Mediosalinum living at a moderate salinity in the medium moderate halophile.
Rhodospirillum sp. Dundas Ian 1984-07-01 000000 A new species of halophilic photosynthetic bacteria Rhodospirillum salinarum has been isolated and described. Q3B and Rhodospirillaceae sp. 1Bacterial Discovery Laboratory Centre for Environment Institute of Science and Technology JNT University Kukatpally Hyderabad India.
Based on the morphological physiological chemotaxonomical and molecular evidence strain JA318T is significantly different from the type strains of species of the genus Rhodospirillum of the family Rhodospirillaceae and it is proposed that the strain be classified as a representative of a novel species for which the name Rhodospirillum oryzae sp. Sodomense pertaining to the Sea of Sodom the Talmudic name for the Dead Sea. The genus Rhodospirillum comprises nine species with out as described previously Srinivas et al 2007.
Nov a halophilic photosynthetic bacterium isolated from a Portuguese saltern Rhodospirillum salinarum sp. Nov a phototrophic alphaproteobacterium requiring a reduced sulfur source for growth. A novel non-sulfur purple photosynthetic bacterium designated Rhodospirillum centenum was isolated from an enrichment culture designed to favor growth of anoxygenic photosynthetic N 2 -fixing bacteria.
Q3C was found to contain highest carotenoid content up to 56 mgg 1. Based on 16S rRNA gene sequence analysis and morphological and physiological characteristics strain JA143T was significantly different from the other two recognized species of the genus Rhodospirillum and represents a novel species for which the name Rhodospirillum sulfurexigens sp.

Such diverse bacteria can be useful tools for bioremediation purposes. Members of the α-proteobacterial group which includes photosynthetic bacteria of the Rhodobacter and Rhodopseudomonas and Rhodospirillum genera as well as the nonphotosynthetic genera Agrobacterium Rhizobium and Bradyrhizobium and all eukaryotic organisms that do not contain chloroplasts animals yeasts fungi form ALA by condensation of succinyl-coenzyme A with glycine. A novel non-sulfur purple photosynthetic bacterium designated Rhodospirillum centenum was isolated from an enrichment culture designed to favor growth of anoxygenic photosynthetic N2-fixing bacteria.
If the species was not widely studied the American Type Culture Collection ATCC was used to determine the optimal pH for storage. Under anaerobic conditions the isolates were able to respire arsenic in the presence of lactate citrate and oxalate. Growth was best at 12 NaCl with only weak growth occurring at 6 or 21 NaCl.
Rhodospirillum sodomense Mack et al. 16S rRNA gene for the type strain. Centenum grows optimally at 4042 C and has the capacity to produce cytoplasmic R bodies refractile structures not observed hitherto in.
Rhodospirillum salinarum sp. If two far ranges of pH were determined the average was taken. Differs from the rhodospirilla described so far by its small size ultrastructure and physiological and biochemical characteristics.
Q3C were also found to produce hydrogen gas. The new organism isolated from watersediment of the Dead Sea was vibrio-shaped and an obligate halophile. See also Global Catalogue of Microorganisms DSI ATCC 51195 DSM 9895.
16S rRNA validly published names. Rhodospirillum mediosalinum Kompantseva and Gorlenko 1984. Six of these have been reclassified gene sequences were aligned using the CLUSTAL_X program in other genera Imhoff et al 1998 and Rhodospirillum Thompson et al 1997 and the alignment was corrected centenum is a synonym of Rhodocista.
Centenum grows optimally at 40-42 degrees C and has the capacity to produce cytoplasmic R bodi. Nov a halophilic photosynthetic bacterium isolated from a. Rhodospirillum sodomense Mack et al.
Sodomense pertaining to the Sea of Sodom the Talmudic name for the Dead Sea. The optimal pH at which this species grows. See detailed strain information at.
