Two strains of Rhizobia isolated from sewage collected from the Chinese Baijiu distillery were characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strains W15T and W16 were grouped as a separate clade closely related to Rhizobium daejeonense L61T (98.6%). Multilocus sequence analysis (MLSA) with three housekeeping genes (recA, glnII and rpoA) also showed that strains W15T and W16 belonged to the genus Rhizobium. Average nucleotide identity and digital DNA–DNA hybridization values between genome sequences of strain W15T and the closely related species ranged from 77.0% to 87.8% and from 23.9% to 30.9%. The DNA G + C content of strain W15T was 61.6 mol%. Strain W15T contained Q-10 as the major ubiquinone and the dominant fatty acids were summed feature 8 (C 18:1ω7c and/or C 18:1ω6c; 73.1%) and C18:0 (7.6%). The main polar lipids are phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. On the basis of the evidences presented in this study, strains W15T and W16 represents a novel species of the genus Rhizobium, for which the name Rhizobium cremeum sp. nov. is proposed. The type strain is W15T (= CGMCC 1.18731T = KACC 22344T). 相似文献

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. 相似文献
