Abstract

Twelve Acetobacter pasteurianus-related strains with publicly available genomes in GenBank shared high 16S rRNA gene sequence similarity (>99.59%), but average nucleotide identity (ANI) and in silico DNA-DNA hybridization (DDH) values and multilocus sequence- and genome-based relatedness analyses suggested that they were divided into four different phylogenetic lineages. Relatedness analyses based on multilocus sequences, 1,194 core genes and whole-cell MALDI-TOF profiles supported that strains LMG 1590T and LMG 1591 (previously classified as the type strains of A. pasteurianus subsp. ascendens and paradoxus, respectively) and strain SLV-7T do not belong to A. pasteurianus. Strain SLV-7T, isolated from Korean traditional vinegar, shared low ANI (<91.0%) and in silico DDH (44.2%) values with all other Acetobacter type strains analyzed in this study, indicating that strain SLV-7T represents a new Acetobacter species. The phenotypic and chemotaxonomic analyses confirmed these results and therefore a new species named Acetobacter oryzifermentans sp. nov. is proposed with SLV-7T (=KACC 19301T=JCM 31096T) as the type strain. Strains LMG 1590T and LMG 1591 shared high ANI (99.4%) and in silico DDH (96.0%) values between them, but shared low ANI (<92.3%) and in silico DDH (<49.0%) values with other type strains analyzed in this study, indicating that strains LMG 1590T and LMG 1591 should be reclassified into a new single species that should be named Acetobacter ascendens sp. nov., comb. nov., with LMD 51.1T (=LMG 1590T=NCCB 51001T) as its type strain.
