Emended Description

A novel Gram-staining-negative, facultatively anaerobic, motile and rod-shaped bacterium, designated strain LHW37T, was isolated from a dead ark clam collected on the south coast of Korea. The novel strain grew optimally at 37 °C, at pH 7.0–8.0 and with 2 % (w/v) NaCl. The predominant cellular fatty acids were C18 : 1ω7c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The major isoprenoid quinone was ubiquinone-8 (Q-8) and the predominant polar lipids were phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain was most closely related to Neptunomonas japonica JAMM 0745T (97.1 % sequence similarity). The genomic DNA G+C content of strain LHW37T was 48.2 mol%. The DNA–DNA relatedness values recorded in hybridization experiments between the novel strain and its closest known relative were ≤18 %. Based on the phenotypic, genotypic and phylogenetic data, strain LHW37T represents a novel species belonging to the genus Neptunomonas for which the name Neptunomonas concharum sp. nov. is proposed. The type strain is LHW37T ( = KACC 15543T  = JCM 17730T). An emended description of the genus Neptunomonas is also provided.

Cymbidium Goeringii

Two Gram-staining-negative, aerobic, non-spore-forming rod-shaped, non-motile bacteria, designated strains R156-2T and T58-2 were isolated from the roots of Cymbidium goeringii. The colonies were yellow-pigmented. On the basis of 16S rRNA gene sequence similarity, strains R156-2T and T58-2 were shown to be members of the genus Chitinophaga . Strains R156-2T and T58-2 showed the greatest level of sequence similarity with Chitinophaga niabensis (96.0–96.3 %). The major menaquinone was MK-7. The main cellular fatty acids were iso-C15 : 0, C16 : 1ω5c and iso-C17 : 0 3-OH. Phenotypic and genotypic analyses indicated that strains R156-2T and T58-2 could not be assigned to any recognized species. Therefore, strains R156-2T and T58-2 represent a novel species of the genus Chitinophaga , for which the name Chitinophaga cymbidii sp. nov. is proposed. The type strain is R156-2T ( = ACCC 05363T = KCTC 23738T). The DNA G+C content of this strain is 51.9 mol%.

A novel psychrotolerant, strictly aerobic, non-motile, rod-shaped bacterial strain, designated IM13T, was isolated from a sample taken from prehistoric guano paintings in Magura Cave, northwest Bulgaria and subjected to a polyphasic taxonomic study. Strain IM13T formed yellow colonies on LB agar plates and was Gram-staining-negative, heterotrophic and alkalitolerant. It grew optimally at pH 7.5 and 30 °C in the absence of NaCl. Phylogenetic analysis of the whole 16S rRNA gene revealed that strain IM13T branched with representatives of the genus Myroides with sequence similarity of 93–94 % with other species of the genus. The novel isolate contained iso-C15 : 0 (49.1 %), iso-C17 : 1ω9c (18.2 %) and iso-C17 : 0 3-OH (14.0 %) as dominant fatty acids. The DNA G+C content of strain IM13T was 33.5 mol%. Based on phylogenetic inference and phenotypic characteristics, it was concluded that strain IM13T represents a novel species of the genus Myroides , for which the name Myroides guanonis sp. nov. is proposed.
