The effects of some added carbohydrates on cellulases and ligninase and decomposition of whole bagasse

Abstract

Two basidiomycetes mould isolates were studied for the production of extracellular cellulases and ligninase in submerged shake culture using whole bagasse as substrate. The effects of some added carbohydrates on enzyme production, substrate decomposition and biomass formation were examined. In both cultures the addition of lactose stimulated biomass production and increased the decomposition of total carbohydrate and lignin contents of bagasse. Lactose was the only sugar which stimulated cellulase and ligninase in both cultures.
