发酵菌

The bacteriostatic effects, action mechanisms and antimicrobial spectrum of the strains were tested. After 5 days of culture, a bacteriostatic belt of 6.9-9.67 mm in width was observed on the culture plate, and the inhibitory activity maintained for 10 d. Prefiltration fermentation of the strains P1 and P5 could significantly inhibit conidial germination of the pathogen, with inhibitive rate ranging from 97.51% to 98.12%. The action might be realized by inducing hyphal deformity, bioplasm concentration, conidial germination inhibition and distorting germ tubes of conidia.

Raw fermentation is the process of liquescence, saccharification and fermentation conducting at the same time. By cutting the cook process, besides energy saving, the deoxidized sugar in the broth is in the low level during the whole process, which has the advantage of avoiding the fermenting material to be infected by other bacteria and being suitable for high gravity fermentation.

近年来兴起的生料发酵，是液化、糖化和发酵同时进行的过程，生料发酵无蒸煮工序，不仅大大降低了能耗，而且还原糖始终处于低水平，这有力避免了染菌，可以进行高浓度发酵，提高了发酵罐的生产能力。

Therefore, the ways to their separation and identification are different, except similar separation method for caproic acid bacteria and butyric acid bacteria and similar property identification method for acetic acid bacteria and lactobacillus, the other methods are quite different.

摘 要：着重研究粮食酒发酵中4类产酸菌的分离，其中己酸菌与丁酸菌同属梭状芽孢杆菌，为厌氧菌，醋酸菌为好氧菌，乳酸菌则微好氧，因此各自有不同的分离鉴定方法，其中己酸菌与丁酸菌分离方法相似，丁酸菌与乳酸菌的性能鉴定方法相似，其他则各有特色。
