Decolorization of methyl orange with live and autoclaved
biomass fungi were studied. Sixteen different fungi
including Fusarium, Trichoderma, Humicola,
Aspergillus, Penicillium, Paecilomyces,
Alternaria and Beauveria were evaluated. The
highest decolorization activity was observed with
Fusarium acuminatum and Humicola fuscoatra.
Decolorization efficiencies of live and autoclaved biomasses
were compared. In addition, spores of eight fungi showing
high decolorization efficiency were inoculated for
decolorization ability. The most successful fungi were
Penicillium sp. and Fusarium sp. For adsorption
studies, methyl orange decolorization with live and
autoclaved biomasses were found most suitable with malt
extract compared to yeast extract peptone medium.
