Acidogenesis driven by hydrogen partial pressure towards bioethanol production through fatty acids reduction

摘要: H2 partial pressure drives the reduction of carboxylic acid (short chain fatty acids) formed as primary metabolites in acidogenic fermentation to form bioalcohols. Microbial catalysis under influence was evaluated comparison with a reactor operated at atmospheric identical conditions. Carboxylic gets regulated selectively by elevated pressures and redox conditions, resulting formation alcohols. The non-equilibrium intra extracellular ions causes anaerobic bacteria alter their pathways function interspecies transfer. Ethanol production quantified, acetic major synthesised during acidogenesis. influenced electrochemical activity which reflected distinct variation electron transfer rates catalytic mediators (NAD+/NADH, flavoproteins iron-sulphur clusters). bioprocess depicted this communication non-genetic regulation product formation, understanding metabolism alternate route for alcohol production.
