Abstract:
Two bacterial strains, designated SS33 T and Y03 T , were isolated from marine sediment and marine red alga collected on the coast of Weihai, PR China. Based on the results of 16S rRNA gene sequence analysis, strain SS33 T was found to be closely related to Primorskyibacter marinus PX7 T , Pelagivirga dicentrarchi YLY04 T , Palleronia marisminoris DSM 26347 T and Maribius pontilimi GH1-23 T with 94.8, 94.6, 94.5 and 94.5 % sequence similarity; strain Y03 T was found to be closest to Flavivirga aquimarina EC2D5 T , Flavivirga eckloniae ECD14 T and Flavivirga amylovorans JC2681 T with 96.4, 96.1 and 96.0 % sequence similarity. Strain SS33 T grew at 4–37 °C (optimum, 33 °C), at pH 6.0–9.5 (optimum, pH 7.5–8.0) and in the presence of 0–10 % (w/v) NaCl (optimum, 3.0 %). Chemotaxonomic analysis of strain SS33 T showed that the predominant respiratory quinone was ubiquinone-10. The major fatty acids ( 〉 10.0 %) included C 18 : 1 ω 7 c and C 16 : 0 . The major polar lipids included phosphatidylglycerol, phosphatidylcholine, one unidentified phospholipid, one unidentified glycolipid, one unidentified polar lipid and two unidentified aminolipids. Strain Y03 T grew at 15–40 °C (optimum, 28 °C), at pH 6.5–8.0 (optimum, pH 7.0) and in the presence of 0.5–9.0 % (w/v) NaCl (optimum, 2.0%). Chemotaxonomic analysis showed that the predominant respiratory quinone was menaquinone-6. The major fatty acids ( 〉 10.0 %) included iso-C 15 : 0 , iso-C 15 : 1 G, iso-C 17 : 0 3-OH and iso-C 15 : 0 3-OH. The major polar lipids included phosphatidylethanolamine, one unidentified phospholipid, one unidentified aminolipid and four unidentified polar lipids. Based on the polyphasic data, strain SS33 T is considered to represent a novel species of the genus Palleronia , for which the name Palleronia sediminis sp. nov. is proposed, with the type strain SS33 T (=KCTC 62986 T =MCCC 1H00387 T ). Strain Y03 T is considered to represent a novel species of the genus Flavivirga , for which the name Flavivirga algicola sp. nov. is proposed, with the type strain Y03 T (=KCTC 72001 T =MCCC 1H00386 T ).
