A Gram-negative, spirilla, non-spore-forming, motile and strictly aerobic bacterium, designated HK-33T , was isolated from a mangrove sediment sample in Haikou city, Hainan Province, China. Strain HK-33T was able to grow at 10-45 °C (optimum 37 °C), 0.5-12.0 % (w/v) NaCl (2.0 %, w/v) and pH 5.5-8.5 (pH 7.0). The major cellular fatty acids were C16 : 0 and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). Ubiquinone-8 was the predominant respiratory quinone, and Q-9 was present in trace amounts...

The draft whole-genome sequence of Arcobacter haliotis strain LMG 28652T was obtained and compared against the type strain of Arcobacter lekithochrous LFT 1.7T . High similarity was found between the two strains, showing average nucleotide identity and in silico DNA-DNA hybridization values of 98.40 and 86.10 %, respectively. These values indicated that both genomes belonged to the same species, confirming the evidences derived from the phylogenetic analysis performed with the 16S rRNA gene and the concatenated sequences of five housekeeping genes...

A strictly aerobic, catalase-negative and oxidase-positive bacterium (HR-BBT ), isolated from a water sample of the Han River, was taxonomically studied using a polyphasic approach. Cells were Gram-stain-negative motile rods with a polar flagellum. The strain grew at 20-35 °C and pH 7-8 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HR-BBT belonged to the family Nevskiaceae in the phylum Proteobacteria and formed a phylogenic lineage with members of the genus Solimonas...

Cyanobacteria is an ancient phylum of oxygenic photosynthetic microorganisms found in almost all environments of Earth. In recent years, the taxonomic placement of some cyanobacterial strains, including those belonging to the genus Nostocsensu lato, have been reevaluated by means of a polyphasic approach. Thus, 16S rRNA gene phylogeny and 16S-23S internal transcribed spacer (ITS) secondary structures coupled with morphological, ecological and physiological data are considered powerful tools for a better taxonomic and systematics resolution, leading to the description of novel genera and species...

A polyphasic study was undertaken to establish the taxonomic status of a Blastococcus strain isolated from an extreme hyper-arid Atacama Desert soil. The isolate, strain P6T , was found to have chemotaxonomic and morphological properties consistent with its classification in the genus Blastococcus. It was shown to form a well-supported branch in the Blastococcus 16S rRNA gene tree together with the type strains of Blastococcus capsensis and Blastococcus saxobsidens and was distinguished from the latter, its close phylogenetic neighbour, by a broad range of phenotypic properties...
