Decolourisation of synthetic textile dyes by Phlebia tremellosa

Abstract

Phlebia tremellosa decolorised eight synthetic textile dyes (200 mg l-1) by greater than 96% within 14 days under stationary incubation conditions. High performance liq. chromatog. anal. of culture supernatants indicated that Remazol Black B was degraded by the fungus, however, complete mineralization did not occur as a colorless org. breakdown product accumulated. Laccase activity was detectable in culture supernatants after 5 days when the fungus was grown in the presence of an artificial textile effluent, with activity reaching a max. of 15 U l-1 on day 14.
