Identification and characterization of the dominant lactic acid bacteria isolated from traditional fermented milk in Mongolia

Abstract

Five samples of Airag and 20 of Tarag (both in Mongolia) were collected from scattered households. One hundred strains of lactic acid bacteria (LAB) were isolated and identified from these samples according to phenotypic characterization and 16S rRNA gene sequence analysis. Eighty-five isolates belonged to the genus Lactobacillus, 15 being classified as coccoid LAB. All isolates belonged to 5 genera and 11 to different species and subspecies. Lactobacillus (Lb.) helveticus was predominant population in Airag samples, Lb. fermentum and Lb. helveticus were the major LAB microflora in Tarag.

Isolation and identification of lactic acid bacteria from koumiss in Eastern Inner Mongolia of China

“…While identifying LAB from koumiss by 16S rRNA sequences, 55 strains were Lactobacillus helveticus, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus delbrueckii, Enterococcus durans, Leuconostoc lactis, Leuconost mesenteroides. Similar results were found by Sun et al [10].…”

“…and Lactobacillus helveticus were isolated in most of koumiss samples. However, we reported some different results, because we found more coccoid isolates than Sun et al (2010) in koumiss. This may be due to differences in analytical condition, pH, and production technology that shape the various microbial profiles of fermented milk.…”

Biochemical and molecular identification of lactic acid bacteria isolated from camel milk in Tunisia

“…Earlier studies reported the presence of the Lactobacillus plantarum and lactobacillus brevis in Sudanese fermented camel milk (Ashmaig et al, 2009). Sun et al (2010) isolated the Lactobacillus plantarum and Lactococcus lactis from traditional fermented milk in Mongolia.…”

Phylogenetic study of Lactobacillus acidophilus group, L. casei group and L. plantarum group based on partial hsp60, pheS and tuf gene sequences

“…A total of 234 lactobacilli were chosen from isolates (Table 1), which were preliminary classified and identified as L. casei group, L. plantarum group and L. acidophilus group by biochemical tests and 16S rRNA gene sequences in our laboratory [19][20][21][22].…”
