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

Metadata-grounded summary

Citation 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.
