title: Fermentation Methods for Protein Enrichment of Cassava and Corn with Candida tropicalis.
abstract: Candida tropicalis grows on soluble starch, corn, and cassava powders without requiring that these substrates be previously hydrolyzed. C. tropicalis possesses the enzyme needed to hydrolyze starch, namely, an alpha-amylase. That property has been used to develop a fermentation process whereby C. tropicalis can be grown directly on corn or cassava powders so that the resultant mixture of biomass and residual corn or cassava contains about 20% protein, which represents a balanced diet for either animal fodder or human food. The fact that no extra enzymes are required to hydrolyze starch results in a particularly efficient way of improving the nutritional value of amylaceous products, through a single-step fermentation process.
