Amylase Production from Aspergillus sp Isolated from Dumpsite Soil Using Corn-Cob and Orange-mesocarp as a Substrate

Williams, K. F, CHIOMA, D.M, Opara, C & Kingsley, R.S · Microbiology Research Journal International · 2026

The increasing demand for sustainable and cost-effective enzyme production has driven research toward microbial fermentation using agro-residues as substrates. This study investigated dumpsite soils as reservoirs of α-amylase–producing fungi and evaluated corn cob and orange meso...

Open access Research Article 10.9734/mrji/2026/v36i21712

Production of Exopolysaccharides by Bacteria Isolated from River Water Using Banana and Yam Peels as Substrates

Williams, K. F, CHIOMA, D.M, Opara, C & Dan, J.I · South Asian Journal of Research in Microbiology · 2025

The rising interest in microbial exopolysaccharides (EPS) has prompted the search for cost-effective substrates and efficient bacterial strains to enhance production. This study investigated river water as a source of EPS-producing bacteria and evaluated banana and yam peels as p...
