Abstract

A novel aerobic bacterium, designated strain PIII.02, was isolated from a Mediterranean sponge () collected off the Israeli coast near Sdot Yam. The non-motile cells were Gram-staining-negative, oxidase-positive and catalase-positive. The orange pigment of colonies growing on marine agar was neither diffusible nor flexirubin-like. Strain PIII.02 grew at 15–35 °C, at pH 6.0–9.0, with 2.0–7.0 % (w/v) NaCl, and with 1.0-8.0 % (w/v) sea salts. The predominant fatty acids were iso-C, iso-C H, iso-C, C, anteiso-C and Cω7. The major respiratory quinone was MK-7. The genomic DNA G+C content of the novel strain was 38.1 mol%. Results from 16S rRNA gene sequence analysis indicated that strain PIII.02 was distantly related to established members of the phylum . The established species found to be most closely related to the novel strain was NCIMB 1402 (87.6 % 16S rRNA gene sequence similarity). Based on the phenotypic and chemotaxonomic data and the results of the phylogenetic analyses, strain PIII.02 represents a novel species of a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain is PIII.02 ( = ATCC BAA-2393  = LMG 26723).
