Effect of Citric Acid Inducer on Xanthan Gum Production from Cassava Bagasse, a Potential Agro-Industry Waste

摘要

ABSTRACT In this study cassava bagasse, an agro-industrial solid-waste, was converted to xanthan gum. Glucose obtained by the acid pre-treatment of cassava bagasse was used as the substrate for the production xanthan gum. The production rate of xanthan gum was improved by the addition of citric acid. The analytical studies had shown a gradual increase in xanthan gum production when citric acid was added in fed batch mode to the fermentation media. Higher citric acid concentration was inhibitory.
