摘要Two novel filamentous bacteria, strains SCSIO 11157(T) and SCSIO 11154(T), were isolated from a deep-sea sediment sample. Strain SCSIO 11157(T) grew optimally at 55-60 degrees C, while strain SCSIO 11154(T) grew optimally at 40 degrees C. Both strains produced aerial and substrate mycelia. Phylogenetic analysis of the 16S rRNA gene sequences of strains SCSIO 11157(T) and SCSIO 1115(T) 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 11157(T) were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol, and the major polar lipids of SCSIO 11154(T) were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The predominant menaquinone of both strains was MK-7. The major cellular fatty acids of strain SCSIO 11157(T) were iso-C-15;0, C-18:1 omega 9c and iso-C-17:0, and strain SCSIO 11154(T) contained iso-C-15:0 and iso-C-17:0 as major fatty acids. The DNA G+C contents of strains SCSIO 11157(T) and SCSIO 11154(T) were 54.2 and 51.8 mol %, respectively. On the basis of its phenotypic and phylogenetic properties, strain SCSIO 11157(T) 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 11157(T) (=CGMCC 1.15179(T)=NBRC 109939(T)). Strain SCSIO 11154(T) represents a novel species of the genus Desmospora, for which we propose the name Desmospora profundinema sp. nov. The type strain is SCSIO 111541 (=DSM 45903(T)=NBRC 109626(T)).
