摘要:

研究新疆酸马乳中乳酸乳球菌WLB5、干酪乳杆菌MLS5与马克思克鲁维酵母菌WWMJ1间的相互作用。结果表明:在酸马乳发酵过程中,马克思克鲁维酵母菌WWMJ1可以促进干酪乳杆菌MLS5的生长,干酪乳杆菌MLS5对马克思克鲁维酵母菌WWMJ1的生长有抑制作用,乳酸乳球菌WLB5能促进马克思克鲁维酵母菌WWMJ1的生长。乳酸乳球菌WLB5和干酪乳杆菌MLS5混合发酵有助于提高酸马乳中乳酸菌总活菌数。本研究可为酵母菌在发酵乳制品中的应用及开发新型乳制品提供一定参考。

Abstract:

Two lactic acid bacteria (LAB) strains and one yeast strain, previously isolated from traditional fermented
koumiss in Xinjiang, were inoculated into pasteurized mare’s milk in both single and co-cultures to study their growth and
interactions. The LAB strains consisted of Lactobacillus casei MLS5 and Lactococcus lactis WLB5. The yeast strain used
was Kluyveromyces marxianus. The results showed that the growth of Lactobacillus casei MLS5 during fermentation was
significantly promoted by Kluyveromyces marxianus. K. marxianus was significantly inhibited by Lactobacillus casei MLS5,
but was significantly enhanced by Lactococcus lactis WLB5. The viable LAB count of the co-culture of Lactobacillus casei
MLS5 with Lactococcus lactis WLB5 in koumiss was increased when compared with that of the single cultures. The results
of this study can provide useful references to apply yeasts in fermented dairy products and develop new dairy products.

Key words: koumiss, lactic acid bacteria, yeast, interaction
