Limibaculum sediminis sp. nov., isolated from mangrove sediment

A Gram-stain-negative, cream-coloured, aerobic, motile and ovoid- to rod-shaped bacterium, designated as FT325 T , was isolated from mangrove sediment collected in Shenzhen, PR China. The taxonomic position of strain FT325 T was established by phylogenetic, physiological, biochemical and chemotaxonomic analyses. Strain FT325 T grew optimally at 37–40 °C and pH 6.0 in the presence of 0 % (w/v) NaCl. Results of 16S rRNA gene sequence analysis showed that strain FT325 T was most similarly related to Limibaculum halophilum CAU 1123 T (96.2 %), Phaeovulum vinaykumarii DSM 18714 T (93.9%) and Amaricoccus solimangrovi HB 172011 T (93.7 %). The major fatty acids (>10 %) were C 18 : 1 ω 7 c (60.0 %) and 11-methyl C 18 : 1 ω 7 c (16.7 %). The sole respiratory quinone was Q-10. The polar lipids were phosphatidylglycerol, one unidentified glycolipid, three unidentified aminolipids and three unidentified phospholipids. Its estimated genome size was 4 318 768 bp and the genomic DNA G+C content was 69.6 mol%. Based on its distinct phenotypic, chemotaxonomic and phylogenetic characteristics, strain FT325 T represents a novel species of the genus Limibaculum , for which the name Limibaculum sediminis sp. nov. is proposed (=MCCC 1K07397 T =KCTC 92313 T ).
