A Gram-negative, strictly aerobic bacterial strain was isolated from asymptomatic leaf tissue of a wild yam plant. Optimal growth was observed at 28 °C and pH 7, and catalase and oxidase activities were detected. Polyphasic taxonomic and comparative genomics revealed that strain LMG 33091 T represents a novel species of Pseudomonas . The nearest phylogenetic neighbours of strain LMG 33091 T were Pseudomonas putida NBRC 14164 T (with 99.79 % 16S rRNA sequence identity), Pseudomonas alkylphenolica KL28 T (99.28 %) and Pseudomonas asplenii (99.07 %) ATCC 23835 T . MALDI-TOF MS analysis yielded distinct profiles for strain LMG 33091 T and the nearest phylogenetic neighbours. Average nucleotide identity analyses between the whole genome sequence of strain LMG 33091 T and of the type strains of its nearest-neighbour taxa yielded values below the species delineation threshold and thus confirmed that the strain represented a novel Pseudomonas species, for which we propose the name Pseudomonas fortuita sp. nov., with strain LMG 33091 T (=GMI12077 T = CFBP 9143 T ) as the type strain.
