oxygen-free habitat for microbial

Anaerobic catabolism of an organic compound in which the compound servs as both an electron donor and an electron acceptor and in which ATP is usually produced by substrate-lvl phosphorylation

An enzyme, widely distributed in anaerobic microorganisms, capable of oxidizing or evolving H₂

producing only lactic acid from the fermentation of glucose

producing a mixtur of products, typically lactate, ethanol, plus CO₂ , from the fermentation of glucose

the key enzyme of glycolysis. present in homofermentative lactic acid bacteria

• characteristic of enteric bacteria,
• 3 different acids are forms: acetic, lactic, and succinic
• also formed: Ethanol, CO_{2 ,} & H₂
