乳杆菌的细胞形态多样,常见以短杆状、长杆状和球杆状成链排列生长。在显微镜下观察到乳杆菌大多数无运动,只有极少数具有周身鞭毛的才运动,并且它无芽孢,革兰氏染色为阳性。它对生长条件要求苛刻必须提供氨基酸、盐类、脂肪酸类以及可发酵碳水化合物等才能生长。常见的乳杆菌属有:乳酸杆菌属、运动杆菌属、真细菌属、假枝杆菌属和链条杆菌属“依据其菌属发酵产物的不同可分为(1)同型乳酸发酵乳酸杆菌。(2兼氧性异型乳酸发酵乳酸杆菌。(3)专性异型乳酸发酵乳酸杆菌

The cell morphology of Lactobacillus is various, and it grows in short rod, long rod and ball rod in chains. Under the microscope, most lactobacilli did not move, only a few with flagella around the body moved, and it had no spores, gram-positive staining. It has strict requirements for growth conditions. It must provide amino acids, salts, fatty acids and fermentable carbohydrates to grow. The common lactobacilli are: lactobacilli, sports bacilli, eubacteria, pseudomycobacterium and Streptobacillus. According to the different fermentation products of lactobacilli, they can be divided into (1) homotype lactobacilli. (2) facultative heterotypic Lactobacillus. (3) Lactobacillus fermentans with specific heterotypic lactic acid<br>
