Decolorization of alcohol distillery wastewater by thermotolerant white-rot fungi.
To detect thermotolerant fungus strain for decolorization of alcohol distillery wastewater (WAD), 38 fungus strains were studied. Ability of ligninolytic enzyme production was examined at 35 and 43 degrees C on agar media containing 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) and MnCl2. At 43 degrees C, four of Pycnoporus coccineus strains showed their higher potential for WAD decolorization both on agar media and in liquid media. Immobilized mycelia on polyurethane foam removed total phenol about threefold higher than free mycelia did in shaking condition at 43 degrees C. Moreover, color removed by immobilized mycelia nearly 50% higher than free mycelia did.
