酸马奶酒中微生物的分离鉴定及抗菌特性的研究

Isolation, Identification and Anti-Bacteria Function of Microorganisms From Koumiss

从内蒙古锡盟不同地区采集 15份酸马奶酒样品 ,经分离纯化、归属种鉴定 ,并单菌发酵液经调 p H值、蒸发酒精、浓缩后 ,对李斯特杆菌、金黄色葡萄球菌、大肠杆菌进行抑菌研究。结果表明 ,酸马奶酒是由多种乳酸菌和酵母菌共同发酵的乳饮料。其中乳酸菌中有球菌 5个属 ,杆菌 6个属 ,酵母菌 6个属。乳酸菌中有 9株乳球菌和 12株乳杆菌对李斯特杆菌有抑制作用 ,对大肠杆菌和金黄色葡萄球菌无抑制作用。酵母菌中有 4株对大肠杆菌有抑菌作用 ,其中有 2株同时对金黄色葡萄球菌有抑制作用 。

The koumiss is a kind of fermented milk drink by multi microorganisms. Microorganisms are isolated from 15 koumiss samples of pastoral area in Xilin Guole. According to the morphological characteristics and biochemical reacton and sugar fermentation characteristics, they respectively belonged to Lactococcus 5 genus, Lactobacillus 6 genus, yeasts 6 genus. It is also found that some microorganisms have inhibitory effect on the growth of Listeria, S. aureus and E. coli . Nine strains of Lactococcus and 12 strains of Lactobacillus have the inhibitory effect on Listeria, but do not have the inhibitory effect on E. coli and S. aureus. Four strains of yeasts have the inhibitory effect on E. coli, two strains of them have the inhibitory effect of S. aureus, meanwhile , but do not have the inhibitory effect on the Listeria.
