Inhibition on Acidogenesis of Dairy Wastewater by Zinc and Copper

Environmental Technology (United Kingdom), 2001
Acidogenesis of dairy wastewater produced volatile fatty acids, mainly acetate and propionate, plus hydrogen as by-product. Zinc (Zn) inhibited acidogenesis at concentrations over 10 mg l(-1); but at 10 mg l(-1), or less, it enhanced acidogenesis slightly.

Anaerobic fermentation of cattle manure: Modeling of hydrolysis and acidogenesis

Water Research, 2007
A mathematical model for the hydrolysis and acidogenesis reactions in anaerobic digestion of cattle manure is presented. This model is based on the premise that particulate hydrolysable fraction of cattle manure is composed of cellulose and hemicellulose that are hydrolyzed at different rates according to a surface-limiting reaction; and, that the ...

Thermodynamic analysis of product formation in mesophilic acidogenesis of lactose

Biotechnology and Bioengineering, 2004
AbstractThermodynamic analysis on the acidogenesis of lactose was performed to evaluate the different acidogenic patterns and mechanisms by using Gibbs free energy calculation. Batch acidogenesis of lactose was investigated by using an enriched culture at 37°C, pH 5.5 and varied substrate levels.
