Description of Pseudobacteriovorax antillogorgiicola gen. nov., sp. nov., a bacterium isolated from the gorgonian octocoral Antillogorgia elisabethae, belonging to the family Pseudobacteriovoracaceae fam. nov., within the order Bdellovibrionales.
A bacterial strain designated RKEM611(T) was isolated from the octocoral Antillogorgia elisabethae, collected off the coast of San Salvador, The Bahamas. The strain is Gram-stain-negative, an obligate aerobe, and pleomorphic. It requires NaCl for growth and exhibits optimal growth at 1-2 % (w/v) NaCl, 30-37 °C and pH 6.0-8.0. The predominant cellular fatty acids are C16 : 1ω5c and C16 : 0; the major respiratory quinone is menaquinone MK-6, and the DNA G+C content is 46.3 mol%. Based on phylogenetic analysis of the 16S rRNA gene, in addition to phenotypic characteristics, RKEM611(T) represents a novel species and genus of a novel family within the order Bdellovibrionales. The names Pseudobacteriovoracaceae fam. nov. and Pseudobacteriovorax antillogorgiicola gen., nov., sp., nov. are proposed. Isolate RKEM611(T) ( = NCCB 100521(T) = LMG 28452(T)) is the type strain.
