| physiological function | the specific activities of ADH, formate benzyl viologen oxidoreductase, and hydrogenase dramatically increase in cells grown under sulfur limitation. This is accompanied by increased amounts of H2 and alcohol (ethanol and butanol). Under S0 limitation, ADH may reduce to alcohols the aldehydes that are generated by fermentation, thereby serving to dispose of excess reductant | Thermococcus paralvinellae |
