Lignocellulosic wastes available in abundance can be excellent substrates for the production of cellulase and β‐glucosidase enzymes by solid state fermentation (SSF) . A cellulase system, showing enhanced hydrolytic potential and β‐glucosidase under SSF, was obtained by cocultivation of Aspergillus ellipticus and Aspergillus fumigatus . Different types of substrates and various pretreatments were used to improve hydrolytic process. Among the various substrates examined, sugarcane bagasse gave the highest activity and 2% calcium hydroxide treatment was found to be the most favorable treatment for the enzyme production. The maximum enzyme production was obtained on the eighth day of the fermentation process.
