sp. nov., a novel hydrocarbon-degrading bacterium isolated from deep chlorophyll maximum layer seawater of the West Pacific Ocean and emended description of the genus Free

Abstract

A Gram-stain-negative, motile, non-spore-forming, strictly aerobic and rod-shaped bacterial strain, Adcm-6A, was isolated from a seawater sample collected from the deep chlorophyll maximum layer in the West Pacific Ocean. Strain Adcm-6A grew at 20–37 °C (optimum, 28–32 °C), at pH 6–11 (pH 7) and in the presence of 0–6 % (1–2 %) NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequences indicated that it belonged to the genus and had 97.7 and 96.9 % sequence similarity to DSM 1231 and JCM 32263, respectively. Digital DNA–DNA hybridization and average nucleotide identity values between strain Adcm-6A and the two type strains were 22.2–22.9 % and 79.7–80.4 %, respectively. The principal fatty acids were C cyclo 8, summed feature 8 (C 6 and/or C 7) and C. The predominant respiratory quinone was Q-10. The polar lipids were diphosphatidylglycerol, two phosphatidylethanolamines, two phosphatidyglycerols and an unidentified lipid. The genomic DNA G+C content of strain Adcm-6A was 67.7 %. Based on phylogenetic analysis and genomic-based relatedness indices, as well as phenotypic and genotypic characteristics, strain Adcm-6A represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is Adcm-6A (=MCCC M24951=KCTC 82849).
