Pseudomonas indica sp. nov., a novel butane-utilizing species.
The taxonomic position of two butane-utilizing bacteria was studied using a polyphasic approach. Biochemical and physiological characteristics indicated these to be members of the genus Pseudomonas, showing more similarity to Pseudomonas mendocina than to any other species. The major fatty acids found in these two strains also pointed to their similarity to P. mendocina. On the other hand, DNA-DNA hybridization studies with seven related Pseudomonas species belonging to the gamma-Proteobacteria and the deltaTm values of reassociated molecules clearly showed that these two strains do not belong to any of the seven species tested. The 16S rRNA gene was sequenced and compared with the sequences available in the GenBank database. Phylogenetic analysis using the region covering positions 31-1488 (Escherichia coli numbering) confirmed these observations and placed these two strains as members of the authentic Pseudomonas, but not in any existing species of the genus. On the basis of biochemical characteristics, fatty acid profiles, DNA-DNA reassociation and deltaTm values, as well as 16S rRNA gene sequence analyses, these two isolates were shown to belong to one species but to have characteristics distinct from those of validly described species of Pseudomonas (sensu stricto). These strains, therefore, should be recognized as a novel species, for which the name Pseudomonas indica sp. nov. is proposed. The type strain is strain IMT37T (= MTCC 3713T = DSM 14015T).
