Abstract

Fourteen homofermentative lactic acid bacteria that were isolated from kefir grains and kefir fermented milks were assigned to either or , based on their characteristic morphotypes, phenotypic features and SDS-PAGE profiles of whole-cell proteins. Further genotypic analyses on representative strains from both taxa demonstrated that and share 100 % 16S rDNA sequence similarity and belong phylogenetically to the species group. DNA–DNA binding values of >79 % and analogous DNA G+C contents of 37–38 mol% showed that the strains studied belonged to one species: is a later synonym of . An emended description is proposed for . Due to the specific morphological and biochemical characteristics of these taxa in kefir grain formation, it is proposed that should be reclassified as subsp. subsp. nov.
