Impact of hydraulic retention time on the production of volatile fatty acids from lignocellulosic feedstock by acidogenic fermentation

This research proposes the production and accumulation of volatile fatty acids (VFAs) through acidogenic fermentation at controlled pH 5 of olive mill solid waste. The influence of hydraulic retention time (HRT) on microbial structure the dynamics of the microbial population during the hydrolysis and acidogenesis stages was evaluated.
