Two strains of Acetobacter sp., LTH 2460 T and LTH 2458 T , have been isolated from running red wine and cider vinegar fermentations, respectively. Taxonomic characteristics of the isolates were investigated. Comparative analysis of the 16S rRNA sequences revealed 99 % similarity between strain LTH 2460 T and the type strains of the related species Acetobacter europaeus and Acetobacter xylinus and between strain LTH 2458 T and Acetobacter pasteurianus. On the other hand, low levels of DNA

This relatedness below the species level was consistent with specific physiological characteristics permitting clear identification of these strains within established species of acetic acid bacteria. Based on these results, the names Acetobacter oboediens sp. nov. and Acetobacter pomorum sp. nov. are proposed for strains LTH 2460 T and LTH 2458 T , respectively. The phylogenetic positions of the new species are reflected by a 16S rRNA-based tree. Furthermore, a 16S rRNA-targeted oligonucleotide probe specific for A. oboediens was constructed.
