what type of gas is produced during fermentation?
hydrogen gas ( h )
fermentation reacts nadh with an endogenous, organic electron acceptor. usually this is pyruvate formed from sugar through glycolysis. the reaction produces nad+ and an organic product, typical examples being ethanol, lactic acid, carbon dioxide, and hydrogen gas (h). however, more exotic compounds can be produced by fermentation, such as butyric acid and acetone. fermentation products contain chemical energy (they are not fully oxidized), but are considered waste products, since they cannot be metabolized further without the use of oxygen.
fermentation
hydrogen gas is produced in many types of fermentation (mixed acid fermentation, butyric acid fermentation, caproate fermentation, butanol fermentation, glyoxylate fermentation) as a way to regenerate nad from nadh. electrons are transferred to ferredoxin, which in turn is oxidized by hydrogenase, producing h. hydrogen gas is a substrate for methanogens and sulfate reducers, which keep the concentration of hydrogen low and favor the production of such an energy-rich compound, but hydrogen gas at a fairly high concentration can nevertheless be formed, as in flatus.
