Anaerobic Fermentation - an overview | ScienceDirect Topics
Anaerobic fermentation is usually a slower process. In the mid-1850s, the French chemist Louis Pasteur produced anaerobiosis by boiling the medium to drive out oxygen and then introducing inert gas for cultivation. He showed that a microorganism, probably Clostridium butyricum, was responsible for butyric acid fermentation.

Anaerobic Fermentation - an overview | ScienceDirect Topics
Anaerobic Fermentation. Anaerobic fermentation products of the Stickland reaction are carboxylic acids (acetic acid, γ-aminovaleric acid, isobutyric acid, isovaleric acid, valeric acid) that can be used by crossfeeding bacteria to produce SCFA, CO2, H2 (available to the H2-using bacteria and archea), ammonia, the H-acceptor O2, or the H2 sink lactate [50].

What is Anaerobic Fermentation? (with pictures)
2022-1-29 · Anaerobic fermentation relies on enzymes to add a phosphate group to an individual adenosine diphosphate (ADP) molecule to produce ATP, which means it is a form of substrate-level phosphorylation. This contrasts with oxidative phosphorylation, which uses energy from an established proton gradient to produce ATP.
