In this study, we reported a Gram-stain-negative, orange-coloured, rod-shaped, motile and faculatively anaerobic bacterium named strain PB63T, which was isolated from the deep-sea sediment from the Mariana Trench. Growth of PB63T occurred at 10–35 °C (optimum, 28 °C), pH 5.0–8.0 (optimum, 5.0–6.0) and with 0–7 % (w/v) NaCl (optimum, 2–3 %). The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that PB63T represented a member of the genus Novosphingopyxis and was closely related to Novosphingopyxis baekryungensis DSM 16222T (97.9 % sequence similarity). PB63T showed tolerance to a variety of heavy metals, including Co2+, Zn2+, Mn2+ and Cu2+. The complete genome of PB63T was obtained, and many genes involved in heavy metal resistance were found. The genomic DNA G+C content of PB63T was 62.8 mol%. The predominant respiratory quinone of PB63T was ubiquinone-10 (Q-10). The polar lipids of PB63T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid, glycolipid, phosphatidylcholines and three unidentified lipids. The major fatty acids of PB63T included summed feature 8 (C18 : 1ω7c or/and C18 : 1ω6c), C14 : 0 2-OH, 11-methyl C18 : 1ω7c, C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C17 : 1ω6c. The results of phylogenetic, physiological, biochemical and morphological analyses indicated that strain PB63T represents a novel species of the genus Novosphingopyxis , and the name Novosphingopyxis iocasae sp. nov. is proposed with the type species PB63T (=CCTCC AB 2019195T=JCM 34178T).

A taxonomic study was carried out on strain PA15-N-34T, which was isolated from deep-sea sediment of Pacific Ocean. The bacterium was Gram-stain-positive, oxidase- and catalase-positive and rod-shaped. Growth was observed at salinity of 0–15.0% NaCl and at temperatures of 10–45 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PA15-N-34T belonged to the genus Alcanivorax , with the highest sequence similarity to Alcanivorax profundi MTEO17T (97.7 %), followed by Alcanivorax nanhaiticus 19 m-6T (97.3 %) and 12 other species of the genus Alcanivorax (93.4 %–97.0 %). The average nucleotide identity and DNA–DNA hybridization values between strain PA15-N-34T and type strains of the genus Alcanivorax were 71.46–81.78% and 18.7–25.2 %, respectively. The principal fatty acids (>10 %) were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c; 31.2 %), C16 : 0 (25.0 %) and summed feature 3 (14.6 %). The DNA G+C content was 57.15 mol%. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, four unidentified aminolipids and three unidentified lipids. The novel strain can be differentiated from its closest type strain by a negative test for urease and the presence of diphosphatidylglycerol and aminolipid. The combined genotypic and phenotypic data show that strain PA15-N-34T represents a novel species within the genus Alcanivorax , for which the name Alcanivorax sediminis sp. nov. is proposed, with the type strain PA15-N-34T (=MCCC 1A14738T=KCTC 72163T).
