The high yield of propionic acid in mixed acid fermentation was the main reason for the low hydrogen production capacity.
混合酸发酵的发酵产物中丙酸含量较高是产氢能力偏低的主要原因。

An coupling bioprocess for in situ propionic acid recovery coupled with fermentation of vitamin B12 was established based on this technology.
将此工艺用于发酵过程中丙酸的原位吸附分离，建立了维生素b12发酵与丙酸在线分离的耦合过程。
