white rot fungi namely Phanerochaete chrysosporium, Phlebia floridensis,
P. radiata and P. brevispora were selected for their ligninolytic
enzymes viz., lignin peroxidase, manganese peroxidase and laccase.
Cell free enzyme extracts (as such and concentrated) obtained from these
fungi were tested for their ability to decolourise reactive red 28 (Congo
red), an industrial dye. The use of cell free enzyme extracts helped to
overcome the problem of adsorption of dye to mycelia. Laccase production was
best expressed in P. brevispora. Increase in decolourisation
percentage by concentrated culture extract was comparable to increase in
enzyme activity. P. floridensis proved to be a better dye decolouriser
in comparison to Pha. chrysosporium, thus showing its potential for
biocleaning of industrial wastes and wastewaters.
