Glycerol fermentation by Enterobacter agglomerans revealed that both growth and 1,3-propanediol production ceased after consumption of about 430 mM glycerol, irrespective of the initial glycerol content. This phenomenon was assigned to the production of 3-hydroxypropionaldehyde, which was identified by proton nuclear magnetic resonance and which showed a bacteriostatic effect. The accumulation during glycerol fermentation was also observed with two other enterobacterial species, i.e., Klebsiella pneumoniae and Citrobacter freundii.
聚团肠杆菌进行甘油发酵的结果表明,无论初始甘油含量如何,在消耗约430 mM甘油后,生长和1,3 - 丙二醇的产生均停止。这种现象归因于3 - 羟基丙醛的产生,通过质子核磁共振鉴定该物质具有抑菌作用。在另外两种肠杆菌,即肺炎克雷伯菌和弗氏柠檬酸杆菌的甘油发酵过程中也观察到了这种积累现象。
