摘要:	Strain G18T, a Gram-negative, aerobic, rod-shaped, motile, non-fermentative, yellow-pigmented bacterium, was isolated from the Red Sea sediment. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strain G18T was most closely related to Phaeocystidibacter luteus PG2S01T with 95.3 % similarity. Growth of strain G18T occurred at 10-42 C (optimum 28-37 C), pH 5.0-9.0 (optimum pH 6.0-8.0) and in the presence of 0.5-10 % NaCl (optimum 2-5 %). The major fatty acids of strain G18T were iso-C15:0, summed feature 3 (C16:1omega7c and/or C16:1omega6c), iso-C15:1 G and iso-C17:0 3-OH. The major polar lipids were phosphatidylethanolamine, unidentified aminolipids, phospholipids and other lipids. The predominant quinone was menaquinone 6 (MK-6). The G+C content of the genomic DNA from strain G18T was 39.0 mol%. Based on the phylogenetic and phenotypic properties, strain G18T represents a novel species of the genus Phaeocystidibacter, for which the name Phaeocystidibacter marisrubri sp. nov. is proposed. The type strain is G18T (=CGMCC 1.14954T =JCM 30614T).
