Summary
The effluent from bagasse-based pulp and paper mills can be decolorized with the white-rot fungus Schizophyllum commune. The influence of pH, nutrients and aeration on the decolorizing efficiency of this fungus has been determined. It was found that it could not degrade lignin unless a more easily metabolized carbon source was made available simultaneously. The addition of carbon and nitrogen not only improved the decolorizing efficiency of the fungus, but also resulted in reduction of the biological oxygen demand (BOD) and chemical oxygen demand (COD) of effluent. A 2-day incubation period was sufficient for lignin breakdown by S. commune. The efficiency of treatment of effluent with this fungus was highest at pH 4–5 and was further improved by intermittent aeration.
