Cultivation of Penicillium Expansum on Rice Husk Powder for Protease Production

Penicillium expansum link was grown on 1% rice husk fine powder (40 mesh) medium and along with 1% glucose, sucrose, raffinose, maltose, molasses and cornsteep liquor for the production of protease. Production of protease was found to be higher in the rice husk mineral medium and rice husk incorporated with cornsteep liquor as compared to other media. Pure sugars used as carbon and energy sources promoted the growth of Penicillium expansum to varying degrees in comparison to protease production.
