Candidate Selection for Fungi Growing Media in Dye Waste Degradation

Abstract

Exploration of microorganisms such as bacteria and fungi this decade increases significantly to studied and developed because it is potentiality. However, fungi have more potential than bacteria because fungi produce ligninolytic extracellular enzymes such as lignin peroxidase, manganese peroxidase and laccase which play an important role in the degradation process of organic compounds such as dyestuff waste. This study will examine the potential of Pleurotuscystidiosus fungi in degrading textile dyes direct congo red (DCR) using different growing media. The stages include the ratio of fungi to growing media and the concentration of dyes that can be degraded at variations in dye concentrations of 150 mg-1 ppm, 200 mg L-1, 250 mg L-1, and 300 mg L-1. The results showed a ratio of 3% (b/b) in rice husk media with a degraded DCR concentration of 269 mg L-1 and 9% (b/b) in sawdust media with a degraded DCR concentration of 298 mg L-1. The result shows that sawdust media is better in degrading DCR with degradation efficiency of 94%.
