Dark-fermentative hydrogen production from synthetic lignocellulose hydrolysate by a mixed bacterial culture: The relationship between hydraulic retention time and pH conditions.

This study assessed the effect of hydraulic retention time (HRT) ranging from 24 to 3 h on continuous dark-fermentative H production in four bioreactors operated at pH 5.0, 5.5, 6.

Direct Fermentative Hydrogen Production from Cellulose and Starch with Mesophilic Bacterial Consortia.

Hydrogen produced from lignocellulose biomass is deemed as a promising fuel of the future. However, direct cellulose utilization remains an issue due to the low hydrogen yields. In this study, the long-term effect of inoculum (anaerobic sludge) heat pretreatment on hydrogen production from untreated cellulose and starch was evaluated during repeated batch processes.
