Strain CMAA 1215(T), a Gram-reaction-negative, aerobic, catalase positive, polarly flagellated, motile, rod-shaped (0.5-0.8 x 1.3-1.9 A mu m) bacterium, was isolated from mangrove sediments, Canan,ia Island, Brazil. Analysis of the 16S rRNA gene sequences showed that strain CMAA 1215(T) forms a distinct phyletic line within the Pseudomonas putida subclade, being closely related to P. plecoglossicida ATCC 700383(T), P. monteilii NBRC 103158(T), and P. taiwanensis BCRC 17751(T) of sequence similarity of 98.86, 98.73, and 98.71%, respectively. Genomic comparisons of the strain CMAA 1215(T) with its closest phylogenetic type strains using average nucleotide index (ANI) and DNA:DNA relatedness approaches revealed 84.3-85.3% and 56.0-63.0%, respectively. A multilocus 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 support the assignment of CMAA 1215(T) to the genus Pseudomonas, representing a novel species. The name Pseudomonas aestus sp.nov. is proposed, with CMAA 1215(T) (=NRRL B-653100(T) = CBMAI 1962(T)) as the type strain. (AU)
