Conteúdo: | Strain CMAA ­ 1215T, a Gram-reaction-nega- tive, aerobic, catalase positive, polarly flagellated, motile, rod-shaped (0.5-0.8 × 1.3-1.9 -m) bacterium, was iso- lated from mangrove sediments, Cananéia Island, Brazil. Analysis of the 16S rRNA gene sequences showed that strain CMAA ­1215T forms a distinct phyletic line within the Pseudomonas putida subclade, being closely related to P. plecoglossicida ATCC 7 ­ 00383T, P. monteilii NBRC ­103158T, and P. taiwanensis BCRC ­17751T of sequence similarity of 98.86, 98.73, and 98.71%, respectively. Genomic comparisons of the strain CMAA 1215T ­ with its closest phylogenetic type strains using average nucleo- tide index (ANI) and DNA:DNA relatedness approaches revealed 84.3-85.3% and 56.0-63.0%, respectively. A mul- tilocus sequence analysis (MLSA) performed concatenating 16S rRNA, gyrB and rpoB gene sequences from the novel species was related with Pseudomonas putida subcluster and formed a new phylogenetic lineage. The phenotypic, physiological, biochemical, and genetic characteristics sup- port the assignment of CMAA ­1215T to the genus Pseu- domonas, representing a novel species. The name Pseu- domonas aestus sp.nov. is proposed, with CMAA 1 ­ 215T (=NRRL B-653100T = CBMAI ­1962T) as the type strain.
