( 2006 ) Thalassomonas agarivorans sp. nov., a marine agarolytic bacterium isolated from shallow coastal water of An-Ping Harbour, Taiwan, and emended description of the genus Thalassomonas. PMID : 16738099 DOI : 10.1099/ijs.0.64130-0 Abstract >>
A marine agarolytic bacterium, designated strain TMA1(T), was isolated from a seawater sample collected in a shallow-water region of An-Ping Harbour, Taiwan. It was non-fermentative and Gram-negative. Cells grown in broth cultures were straight or curved rods, non-motile and non-flagellated. The isolate required NaCl for growth and exhibited optimal growth at 25 degrees C and 3 % NaCl. It grew aerobically and was incapable of anaerobic growth by fermenting glucose or other carbohydrates. Predominant cellular fatty acids were C(16 : 0) (17.5 %), C(17 : 1)omega8c (12.8 %), C(17 : 0) (11.1 %), C(15 : 0) iso 2-OH/C(16 : 1)omega7c (8.6 %) and C(13 : 0) (7.3 %). The DNA G + C content was 41.0 mol%. Phylogenetic, phenotypic and chemotaxonomic data accumulated in this study revealed that the isolate could be classified in a novel species of the genus Thalassomonas in the family Colwelliaceae. The name Thalassomonas agarivorans sp. nov. is proposed for the novel species, with TMA1(T) (=BCRC 17492(T) = JCM 13379(T)) as the type strain.

( 2014 ) Description of Thalassotalea piscium gen. nov., sp. nov., isolated from flounder (Paralichthys olivaceus), reclassification of four species of the genus Thalassomonas as members of the genus Thalassotalea gen. nov. and emended description of the genus Thalassomonas. PMID : 24421274 DOI : 10.1099/ijs.0.055913-0 Abstract >>
A Gram-staining-negative, aerobic, rod-shaped bacterium, designated strain T202(T), was isolated from the gill of a cultured flounder (Paralichthys olivaceus). Based on 16S rRNA gene sequence similarity, strain T202(T) was a member of the family Colwelliaceae and shared 93.32-96.58 % similarity with type strains of all members of the most closely related genus Thalassomonas. Phylogenetically, the isolate shared a root with the type strains of four marine species, Thalassomonas agariperforans M-M1(T), Thalassomonas agarivorans TMA1(T), Thalassomonas loyana CBMAI 722(T) and Thalassomonas ganghwensis JC2041(T). Optimal growth occurred in the presence of 2-4 % (w/v) NaCl, at pH 7.0-8.0 and at 28 �XC. Ubiquinone 8 (Q-8) was the predominant respiratory quinone. The major fatty acids were C16 : 0, summed feature 3 (C16 : 1�s7c and/or C16 : 1�s6c), C16 : 1�s9c and C17 : 1�s8c. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content of strain T202(T) was 37 mol%. On the basis of polyphasic analysis, especially the phylogenetic relationships and the lower DNA G+C content, strain T202(T) is considered to represent a novel species in a new genus, for which the name Thalassotalea piscium gen. nov., sp. nov. is proposed. The type strain of Thalassotalea piscium is T202(T) (= JCM 18590(T) = DSM 26287(T) = KCTC 32144(T)). Because Thalassomonas agariperforans M-M1(T), Thalassomonas agarivorans TMA1(T), Thalassomonas loyana CBMAI 722(T) and Thalassomonas ganghwensis JC2041(T) formed a phylogenetic group together with strain T202(T) that was clearly separated from other known strains of Thalassomonas, these four species are reclassified as members of the genus Thalassotalea as Thalassotalea agariperforans comb. nov. (type strain M-M1(T) = KCTC 23343(T) = CCUG 60020(T)), Thalassotalea agarivorans comb. nov. (type strain TMA1(T) = BCRC 17492(T) = JCM 13379(T) = DSM 19706(T)), Thalassotalea loyana comb. nov. (type strain CBMAI 722(T) = LMG 22536(T)) and Thalassotalea ganghwensis comb. nov. (type strain JC2041(T) = IMSNU 14005(T) = KCTC 12041(T) = DSM 15355(T)). The type species of the genus Thalassotalea is Thalassotalea ganghwensis gen. nov., comb. nov. An emended description of the genus Thalassomonas is also proposed.
