title: Decolourisation of diverse industrial dyes by some Phlebia spp. and their comparison with Phanerochaete chrysosporium.
abstract: Three species of Phlebia, viz. P. brevispora, P. fascicularia and P. floridensis have been evaluated for their potential to decolourise eight industrial dyes including; reactive yellow, reactive orange, reactive red, rathidol scarlet, coracryl black, coracryl pink, coracryl violet and coracryl red. The cultures used for the present study were pre adapted by growing these on yeast glucose agar medium supplemented with Poly-R 478, a reference dye. The fungal cultures were grown in mineral salts broth and harvested after different incubation periods to obtain their cell free enzyme extracts which were then used to assess their ability to decolourise the above mentioned dyes. The extracts obtained from the cultures grown for six days significantly decolourised the tested dyes. The study revealed Phlebia spp. to be better dye decolourisers than Phanerochaete chrysosporium.
