Inhibition of Escherichia coli Cell-Free β-Galactosidase Activity by Binary Mixtures of Water-miscible Solvents

Christian C. Opurum, Obioma K. Mejeha, Christian O. Nweke & Oluchukwu R. Nwangwu · Asian Journal of Biotechnology and Bioresource Technology · 2024

The inhibitory effects of ethanol-dimethylsulfoxide (DMSO) and ethanol-N,N-dimethylformamide (DMF) binary mixtures on the activity of cell-free β-galactosidase from Escherichia coli were assessed. The concentration-response relationships of the individual solvent and the mixtures...

Modelling of Biphasic Biogas Production Process from Mixtures of Livestock Manure Using Bi-logistic Function and Modified Gompertz Equation

Christian C. Opurum, Christian O. Nweke, Christopher E. Nwanyanwu & Nkemakolam A. Nwogu · Annual Research & Review in Biology · 2021

In this study, anaerobic digestion (AD) of three livestock manure: (poultry manure (PM), pig dung (PD), and cow dung (CD) was conducted at different mixed ratios under mesophilic (25-35°C) conditions. Two kinetic models, the modified Gompertz and bi-logistic function model were u...
