资助者: We are grateful to Professor Tomohiko Tamura for providing G. muralis NBRC 103560T, G. thermotolerans NBRC 104148T and G. ruanii NBRC 103883T, and also grateful to Dr Peter Schumann for analysis of the peptidoglycan structure. This research was supported by the National Basic Research Program of China (no. 2010CB833801) and the National Natural Science Foundation of China (nos. 41230962, 41106139).
摘要: A Gram-stain-positive actinobacterium, designated strain SCSIO 15020(T), was isolated from sediment of the South China Sea, and characterized by using a polyphasic approach. The temperature range for growth was 24-60 degrees C, with optimal growth occurring at 50 C. The pH range for growth was 6-10 (optimum pH 8-9). The NaCl concentration range for growth was 0 5 % (w/v). The peptidoglycan type was A4 alpha. Polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown polar lipid. The major menaquinone was MK-8(H-4); MK-7(H-4) was present as a minor component. The major fatty acids (>5 %) were anteiso-C-15:0, iso-C-15:0 and iso-C-16:0 The DNA G+C content of strain SCSIO 15020T was 73.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 15020(T) belonged to the genus Georgenia, with the closest neighbours being Georgenia muralis 1A-C-T (96.3% similarity), Georgenia thermotolerans TT02-04(T) (95.7%) and Georgenia ruanii YIM 004(T) (95.6%). Based on evidence from the present polyphasic study, strain SCSIO 15020(T) is considered to represent a novel species of the genus Georgenia, for which the name Georgenia sediminis sp. nov. is proposed. The type strain is SCSIO 15020(T) (=DSM 25884(T)= NBRC 108941(T)).
