Electro‐fermentation triggering population selection in mixed‐culture glycerol fermentation
Electro-fermentation is a new technique that could be used to influence the global metabolism in mixed-culture fermentation. In this study, a mixed-culture cathodic electro-fermentation of glycerol was investigated. Both microbial community structure and metabolic patterns were altered when compared to standard fermentation. This microbial population shift was more significant when the working ...
متن کاملConsistent 1,3-propanediol production from glycerol in mixed culture fermentation over a wide range of pH
BACKGROUND Glycerol is currently an over-produced chemical that can be used as substrate for the production of high value products such as 1,3-propanediol (1,3-PDO) in fermentation processes. The aim of this study was to investigate the effect of initial pH on a batch mixed culture fermentation of glycerol, considering both the bacterial community composition and the fermentation patterns. RE...
متن کاملInfluence of Escherichia coli hydrogenases on hydrogen fermentation from glycerol
Since the actual role of Escherichia coli hydrogenases on fermentation from glycerol has not been clear, we evaluated the effect of inactivation of each E. coli hydrogenase on cell growth, hydrogen production, organic acids production, and ethanol production. Inactivation of hydrogenase 2 and hydrogenase 3 reduced cell growth, hydrogen and succinate production as well as glycerol utilization wh...
متن کاملEnhanced hydrogen and 1,3-propanediol production from glycerol by fermentation using mixed cultures.
The conversion of glycerol into high value products, such as hydrogen gas and 1,3-propanediol (PD), was examined using anaerobic fermentation with heat-treated mixed cultures. Glycerol fermentation produced 0.28 mol-H(2)/mol-glycerol (72 mL-H(2)/g-COD) and 0.69 mol-PD/mol-glycerol. Glucose fermentation using the same mixed cultures produced more hydrogen gas (1.06 mol-H(2)/mol-glucose) but no P...
