| 摘要: | Strain G18(T), a Gram-stain-negative, aerobic, rod-shaped, motile, non-fermentative, yellow-pigmented bacterium, was isolated from Red Sea sediment. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain G18(T) was most closely related to Phaeocystidibacter luteus PG2S01(T) with 95.3% similarity. Growth of strain G18(T) occurred at 10-42 degrees C (optimum 28-37 degrees 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 G18(T) were iso-C-15:0, summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c), iso-C-15:1 G and iso-C-17:0 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 G18(T) was 39.0 mol%. Based on the phylogenetic and phenotypic properties, strain G18(T) represents a novel species of the genus Phaeocystidibacter, for which the name Phaeocystidibacter marisrubri sp. nov. is proposed. The type strain is G18(T) (=CGMCC 1.14954(T)=JCM 30614(T)). |
