Abstract
Two bacterial strains, designated SS33T and Y03T, 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 SS33T was found to be closely related to
Primorskyibacter marinus
PX7T,
Pelagivirga dicentrarchi
YLY04T,
Palleronia marisminoris
DSM 26347T and
Maribius pontilimi
GH1-23T with 94.8, 94.6, 94.5 and 94.5 % sequence similarity; strain Y03T was found to be closest to
Flavivirga aquimarina
EC2D5T,
Flavivirga eckloniae
ECD14T and
Flavivirga amylovorans
JC2681T with 96.4, 96.1 and 96.0 % sequence similarity. Strain SS33T 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 SS33T showed that the predominant respiratory quinone was ubiquinone-10. The major fatty acids (>10.0 %) included C18 : 1
ω7c and C16 : 0. The major polar lipids included phosphatidylglycerol, phosphatidylcholine, one unidentified phospholipid, one unidentified glycolipid, one unidentified polar lipid and two unidentified aminolipids. Strain Y03T 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-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH and iso-C15 : 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 SS33T 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 SS33T (=KCTC 62986T=MCCC 1H00387T). Strain Y03T 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 Y03T (=KCTC 72001T=MCCC 1H00386T).
