A bacterial strain, designated Coryn-1T, was isolated from mucus of the coral Fungia granulosa (northern Red Sea, Gulf of Eilat, Israel) by growth and enrichment of micro-organisms in agar spheres and subsequent plating. The bacterium was found to be a Gram-positive, non-motile, halotolerant, heterotrophic coccobacillus. Comparative 16S rRNA gene sequence analyses showed that strain Coryn-1T belonged to the genus Corynebacterium, exhibiting the highest levels of similarity (94 %) with the 16S rRNA gene sequence of Corynebacterium halotolerans YIM 70093T. The novel strain grew well at 0.5–4.0 % salinity, at pH 7.2–9.0 and at 30–37 °C. The major cellular fatty acids were oleic acid (C18 : 1
9c; 58 %), palmitic acid (C16 : 0; 30 %) and tuberculostearic acid (10-methyl-C18 : 0; 12 %). The DNA G+C content was 66.6 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Coryn-1T represents a novel species, for which the name Corynebacterium maris sp. nov. is proposed. The type strain is Coryn-1T (=DSM 45190T=LMG 24561T).
An extended phylogenetic tree based on 16S rRNA gene sequences is available as supplementary material with the online version of this paper.
