摘　　要：通过对产酸发酵细菌细胞内生物物理化学及发酵途径分析表明，控制生物产酸发酵类型的主要因素有ＮＡＤＨ／ＮＡＤ＋平衡和发酵产物酸性末端数量。根据微生物的生理生态学原理及试验结果分析，证实所发现的乙醇型发酵优于丁酸型发酵和丙酸型发酵。此外，还对氢分压与丙酸积累的相关性提出新的见解。The physical chemistry in the cell of acidogenic fermentation bacterium and the fermentation path wereanalysed.It made known that the primary factors of controlling acidogenic fermentation type were the NADH /NAD+ balanceand the amount of acid- group of products. According to the principle of physiological ecology and the test results,it wasverifled that the ethanol type fermentation was better than the butyric acid type fermentation and the propionic acid typefermentation. In addition,a new idea for the correlation of hydrogen pressure with the accumulation of propionic acid was put forward.
