资助者: We are grateful to Professor Hans-Peter Klenk for providing the type strain, Melghirimyces algeriensis DSM 45474T. This research was supported by the National Basic Research Program of China (no. 2010CB833801), the National Natural Science Foundation of China (nos 41106139 and 41230962) and the Academic Frontier Project for young researchers (no. SQ201013).
摘要: A novel filamentous bacterium, strain SCSIO 11153(T), was isolated from a sediment sample collected from the Indian Ocean (80 degrees 03.099' E 01 degrees 03.300' N) at a depth of 4593 m. Good growth was observed at 50-55 degrees C and pH 7.0 with 3% NaCl. It formed ivory white colonies with radial wrinkles. Aerial mycelium was absent on the media tested. Phenotypic characteristics and 16S rRNA gene sequence analysis indicated that strain SCSIO 11153(T) belonged to the family Thermoactinomycetaceae. It exhibited 96.4% and 96.2% 16S rRNA gene sequence similarities to Melghirimyces algeriensis NariEX(T) and Melghirimyces thermohalophilus Nari11A(T), respectively, while lower sequence similarity values (<95.4%) were observed between strain SCSIO 11153(T) and other species of genera in the family Thermoactinomycetaceae. The menaquinone type was MK-7. Major cellular fatty acids were iso-C-15:0, anteiso-C-15:0 and isoC(17:0). The polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content of strain SCSIO 11153(T) was 52.6 mol%. On the basis of the genotypic and phenotypic characteristics, it is proposed that strain SCSIO 11153(T) represents a novel species of the genus Melghirimyces with the name Melghirimyces profundicolus sp. nov. The type strain is SCSIO 11153(T) (=DSM 45787(T)=CCTCC AA 2012007(T)=NBRC 109068(T)).
