The increasing expansion of agro-industrial activity over the last 40 years has led to the accumulation of a large quantity of lignocellulosic residues all over the world. Microbial conversion of these wastes seems to be a promising alternative for increasing their nutritional value, transforming them into animal feed and thus producing a value-added product. Candida utilis and Rhizopus oligosporus has been used in this study for the fermentation of wheat bran and rice bran for the production of single cell protein (SCP), which then can be used for animal feed as nutrition added product.
