Oceanobacillus-like bacterium isolated from Vyhna travertine spring.

During characterization of autochthonic Vyhna travertine source microflora, several bacterial strains were isolated and characterised. Isolate T6, a halotolerant, moderately alkaliphilic and thermophilic bacterial isolate, was further characterised based on physiological, microbiological and biochemical tests and phylogenetic 16S rRNA analysis. On the basis of the results obtained, the T6 isolate should be placed in the genus Oceanobacillus, and it is probably a prototype of a novel bacterial species. Characterization of the T6 isolate broadens our knowledge on variability of halophilic bacteria of Oceanobacillus genus and expands data on travertine-associated bacterial communities.
