The aim of this work was to study the influence of pH and temperature on acidogenic
fermentation and bio-hydrogen production. A centered factorial design was generated with …

Acidogenic fermentation is a technology able to produce hydrogen and volatile fatty acids in
friendly environmental way. Because of that, it is important to improve the knowledge in this …

The objective of this study was to evaluate the production of hydrogen in a two-stage CSTR
system–both reactors having the same volume–and compare its performance with a …

Acidogenic fermentation is an anaerobic process of double purpose, while treating organic
residues it produces chemical compounds, such as hydrogen, ethanol and organic acids …

Batch experiments were carried out to study the roles of pH in the biologic production of
hydrogen and volatile fatty acids from glucose by enriched anaerobic cultures. The results …

Hydrogen is considered a very clean energy source, since its combustion releases mainly
water as a reaction product. Besides, it has the advantage of having the highest energy …

Hydrogen was produced by an ethanol–acetate fermentation at pH of 5.0±0.2 and HRT of 3
days. The yield of hydrogen was 100–200mlgGlu− 1 with a hydrogen content of 25–40 …

Hydrogen production from food waste by the mesophilic and thermophilic acidogenic culture
acclimated with food waste at 5 days HRT for the effect of pH and volatile solid (VS) …

The purpose of this work was to study the acclimatization of activated sludge as it evolved
into an acidogenic culture capable of producing volatile fatty acids and hydrogen from …

Hydrogen fermentation using glucose as a single substrate caused abrupt pH drops and the
gradual losses of hydrogen producers, which in turn led to system failure. In this study the …
