Deep Subseafloor

A facultatively anaerobic bacterium, designated strain 1MBB1T, was isolated from basaltic breccia collected from 341 m below the seafloor by seafloor drilling of Rigil Guyot during Integrated Ocean Drilling Program Expedition 330. The cells were straight rods, 0.5 μm wide and 1–3 μm long, that occurred singly and in chains. Strain 1MBB1T stained Gram-positive. Catalase and oxidase were produced. The isolate grew optimally at 30 °C and pH 7.5, and could grow with up to 12 % (w/v) NaCl. The DNA G+C content was 40.5 mol%. The major cellular fatty acids were C16: 1ω11c (26.5 %), anteiso-C15: 0 (19.5 %), C16: 0 (18.7 %) and iso-C15: 0 (10.4 %), and the cell-wall diamino acid was meso-diaminopimelic acid. Endospores of strain 1MBB1T oxidized Mn(II) to Mn(IV), and siderophore production by vegetative cells was positive. Phylogenetic analysis of the 16S rRNA gene indicated that strain 1MBB1T was a member of the family Bacillaceae, with Bacillus foraminis CV53T and Bacillus novalis LMG 21837T being the closest phylogenetic neighbours (96.5 and 96.2 % similarity, respectively). This is the first novel species described from deep subseafloor basaltic crust. On the basis of our polyphasic analysis, we conclude that strain 1MBB1T represents a novel species of the genus Bacillus, for which we propose the name Bacillus rigiliprofundi sp. nov. The type strain is 1MBB1T ( = NCMA B78T = LMG 28275T).

The taxonomic position of an actinomycete isolated from deep-sea sediment from the Indian Ocean was determined by using a polyphasic approach. The presence of iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0, iso-C17 : 0 and anteiso-C17 : 0 as the major cellular fatty acids, ll-diaminopimelic acid as the characteristic diamino acid, and MK-9(H4, H6 and H8) as the major menaquinones supported the affiliation of strain IH32-1T to the genus Streptomyces. Comparison of 16S rRNA gene sequences showed that strain IH32-1T exhibited highest similarities to the type strains of Streptomyces globosus (97.6 %) and Streptomyces toxytricini (97.6 %). However, DNA–DNA relatedness values between strain IH32-1T and the type strains of S. globosus and S. toxytricini were determined as 55.2±4.7 and 38.3±2.5 %, respectively. Based on its chemotaxonomic, phenotypic and genotypic characteristics, strain IH32-1T is considered to represent a novel species in the genus Streptomyces, for which the name Streptomyces indicus sp. nov. is proposed. The type strain is IH32-1T ( = DSM 42001T = CGMCC 4.5727T).

A novel halophilic bacterium, designated strain MSS4T, was isolated from the solar salterns of Mesolongi, Greece. The micro-organism, a motile, Gram-stain-positive, aerobic rod, proliferated at salinities of 1.0–4.0 M NaCl, with optimal growth at 2.5 M NaCl. Endospores were not observed. Strain MSS4T showed optimal growth at 37 °C and pH 8.0. The G+C content of its DNA was 47.2 mol%. The polar lipid pattern of strain MSS4T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidic acid and phosphatidylethanolamine. It possessed anteiso-C15 : 0, C18 : 0, C16 : 0 and anteiso-C17 : 0 as the major fatty acids (altogether representing 84.7 % of the total). The predominant isoprenoid quinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. 16S rRNA gene sequence analysis showed that the new isolate has 96.1 % similarity to Bacillus qingdaonensis CM1T and Bacillus aidingensis 17-5T, 95.5 % to Bacillus salarius BH169T and lower similarity to other Bacillus species. These results justify the assignment of strain MSS4T to a novel species within the genus Bacillus, for which the name Bacillus halochares sp. nov. is proposed. The type strain is MSS4T (=LMG 24571T =DSM 21373T).

Two novel filamentous bacteria, strains SCSIO 11157T and SCSIO 11154T, were isolated from a deep-sea sediment sample. Strain SCSIO 11157T grew optimally at 55–60 °C, while strain SCSIO 11154T grew optimally at 40 °C. Both strains produced aerial and substrate mycelia. Phylogenetic analysis of the 16S rRNA gene sequences of strains SCSIO 11157T and SCSIO 11154T showed that the isolates were affiliated to the family Thermoactinomycetaceae. The two isolates contained ll-diaminopimelic acid as the cell-wall diamino acid, and did not have diagnostic sugars. The major polar lipids of strain SCSIO 11157T were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol, and the major polar lipids of SCSIO 11154T were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The predominant menaquinone of both strains was MK-7. The major cellular fatty acids of strain SCSIO 11157T were iso-C15 : 0, C18 : 1ω9c and iso-C17 : 0, and strain SCSIO 11154T contained iso-C15 : 0 and iso-C17 : 0 as major fatty acids. The DNA G+C contents of strains SCSIO 11157T and SCSIO 11154T were 54.2 and 51.8 mol %, respectively. On the basis of its phenotypic and phylogenetic properties, strain SCSIO 11157T represents a novel species in the new genus, for which we propose the name Marinithermofilum abyssi gen. nov., sp. nov. The type strain of Marinithermofilum abyssi is SCSIO 11157T ( = CGMCC 1.15179T = NBRC 109939T). Strain SCSIO 11154T represents a novel species of the genus Desmospora, for which we propose the name Desmospora profundinema sp. nov. The type strain is SCSIO 11154T ( = DSM 45903T = NBRC 109626T).
