    Studies on the biodegradation and utilization of selected tuber wastes by Penicillium expansum.
    (2009) AT Ajao, HJ Abdullahi, TG Atere and OM Kolawole
    Some fungi were found to be associated with the degradation of selected tuber starch wastes (Yam Peels, Cassava Peels, Sweet Potato Peels and Cocoyam Peels) of which eight showed amylase production on the Potato Dextrose Agar (PDA) supplemented with soluble starch. Penicillium expansum was selected among the isolates and used to ferment the extracts prepared from each of the tuber starch wastes for 144hours.Yam peel was found to be highly susceptible to the degradation while cocoyam peels was most resistant to the degradation. Fermentation of each of the waste extracts showed the ability of the organism to increase the protein contents, amylase activities of the waste extract with the increase in biomass. However, concentration of sugar and starch reduced considerably.
