从珠江底泥中分离到一株革兰氏阴性、杆状、非运动、能降解多环芳烃芘的好氧细菌，命名为PrR 001。16 S rRNA基因序列分析表明，该菌株隶属于α-变形菌纲Rhodoproteobacteria aceae的Defluviimonas属，与模式菌株Defluviimonas indica 20 V17 T的相似性为96.3%。 菌株PrR 001 T的DNA G+C含量为68.3mol%。主要的细胞脂肪酸包括总特征8（C18：1ω 7 c/C18：1ω6c）、C19：0环ω 8 c、C18：03 OH和C18：0。 唯一的呼吸脂醌是泛醌-10。主要极性脂质为二磷脂酰甘油、磷脂酰胆碱、磷脂酰乙醇胺、磷脂酰甘油、一种未鉴定的氨基脂质、一种未鉴定的氨基磷脂和三种未鉴定的磷脂。通过生理生化和系统发育分析，将PrR 001 T菌株命名为Defluviimonaspyrenivoranssp.十一是建议。模式菌株Defluviimonaspyrenivoransis PrR 001 T（=CICC 24263 T =KCTC 62192 T）。
An aerobic, Gram-stain-negative, rod-shaped, non-motile bacterium capable of degrading the polycyclic aromatic hydrocarbon pyrene was isolated from sediment of Pearl River and designated PrR001. 16S rRNA gene sequence analysis revealed that this strain was affiliated within the genusDefluviimonasin the familyRhodobacteraceaeof the classAlphaproteobacteriaand showed great similarity with the type strainDefluviimonas indica20V17T(96.3 % similarity). The DNA G+C content of strain PrR001Twas 68.3 mol%. The major cellular fatty acids comprised summed feature 8 (C18 : 1ω7c/C18 : 1ω6c), C19 : 0cycloω8c, C18 : 03OH, and C18 : 0. The sole respiratory lipoquinone was ubiquinone-10. The main polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid, an unidentified aminophospholipid and three unidentified phospholipids. Based on physiological, chemotaxonomic and phylogenetic analysis, strain PrR001Tis suggested as a novel species in the genusDefluviimonas, for which the nameDefluviimonas pyrenivoranssp. nov. is proposed. The type strain ofDefluviimonas pyrenivoransis PrR001T(=CICC 24263T=KCTC 62192T).
