“…For cellular fatty acid analysis, strain SK50-23 T and the two reference type strains, T. robiniae LMG 26467 T and ‘ R. boonkerdii ’ NS23, were cultivated in PY broth at 30 °C and harvested in the same logarithmic growth stage [13]. Cellular fatty acid methyl esters were prepared by heating dried cells in anhydrous methanolic HCl at 100 °C for 3 h [14], and then separated by GLC and identified using the Sherlock Microbial Identification System version 6.0.…”

A previously undescribed, heavy-metal-tolerant, motile, Gram-negative bacterium, designated strain SK50-23T, was characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SK50-23T was closely related to Tardiphaga robiniae LMG 26467T and the non-phototrophic ‘Rhodopseudomonas boonkerdii’ NS23T (98.1 and 97.3 % 16S rRNA gene sequence similarity, respectively). Strain SK50-23T possessed a circular genome of 5.86 Mb, with a DNA G+C content of 61.9 mol%. Digital DNA–DNA hybridization showed 20.8–21.6 % similarity between strain SK50-23T and related species. In addition, the whole-genome average nucleotide identity values between strain SK50-23T and related species ranged from 75.1 to 83.5 %. The major cellular fatty acid identified in strain SK50-23T was C18 : 1ω7c, and the main isoprenoid quinone present was ubiquinone Q-10. Strain SK50-23T could be assigned to the genus Tardiphaga with the species name Tardiphaga alba sp. nov. based on morphological, chemotaxonomic and genome-based taxonomic characteristics, and 16S rRNA gene-based phylogenetic characteristics. The type strain of the proposed novel species is SK50-23T (=NBRC 108825T=CGMCC No. 1.12037T).

A Gram-stain-positive, aerobic bacterium, designated as YPD9-1T, was isolated from the gut contents of a spotty belly greenling, Hexagrammos agrammus, collected near Dokdo island, South Korea. The rod-shaped cells were oxidase-positive, and catalase-negative. The major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, C16 : 0, iso-C16 : 0 and iso-C17: 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unidentified lipids. The DNA G+C content was 47.6 mol% and the predominant respiratory quinone was menaquinone MK-7. The 16S rRNA gene sequence of YPD9-1T showed low sequence similarities to species of the genus Paenibacillus, Paenibacillus pocheonensis Gsoil 1138T (97.21 % of sequence similarity), Paenibacillus aestuarii CJ25T (97.12 %) and Paenibacillus allorhizoplanae JJ-42T (96.89 %). The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that YPD9-1T formed a distinct branch among other species of the genus Paenibacillus. The digital DNA–DNA hybridisation, average nucleotide identity, and average amino acid identity values between YPD9-1T and the related species were in the ranges of 15.3–16.2 %, 74.1–78.4 %, and 71.1–71.9 %, respectively, which are below the species cutoff values. On the basis of the results of the polyphasic analysis, we conclude that strain YPD9-1T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus hexagrammi sp. nov. is proposed. The type strain of Paenibacillus hexagrammi is YPD9-1T (=KCTC 43424T =LMG 32988T).
