    摘要: Members of the Acetobacter pasteurianus are popular acetic acid bacteria (AAB) for the production of vinegar. Neither phenotypic nor the most frequently applied genotypic marker (16S ribosomal DNA) provides sufficient resolution for accurate identification of the AAB strains. In this study, the gyrB gene was used for species discrimination by direct DNA sequencing and as marker in a species-specific PCR assay. All examined A. pasteurianus strains were clearly distinguished from the closely related species by comparative sequence analysis of the gyrB gene. The average sequence similarity for the gyrB gene (82.2 %) among type strains was significantly lower than that of the 16S rRNA sequence (98.2 %). Therefore, the gyrB gene can be proposed as an additional molecular marker for A. pasteurianus and related taxa that provides higher resolution than 16S rRNA. In addition, the species-specific primers were also developed based on the gyrB and 16S rRNA gene sequences, which were then employed for PCR using the template DNA of Acetobacter strains. The PCR primer pairs were shown to be specific for A. pasteurianus, A. peroxydans and papayae. Our data indicate that the phylogenetic relationships in the A. pasteurianus group are easily resolved by direct sequencing of the gyrB gene and combined with species-specific PCR assays.
