Butanediol fermentation test
WebButanediol fermentation is typical for the facultative anaerobes Klebsiella and Enterobacter [1] and is tested for using the Voges–Proskauer (VP) test. There are other alternative strains that can be used, talked about in details in the Alternative Bacteria Strains section below. Figure 2: The fermentation process to produce butanediol WebAug 22, 2024 · Butyric acid fermentation is characteristic of several obligate anaerobic bacteria that mainly belong to the genus Clostridium. Pyruvate is in turn oxidized to acetyl-CoA, with the production of CO 2 and H 2. Part of the acetyl-CoA is converted into acetic acid, with ATP production.
