Reduced crude fibre, NDF and ADF content obtained for fermented UCRM confirmed the ability of A. niger to break down fibrous constituents in cassava root reported that A. niger produces ligno-cellulolytic enzymes such as cellulases and xylanases which break down fibre and enhances fibre digestion. Reduced resistant starch and increased amylopectin content of resultant fermented product confirmed the ability of the fungus to produce enzymes capable of degrading crude starch granules for substrate enrichment
