Lactobacillus plajomi sp. nov. and Lactobacillus modestisalitolerans sp. nov., isolated from traditional fermented foods in Thailand (original) (raw)

International journal of systematic and evolutionary microbiology, 2015

Abstract

Three strains of Lactobacillus, NB53T, NB446T, and NB702 were isolated from traditional fermented food in Thailand. Comparative 16S rRNA gene sequence analysis indicated that these strains belong to the Lactobacillus plantarum group. Phylogenetic analysis based on the dnaK, rpoA, pheS, and recA gene sequences indicated that these three strains were distantly related to known species present in the Lactobacillus plantarum group. DNA-DNA hybridization with closely related strains demonstrated that these strains represented two novel species; these strains were differentiated based on chemotaxonomical and phenotypic characteristics. Therefore, two novel Lactobacillus species, Lactobacillus plajomi sp. nov. (NB53T) and Lactobacillus modestisalitolerans sp. nov. (NB446T and NB702), are proposed with the type strains NB53T (= NBRC 107333T = BCC 38054T) and NB446T (= NBRC 107235T = BCC 38191T), respectively.
