The methane fermentation of carbohydrates

WebThe methane yield from glycerol trioleate after dark hydrogen fermentation increased by 81.9% to 946.5 mL/g-TVS after 0.8 g-O-3/g-TVS pretreatment. When food waste (carbohydrate 45.7%, protein 21.4%, lipid 28.1%) and glycerol trioleate were mixed with a total volatile solids (TVS) ratio of 1:1, an ozonation pretreatment of 0.02 g-O-3/g-TVS gave ... WebAnaerobic metabolism (fermentation) yields VFA, carbon dioxide, and energy (ATP) for growth of the fermenting organism. Basically, this is a three phase operation: Phase 1 Complex carbohydrates are degraded to simple sugars by microbial extracellular enzymes. These are simple molecules, the components of the original polymers.
