| Popis: | Three facultative anaerobe mesophilic bacteria were isolated from marine sediment collected off Niigata, Japan. Sequencing of complete 16S ribosomal DNA revealed 99% homology with Shewanella algae, Pseudomonas pseudoalcaligenes, and P. stutzeri. Phylogenetic analyses suggest novel strain status thus new strains were designated as S. algae strain Hiro-1, P. pseudoalcaligenes strain Hiro-2, and P. stutzeri strain Hiro-3. Minimum inhibitory concentration assays using increasing concentrations of Na2TeO3 revealed resistance of S. algae strain Hiro-1 at 15 mM, and P. pseudoalcaligenes strain Hiro-2 and P. stutzeri strain Hiro-3 both showed resistance at 4 mM. Transmission electron microscopy revealed intracellular aggregation of metallic tellurium nanorods with a minimum unit size of 60-nm nanoparticle. |
