本项研究从科尔沁草原的阿鲁科尔沁牧区南北4个苏木16个牧户中采集43个乳样。从43个乳样中分离到64株乳酸菌，对其中的47株进行了鉴定，结果分离到29株乳杆菌属的细菌。对其中10株进行了种的鉴定，结果4株为犊牛乳杆菌(Lactobacillusvitulinus)、2株德氏乳杆菌(L.delbrueckii)、2株植物乳杆菌(L.plantarum)、1株瘤胃乳杆菌(L.ruminis)、1株清酒乳杆菌(L.sake)共为5个种。本项研究发现，该牧区自然发酵酸乳中主要菌株是乳杆菌属细菌和肠球菌属细菌的乳酸菌菌株，这些菌均属于中温发酵性菌株，经对其生物学特性的鉴定基本符合乳杆菌属、种的鉴定标准。

64 strains of lactic acid bacteria were isolated from 43 samplesof milk and milk products collected from Arhorgin pasture.Among them,47 strains of lactic acid bacteria were identifiod in genus.29 strains belonged to lactobacillaceae.10 strains of them were further identified in species.They respectively belonged to L.vitulinus(4 strains)、L.delbrueckii(2 strains)、L.plantarum(2 strains)、L.ruminis(1 strain) and L.sake(1 strain).The results also revealed that the natual fermented yoghurt in this area is related with lactobacillaceae and Enterococcus.They were medium-tempeture strains.On the whole,the strains tested had the same biological properties in comparison with standerd genus and species.
