在厌氧条件下,微生物分解糖产生丁酸的过程称为丁酸发酵。在自然界中该过程广泛存在。例如,纤维素、半纤维素、淀粉、果胶物质及简单糖类,在不通气条件下都能进行丁酸类型的发酵。引起发酵的主要微生物是专性厌氧性的丁酸细菌(Clostridum butyricum),它生存于植物体表、土壤、污水及污泥中。

丁酸发酵是一种终产物抑制发酵,因此微生物发酵法生产丁酸收率低而经济效益差,目前尚难替代化学合成法。
Because of butyric acid fermentation inhibited by its end products, microbial fermentation is both low productive and expensive nowadays and difficult to compete with chemical synthesis.
