Abstract

Sixty-eight cultures of lactic acid bacteria were isolated and identified from national fermented milk drinks (airan, koumiss, kurunga, shubat) home-made in different regions of the Republic of Kazakhstan and the Buryat Republic of Russia. The cultures of lactic acid bacteria of the genus Lactobacillus were identified as L. paracasei and L. rhamnosus related to the L. casei group and as L. brevis, L. buchneri, L. diolivorans, and L. parabuchneri (the L. buchneri group) using the classical microbiological methods and on the basis of the 16S rRNA gene sequence analysis. The polymorphism of the nucleotide sequences of the genes groEL, rpoB, and rplB encoding specific proteins was studied for intraspecific differentiation of the lactobacilli. The analysis of these genes allowed a more accurate identification of the lactobacilli that are genetically and phenotypically related to the L. casei group as L. paracasei subsp. paracasei and L. paracasei subsp. tolerans. The gene nucleotide sequences of all the genotyped strains were deposited in the GenBank database.
