Five acetic acid bacteria isolates, awK9_3, awK9_4 (5LMG 27543), awK9_5 (5LMG 28092), awK9_6 and awK9_9, obtained during a study of micro-organisms present in traditionally produced kefir, were grouped on the basis of theirMALDI-TOFMS profile with LMG1530 and LMG1531T, two strains currently classified as members of the genus Acetobacter. Phylogenetic analysis based on nearly complete 16S rRNA gene sequences as ...
