2,3-Butanediol fermentation is anaerobic fermentation of glucose with 2,3-butanediol as one of the end products. The overall stoichiometry of the reaction is

2 pyruvate + NADH --> 2CO₂ + 2,3-butanediol.

Butanediol fermentation is typical for Klebsiella and Enterobacter and is tested for using the Voges–Proskauer (VP) test.

The metabolic function of 2,3-butanediol is not known.

Comparison with mixed acid fermentation

2,3-butanediol fermentation produces smaller amounts of acid than mixed acid fermentation, and butanediol, ethanol, CO₂ and H₂ are the end products. While equal amounts of CO₂ and H₂ are created during mixed acid fermentation, butanediol fermentation produces more than twice the amount of CO₂ because the gases are not produced only by formate hydrogen lyase like they are in the mixed acid fermentation
