Enhancement of corn stover conversion to carboxylates by extrusion and biotic triggers in solid-state fermentation.

Solid-state fermentation is a potential technology for developing lignocellulosic biomass-based biorefineries. This work dealt with solid-state fermentation for carboxylates production from corn stover, as building blocks for a lignocellulosic feedstock-based biorefinery. The effect of extrusion pretreatment, together with the action of a microbial consortia and hydrolytic enzymes as biotic triggers, was investigated on corn stover conversion, microbial metabolic pathways, and populations.

Biohydrogen production from food waste: Current status, limitations, and future perspectives.

Among the various biological routes for H production, dark fermentation is considered the most practically applicable owing to its capability to degrade organic wastes and high H production rate. Food waste (FW) has high carbohydrate content and easily hydrolysable in nature, exhibiting higher H production potential than that of other organic wastes. In this review article, first, the current status of H production from FW by dark fermentation and the strategies applied for enhanced performance are briefly summarized.

Microbial ecology of fermentative hydrogen producing bioprocesses: useful insights for driving the ecosystem function.

One of the most important biotechnological challenges is to develop environment friendly technologies to produce new sources of energy. Microbial production of biohydrogen through dark fermentation, by conversion of residual biomass, is an attractive solution for short-term development of bioH2 producing processes. Efficient biohydrogen production relies on complex mixed communities working in tight interaction.
