Continuous Decolorization of Molasses Waste Water With Mycelia of Coriolus versicolor Ps4A

Abstract

Continuous decolorization of molasses waste water by mycelia of Coriolus versicolor Ps4a was studied using waste water from a baker's yeast factory, treated by means of methane fermentation and with activated sludge. Optimum decolorization with bare pellet-type mycelia in shaking flasks needed the addition of glucose (0.5%) and peptone (0.05%) and aerobic conditions (lppm of dissolved oxygen). Continuous decolorization in a bubbling column reactor showed a decolorization yield of approximately 75% in only 20hr at a dilution rate (D) of 0.03 hr-1 under the optimum conditions. © 1985, Japan Society for Bioscience, Biotechnology, and Agrochemistry.
