Cassava whey

Industrial wastes like starchy wastes cause environmental pollution especially of waterways however, they can be used for biosynthesis of enzymes (amylases) thereby reducing their pollution impact on the environment. Amylases are starch degrading enzymes that have great importance in biotechnology and starch processing industries. This study aimed at optimizing Penicillium chrysogenum biomass and amylase production in cassava whey media using organic and inorganic nitrogen supplementations. Biomass yield of P.

Whey (cassava wastewater) is an industrial residue obtained from the processing of cassava into various fermented products such as garri, fufu and lafun. Cassava whey mycoflora and their antagonistic activity against Escherichia coli were determined in this report. The associated fungi were enumerated and isolated by standard microbiological methods. The pH value of cassava whey samples was determined using an electrode pH meter while titratable acidity was by acid-base titration. Antagonistic effects of the fungal isolates against previously identified diarrheagenic E.
