ABSTRACT
An aerobic, Gram-stain-negative, bacterium, designated CLL3-39T was isolated from seashore sediment collected at a Tamarix chinensis forest in the Marine Ecology Special Reserve of Changyi, Shandong Province, PR China. Cells of strain CLL3-39T were olive-shaped and no flagellum was observed. Strain CLL3-39T grew optimally at 33 °C, pH 7.5 and salinity (sea salts) of 40 g l-1. The main fatty acids in the cell membrane of strain CLL3-39T comprised anteiso-C15ââ0 (22.3â%), iso-C15ââ0 (14.0â%), C16ââ0 (9.2â%) and summed feature 8 (contains C18ââ1 ω7c/C18ââ1 ω6c. 26. 7â%). The main polar lipids of CLL3-39T were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylcholine. The respiratory quinone was Q10. The G+C content of the genomic DNA of strain CLL3-39T was 69.6 mol%. The average nucleotide identity between CLL3-39T and Pseudoroseicyclus aestuarii DB-4T was 74.7â% and the in silico DNA-DNA hybridization value was 20.1â%. Phylogenetically, strain CLL3-39T belonged to the genus Pseudoroseicyclus, branching with only one type strain P. aestuarii DB-4T with 96.3â% 16S rRNA gene similarity, followed by Limimaricola cinnabarinus LL-001T (95.2â%). Based on its phenotypic, phylogenetic and chemotaxonomic characteristics, we propose strain CLL3-39T (=MCCC 1A14815T =KCTC 72665T) as a representative of a novel species in the genus Pseudoroseicyclus, for which the name Pseudoroseicyclus tamaricis sp. nov. is proposed.
