Decolorization of Pulp and Paper Mill Effluents Using Wood Rotting Fungus Fibrodontia sp. RCK783S

Torpong Kreetachat, Onnapha Chaisan, and Pilanee Vaithanomsat
Abstract—This work was conducted to evaluate the decolorization of pulp and paper mill effluents and the production of ligninolytic enzymes by wood rotting fungus Fibrodontia sp. RCK783S. Experimental studies were performed in growth minimal medium. As a result, Laccase activity was the main enzyme involved in decolorization of pulp and paper mill effluents. Optimization of Lac production was carried at C/N ratio 15.0 to 25.0, CuSO4 of 0.002 to 0.0004 g/L and L-asparagine of 1.563 to 2.813 g/L. It was performed by Central Composite Design (CCD). A total of 20 experiments were carried out and the Lac production of 5,145 unit/L was observed at C/N ratio of 18.0, CuSO4 0.0035 g/L and L-asparagine 2.2256 g/L. In addition, the maximum color and TOC removal efficiency were 61.58 and 48.32% at 5 days of incubation, respectively.

Index Terms—Decolorization, wood rotting fungus, pulp and paper mill wastewater, Fibrodontia sp.
