Clarion Clipperton Fracture Zone

A Gram-stain-negative, strictly aerobic, non-motile, rod-shaped, manganese-oxidizing bacterial strain, designated DY2–5T, was isolated from surface sediment of Pacific Clarion-Clipperton Fracture Zone (CCFZ). Growth occurred at 0–37 °C (optimum 28 °C), pH 6.5–9.0 (optimum pH 7.0–7.5) and in the presence of 1–11 % (w/v) NaCl (optimum 3–4 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that the novel strain was most closely related to Celeribacter halophilus ZXM137T with 96.13 % sequence similarity, and had 16S rRNA gene sequence similarities in the range 93.89–95.87 % with other species of the genus Celeribacter. The dominant fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The polar lipids of strain DY2–5T comprised phosphatidylglycerol, phosphatidylcholine and two unknown aminolipids. The major respiratory quinone was ubiquinone–10 (Q–10). The DNA G+C content of strain DY2–5T was 64.8 mol%. On the basis of the phenotypic, genotypic and physiological evidence, strain DY2–5T represents a novel species of the genus Celeribacter, for which the name Celeribacter manganoxidans sp. nov. is proposed. The type strain is DY2–5T ( = JCM 19384T = KCTC 32473T).

A yellow-pigmented bacterial strain, designated Y2T, was isolated from farmland soil in Bengbu, Anhui province, China. Cells of strain Y2T were Gram-stain-negative, strictly aerobic, non-motile and rod-shaped. Strain Y2T grew optimally at pH 7.0, 30 °C and in the presence of 2 % (w/v) NaCl. The DNA G+C content was 68.9 mol%. The major fatty acids (>5 %) were iso-C15 : 0, iso-C17 : 0, summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1ω9c), iso-C11 : 0 3-OH and iso-C11 : 0. The major respiratory quinone was ubiquinone-8 (Q-8), and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain Y2T was most closely related to Luteimonas mephitis B1953/27.1T (99.1 % 16S rRNA gene sequence similarity), followed by Luteimonas lutimaris G3T (98.6 %), Luteimonas abyssi XH031T (96.2 %) and Luteimonas aquatica RIB1-20T (96.0 %). Strain Y2T exhibited low DNA–DNA relatedness with Luteimonas mephitis B1953/27.1T (43.6 ± 0.5 %) and Luteimonas lutimaris G3T (43.9 ± 2.1 %). On the basis of phenotypic, genotypic and phylogenetic evidence, strain Y2T represents a novel species of the genus Luteimonas, for which the name Luteimonas soli sp. nov. is proposed.
