Gasification, microbial fermentation

Processes employed in biorefinery concepts to convert biomass feedstock into marketable products include biochemical (e.g., anaerobic digestion, microbial fermentation, enzymatic conversion), chemical (e.g., hydrolysis, transesterification, hydrogenation, oxidation), and thermochemical (e.g., pyrolysis, gasification) processes. 

Biomass is one t5rpe of carbon-neutral, renewable energy source and has been considered for an attractive resource during the past few decades due to its abundance in the world. Microbial fuel cell (MFC) is one approach to utilize the abundant biomass, and it has the advantage of directly converting biomass into electricity with high columbic efficiency over traditional biomass utilization approaches, such as incineration, gasification, fermentation, etc.
