Formosa maritima sp. nov., isolated from coastal sediment

A Gram-stain-negative, strictly aerobic, gliding-motile, rod-shaped and orange-pigmented bacterium, designated 1494 T , was isolated from marine sediment collected off the coast of Weihai, PR China. Strain 1494 T was found to grow at 4–37 °C (optimum, 30 °C), at pH 6.0–9.0 (pH 7.0) and in the presence of 0–8 % (w/v) NaCl (2 %). Cells were positive for oxidase and catalase activity. The results of 16S rRNA gene based phylogenetic analysis revealed that strain 1494 T belonged to the genus Formosa and exhibited the highest sequence similarity to Formosa spongicola KCTC 22662 T (98.4 %). Menaquinone-6 (MK-6) was detected as the major respiratory quinone. The dominant cellular fatty acids were iso-C 15 : 1 G and iso-C 15 : 0 . The DNA G+C content of strain 1494 T was 31.1 mol%. The major polar lipids included phosphatidylethanolamine, one unidentified phospholipid and one unidentified lipid. Based on its phylogenetic and phenotypic characteristics, strain 1494 T is considered to represent a novel species from the genus Formosa , for which the name Formosa maritima sp. nov. is proposed. The type strain is 1494 T (=KCTC 72531 T =MCCC 1H00385 T ).
