Resumen:
Nine Gram-negative, rod-shaped, non-spore-forming isolates with identical or very similar repetitive-sequence-based PCR profiles were recovered from an evaporative lagoon in Mexico. Two strains, designated 1N(T) and 3N, had virtually identical 16S rRNA gene sequences and, on the basis of these sequences, were identified as members of the genus Pseudomonas, with Pseudomonas peli R-20805(T) as the closest relative. All nine isolates had practically identical whole-cell protein profiles. The major fatty acids [C(16:0), C(18:1)omega 7c and summed feature a (C(16:1) omega 7 and/or C(16:1) omega 6c)] of strains 1N(T) and 3N supported their affiliation with the genus Pseudomonas. The DNA-DNA reassociation values with respect to P. peli LMG 23201(T) and other closely related Pseudomonas species were <15 %. Physiological and biochemical tests allowed phenotypic differentiation of the strains analysed, including strain 1 IN, from the five phylogenetically closest Pseudomonas species. On the basi
