| phylogeny and evolution of the family ectothiorhodospiraceae based on comparison of 16s rrna, cbbl and nifh gene sequences. | the occurrence of genes encoding nitrogenase and ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) was investigated in the members of the family ectothiorhodospiraceae. this family forms a separate phylogenetic lineage within the gammaproteobacteria according to 16s rrna gene sequence analysis and mostly includes photo- and chemoautotrophic halophilic and haloalkaliphilic bacteria. the cbbl gene encoding the large subunit of 'green-like' form i rubisco was found in all strains, except th ... | 2007 | 17911316 |
| arhodomonas aquaeolei gen. nov., sp. nov., an aerobic, halophilic bacterium isolated from a subterranean brine. | arhodomonas aquaeolei gen. nov., sp. nov., isolated from a petroleum reservoir production fluid, is described. the single isolate was an obligately halophilic, aerobic, gram-negative, oval rod-shaped bacterium that was actively motile by means of a single polar flagellum. it was catalase and oxidase positive. the isolate had a specific requirement for nacl; growth occurred at nacl concentrations between 6 and 20%, and optimal growth occurred in the presence of 15% nacl. this species metabolized ... | 1993 | 8347510 |
