使用碱作为储存介质的防腐剂的方法显然特别适用于产生酸的发酵。用发酵中使用的培养物对储存的培养基进行消毒的程序，其中部分发酵的培养基的酸度充当其自身的防腐剂，是实现相同目的的另一种可能的方法。然而，对于许多发酵，必须连续或间歇地对原料培养基进行灭菌。为了防止发酵培养基被产生不稳定物质的微生物污染，通常可以通过适当控制H-离子浓度来防止。在这方面必须记住，产酸生物的生长通常受到所产生的酸的未离解形式的抑制，其浓度是H-离子浓度和酸总浓度的函数（1）。
The method of using alkali as a preservative for medium in storage is obviously particularly applicable to fermentations producing acid. The procedure of inoculating the medium in storage with the culture used in the fermentation, whereby the acidity of the partially fermented medium acts as its own preservative, is another possible means of ac-complishing the same purpose. For many fermentations, however, it would be necessary to sterilize raw medium either continuously or intermittently. The prevention of contamination of the fermenting medium with organisms producing undesirablesubstances mayfrequently be prevented by proper control of H-ion concentration. It must be remembered in this connection that the growth of acid-producing organisms is usually inhibited by the undissociated form of theacid produced, the concentration of which is a function of both the H-ion concentration and the total con-centration of the acid (1).
