Biodegradation of Turquoise Blue Textile Dye by Wood Degrading Local Fungi Isolated from a Plantation Area

Abstract

This research aimed to investigate the potential screening of wood degrading fungi to degrade the textile dye. Nine fungi were selected based on their ability to remove the turquoise blue textile dye on liquid potatoes dextrose médium. The fungi which have a high color removal efficiency were identified and analyzed qualitatively in terms of the manganese peroxidase and lignin peroxidase enzymes and their enzyme activity was determined. The selected fungi were investigated for their ability to degrade turquoise blue under variations in pH, dye concentration, and contact time. The results showed that three of the nine strains of wood-degrading local fungi, identified as Trametes hirsuta, Microporus xanthopus, and Ganoderma applanatum, were able to degrade textile dye. The color removal efficiency of dye treatment was monitored under the initial pH, dye concentration, and contact time variation. The study analyzed that the optimal color removal efficiency of the turquoise blue textile dye with a concentration of 30 mg/L in an aqueous solution was achieved at 78.50 and 85.84% at pH 6 for Microporus xanthopus and Ganoderma applanatum, while the color removal efficiency was 82.17% at pH 5 for Trametes hirsuta with seven days of incubation time
