successfully isolated and characterized.
