It was found that the fermentation type was a butyricacid type fermentation.
并且确定发酵类型以“丁酸型”为主。

Because of butyricacidfermentation inhibited by its end products, microbial fermentation is both low productive and expensive nowadays and difficult to compete with chemical synthesis.
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。

After the problems in butyricacid production by microbial fermentation are analyzed, some ideas about its further development are presented.
