The dynamic of cellulase activity of fungi inhabiting organic municipal solid waste.

ABSTRACT

The study dealt with to identified and screened out potential cellulase producing fungal strains. All the indigenous fungal strains were developed on carboxymethyl cellulose (CMC) mandel media at 30 °C for 3-4 days to examine their congo red cellulase activity. It was found from the primary screening test result that only four isolates Trichoderma viride, Aspergillus niger, Aspergillus fumigatus and Fusarium oxysporum were shown large zone formation that meant they have great potential cellulase activity. Among these, Trichoderma viride and Aspergillus niger strains were showed highest enzymatic activity during the secondary screening, while Trichoderma viride generated the highest protein (89.51 µg/ml). Furthermore, these potential fungal strains will be useful for the organic municipal solid waste degradation.
