TL;DR: 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, according to their phenotypic characteristics, antibiotic susceptibility profiles, and fatty acids patterns.

TL;DR: Two bacterial strains, KMM 227T and 231T, were isolated from seawater samples collected from the north-western Pacific Ocean at a depth of 4000-5000 m and were characterized using polyphasic taxonomy, indicating that the two strains formed a distinct lineage within a clade containing the genera Alteromonas, Colwellia and Pseudoalteromonas in the gamma-Proteobacteria.

TL;DR: Principal coordinate analysis of fatty acid data have shown that the majority of the type strains and marine species, identified as Alteromonas sp.

TL;DR: DNA-DNA hybridization experiments revealed that the levels of relatedness between the DNA of the strain studied and DNAs of type strains of the species that clustered together ranged from 19 to 35%, and that the DNA-DNA homology between [P. aurantia] NCIMB 2033 and other phylogenetically and/or phenotypically similar type strains ranged from 32 to 52%.

TL;DR: Four species of bivalves from Vostok Bay were analyzed and it was confirmed that all molluscs with chemoautotrophic symbionts yielded nonmethylene-interrupted dienoic fatty acids, which must be considered the reliable biochemical evidence for the existence of symbiosis of the animal with chemosymbiotic bacteria.
