摘要
从采集自蒙古国戈壁地区的6份自然发酵乳中分离到14株乳酸菌,经过形态特征,生理生化特性,糖发酵试验和乳酸旋光性的测定,鉴定结果:乳酸球菌5株,包括Lactococcus lactissubsp.cremoris 1株,Pedio-coccus.(后缩写为Ped.).urinaeequi3株,Pediococcus.pentosaceus1株;乳杆菌9株,包括Lactobacillus.(后缩写为L.)helveticus8株,Lactobacillus.delbrueckii.subsp.bulgaricus1株。蒙古国戈壁地区自然发酵乳中的优势菌为Lactobacillus.helveticus,其次为Pediococcus.urinaeequi。
Fourteen strains of lacto-bacteria were isolated from six samples collected from naturally fermented milk in Gobi region in Mongolia and identified as Lactococcus lactis subsp, cremoris (1 strain), Pediococcus urinaeequi (3 strains), Pediococcus pentosaceus ( 1 strain), 9 strains of Lactobacillus, including L. helveticus ( 8 strains) , and L. delbrueckii subsp, bulgaricus ( 1 strain). The dominant strains in naturally fermented milk in Mongolian Gobi region are Lactobacillus helveticus, followed by Pediococcus urinaeequi.
