摘要：Background and Objective: Azo dyes were most commonly used for dyeing in the textile industry. Wastewater with high azo dyes concentration could potentially risk to environment because it was difficult to decompose naturally in the environment. Decolorization of remazol black B was investigated using wood decaying fungus strain of Ganoderma sp. and their ligninolytic enzymes. Materials and Methods: The fungus was collected from a coffee plantation in Bali, Indonesia. In this research, operating parameters affecting the color removal efficiency examined include pH, dye concentration and incubation time. Results: The results showed that the color removal of remazol black B is more effective using ligninolytic enzymes from Ganoderma sp. than directly use fungus strain of Ganoderma sp. The optimum pH condition required Ganoderma sp. to decolorize remazol black B was 6, whereas crude ligninolytic enzymes at pH 4 with dye concentration of 70 mg L¹ within 7 days incubation time. Color removal efficiency of remazol black B using the Ganoderma sp. and their crude ligninolytic enzymes was 89.23 and 90.82%, respectively. Conclusion: Ligninolytic enzyme is playing important role in degradation of dye, in which the color removal efficiency is dependent on pH, dye concentration and incubation time. The fungus strain Ganoderma and their ligninolytic enzymes have a great potential to develop as alternative technology for textile wastewater treatment.
