    Abstract:
    An aerobic, Gram-stain-negative, rod-shaped bacterium with a single polar flagellum, designated CC-OPY-1(T), was isolated from an oil-contaminated site in Taiwan. CC-OPY-1(T) produces siderophores, and can grow at temperatures of 25-37 °C and pH 5.0-9.0 and tolerate <5 % (w/v) NaCl. The 16S rRNA gene sequence analysis of CC-OPY-1(T) showed high pairwise sequence similarity to Pseudomonas alcaligenes BCRC 11893(T) (97.1 %), Pseudomonas. alcaliphila DSM 17744(T) (97.1 %), Pseudomonas tuomuerensis JCM 14085(T) (97.1 %), Pseudomonas toyotomiensis JCM 15604(T) (96.9 %) and lower sequence similarity to remaining species of the genus Pseudomonas. The phylogenetic trees reconstructed based on gyrB and rpoB gene sequences supported the classification of CC-OPY-1(T) as a novel member of the genus Pseudomonas. The predominant quinone system of strain CC-OPY-1T was ubiquinone (Q-9) and the DNA G+C content was 68.4 ± 0.3 mol%. The major fatty acids were C12 : 0, C16 : 0, C17 : 0 cyclo and summed features 3 and 8 consisting of C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c, respectively. The major polar lipids were phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), phosphatidylcholine (PC) and two unknown phospholipids (PL1-2). Due to distinct phylogenetic, phenotypic and chemotaxonomic features, CC-OPY-1(T) is proposed to represent a novel species within the genus Pseudomonas for which the name Pseudomonas sagittaria sp. nov. is proposed. The type strain is CC-OPY-1(T) ( = BCRC 80399(T) = JCM 18195(T)).
