Resum

A total of twenty aerobic endospore-forming bacilli, isolated from marine invertebrates and sea water of different areas of the Pacific Ocean, were taxonomically characterized. Most of the bacilli (11 strains) of marine origin belonged to the species Bacillus subtilis, according to their phenotypic characteristics, antibiotic susceptibility profiles, and fatty acids patterns. A group of four alkaliphilic strains formed a separate cluster that was tentatively classified as B. horti. One isolate, KMM 1717, associated with a sponge from the Coral Sea was identified as B. pumilus. Two strains, Bacillus KMM 1916 and KMM 1918, showed antibiotic sensitivity profiles similar to B. licheniformis, but they had a distinct fatty acid composition and peculiar phenotypic traits. The taxonomic affiliation of KMM 1810 and KMM 1763 remained unclear since their fatty acid composition and antibiotic sensitivity patterns were not resembled with none of these obtained for Bacillus strains.
