从太平洋深海中分离到一株海洋假囊菌,命名为P-1 km-3(T)。菌株P-1 km-3(T)的细胞为革兰氏染色阴性、需氧、过氧化氢酶和氧化酶阳性、具有单极前鞘或鞭毛的二型杆状细胞。该菌株水解明胶并在6-40 °C(最佳,30 °C)和0.5-12%(w/v)NaCl(最佳,2%)下生长。16 S rRNA基因序列的系统发育分析表明,菌株P-1 km-3(T)属于α变形菌纲丝单胞菌科,代表一个独立的谱系,位于Oceanicaulis和Woodsholea属之间。P-1 km-3(T)菌株与Oceanicaulis和Woodsholea属的模式菌株的序列相似性为93.2- 93.9%。菌株P-1 km-3(T)的主要脂肪酸为C18:1ω 7 c、C18:0、11-甲基C18:1ω 7 c、C17:0和C19:0环ω 8 c。菌株P-1 km-3(T)的主要呼吸醌为Q-10。菌株P-1 km-3(T)的极性脂质包括葡萄糖醛酸吡喃糖基甘油二酯(GUDG)、单糖基甘油二酯(MGDG)、磺基奎诺糖基甘油二酯(SQDG)、磷脂酰甘油(PG)、一种未鉴定的磷脂(PL)和一种未鉴定的脂质(L)。菌株P-1 km-3(T)基因组DNA G+C含量为66.0mol%。根据本研究中所提供的多相数据,提出菌株P-1 km-3(T)代表一个新属中的一个新种,太平洋海尾虫(Marinicauda pacifica gen. nov.)sp. nov.,属于丝单胞菌科。模式种的模式株为P-1 km-3(T)(=KACC 16526(T)=CGMCC 1.11031(T))。
A marine prosthecate bacterium, designated strain P-1 km-3(T), was isolated from deep seawater from the Pacific. Cells of strain P-1 km-3(T) were Gram-stain-negative, aerobic, catalase- and oxidase-positive, dimorphic rods with a single polar prostheca or flagellum. The strain hydrolysed gelatin and grew at 6-40 °C (optimum, 30 °C) and with 0.5-12% (w/v) NaCl (optimum, 2%). Phylogenetic analysis of the 16S rRNA gene sequences revealed that strain P-1 km-3(T) belonged to the family Hyphomonadaceae in the class Alphaproteobacteria and represented a separate lineage, located between the genera Oceanicaulis and Woodsholea. Sequence similarities of strain P-1 km-3(T) with type strains of species of the genera Oceanicaulis and Woodsholea were 93.2-93.9%. The predominant cellular fatty acids in strain P-1 km-3(T) were C18:1ω7c, C18:0, 11-methyl C18:1ω7c, C17:0 and C19:0 cyclo ω8c. The major respiratory quinone of strain P-1 km-3(T) was Q-10. The polar lipids of strain P-1 km-3(T) comprised glucuronopyranosyldiglyceride (GUDG), monoglycosyldiglyceride (MGDG), sulfo-quinovosyl diacylglycerol (SQDG), phosphatidylglycerol (PG), an unidentified phospholipid (PL) and an unidentified lipid (L). The genomic DNA G+C content of strain P-1 km-3(T) was 66.0 mol%. On the basis of the polyphasic data presented in this study, strain P-1 km-3(T) is proposed to represent a novel species in a new genus, Marinicauda pacifica gen. nov., sp. nov., within the family Hyphomonadaceae. The type strain of the type species is P-1 km-3(T) (=KACC 16526(T)=CGMCC 1.11031(T)).
