Statistical Correlation between Ligninolytic Enzymes Secretion and Remazol Brilliant Yellow‐3GL Dye Degradation Potential of Trametes versicolor IBL‐04

Abstract

Trametes versicolor IBL‐04 was used for biodegradation of Remazol Brilliant Yellow 3‐GL (RBY3‐GL) reactive textile dye in Kirk's basal salts medium. During the initial screening study, the maximum decolorization (93.5%) of RBY3‐GL was achieved in 7 days' shaking incubation period at pH 4 and 30 °C. Different physical and nutritional factors were statistically optimized to enhance the efficiency of T. versicolor IBL‐04 for maximum decolorization. Under optimal conditions T. versicolor IBL‐04 completely decolorized (100%) the RBY3‐GL in 2 days of incubation with negligible adsorption on fungal mycelia. Laccase was the major enzyme (938.3 U/mL) secreted by T. versicolor IBL‐04 along with comparatively lower activities of MnP. In this article and for the first time, a statistical correlation has been successfully investigated between the ligninolytic enzymes from an indigenously isolated white rot fungi, T. versicolor IBL‐04, and the degradation of RBY3‐GL.
