( 2011 ) Aquimarina spongiae sp. nov., isolated from marine sponge Halichondria oshoro. PMID : 20348323 DOI : 10.1099/ijs.0.022046-0 Abstract >>
A Gram-stain-negative, yellow-pigmented, rod-shaped, strictly aerobic, non-flagellated, non-gliding and oxidase- and catalase-positive bacterium, designated A6(T), was isolated from a marine sponge, Halichondria oshoro, collected on the coast of Jeju Island, South Korea. Phylogenetic analysis based on the nearly complete 16S rRNA gene sequence revealed that strain A6(T) was a member of the family Flavobacteriaceae. The closest relatives were Aquimarina intermedia LMG 23204(T), A. latercula ATCC 23177(T), A. brevivitae SMK-19(T) and A. muelleri KMM 6020(T), with which strain A6(T) shared 95.7, 95.1, 94.7 and 94.6 % 16S rRNA gene sequence similarity, respectively. The dominant fatty acids of strain A6(T) were iso-C(15 : 0) (32.2 %), iso-C(17 : 0) 3-OH (20.0 %), iso-C(15 : 0) 3-OH (12.3 %), iso-C(15 : 1) G (7.2 %) and summed feature 3 (comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)�s7c; 6.8 %). The DNA G+C content of strain A6(T) was 36.0 mol% and the major respiratory quinone was MK-6. On the basis of combined phenotypic and phylogenetic analyses, strain A6(T) represents a novel species of the genus Aquimarina, for which the name Aquimarina spongiae sp. nov. is proposed. The type strain is A6(T) (=KCTC 22663(T) =DSM 22623(T)).

( 2013 ) Aquimarina gracilis sp. nov., isolated from the gut microflora of a mussel, Mytilus coruscus, and emended description of Aquimarina spongiae. PMID : 22941302 DOI : 10.1099/ijs.0.044289-0 Abstract >>
An orange-coloured and slender rod-shaped bacterium, designated strain PSC32(T), was isolated from the gut microflora of a mussel collected from Gwangyang Bay, South Sea (Republic of Korea). Cells were Gram-reaction-negative, strictly aerobic, and catalase- and oxidase-positive. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. The only isoprenoid quinone of strain PSC32(T) was MK-6 and the DNA G+C content was 36.9 mol%. Phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids were found as major polar lipids. A phylogenetic tree based on 16S rRNA gene sequences showed that strain PSC32(T) forms an evolutionary lineage within the genus Aquimarina and is closely related to Aquimarina spongiae A6(T) (97.0 % similarity) and to other members of the genus Aquimarina (94.4-96.5 %). Genomic DNA-DNA relatedness between strain PSC32(T) and A. spongiae A6(T) was 40.7 %. A number of phenotypic characteristics distinguished strain PSC32(T) from described members of the genus Aquimarina. On the basis of the evidence presented in this study, strain PSC32(T) represents a novel species, for which the name Aquimarina gracilis sp. nov. is proposed. The type strain is PSC32(T) (= KCTC 23301(T) = JCM 17453(T)). An emended description of Aquimarina spongiae is given.
