Bioconversion of cassava wastes for protein enrichment using amylolytic fungi - A preliminary report

Abstract

Protein enrichment of cassava wastes using three amylolytic fungi was investigated by solid state cultivation for 6 days. Cassava waste provided the only source of carbon in the medium. Other component mineral nutrients were from (HN₄)₂ S0₄, Urea and KHP0₄. The protein contents of the wastes were improved from 2.03% (w/w) to 6.45, 9.00 and 10.50% (w/w) respectively when treated with Isaccharomyces cerevisiae, Mucor sp and Rhizopus sp. There were improvements in the protein contents to 9.76, 16.30 and 18.05% (w/w) when extra doses of nitrogenous supplements were added after 48 hours of incubation. Increases in moisture contents were equally observed with slight falls in pH values.
