	Rhodospirillum rubrum
		Rhodospirillum is a genus of photosynthetic bacteria of the family Rhodospirillaceae.
		Their cells are generally spiral-shaped, polarly flagellated and contain vesicular, lamellar of stacked photosynthetic membranes (Singleton and Sainbury).
		The accuracy of the contents of this report is not guaranteed and it is recommended that you seek additional sources of information to verify the contents.

	Organic waste processing method, and uses thereof - Patent 6077548
		The method of claim 8, wherein said heterotrophic or photoheterotrophic bacteria are selected from the group consisting of bacteria of the germs Rhodobacter, bacteria of the genus Rhodospirillum, and mixtures thereof.
		In a still further preferred variation of the treatment method of the invention, the heterotrophic or photoheterotrophic bacteria which produce the edible biomass are from the Rhodospirillaceae family.
		Preferred bacteria of the Rhodospirillaceae family are bacteria from the genus Rhodobacter such as Rhodobacter capsulatus and/or from the genus Rhodospirillum such as Rhodospirillum rubrum.

	DSMZ, Medium 27: RHODOSPIRILLACEAE MEDIUM (modified)
		Incubate in the light using a tungsten lamp.
		For brown and other oxygen sensitive Rhodospirillaceae add 300 mg of L-cysteine (0.03% end concentration) to the boiling medium and readjust the pH to 6.8 or to the prepared medium in bottles inject neutralized sulfide solution (0.005 to 0.01% end concentration).
		The medium has been modified according to reference 3365.

		The purple non-sulfur bacteria are a family (Rhodospirillaceae) of phototrophic bacteria that photosynthesize using bacteriochlorophylls a and b in anoxic environments, such as the bottom mud of ponds and other stagnant water, although they are able to survive in air.
		The reducing agent involved is hydrogen rather than water, so oxygen is not produced.

	BioMed Central \| Full text \| Widespread presence of "bacterial-like" PPP phosphatases in eukaryotes
		These enzymes are more closely related to bacterial PPP phosphatases than to the known eukaryotic members of the family.
		One group, found exclusively in land plants, is most closely related to PPP phosphatases from some α-Proteobacteria, including Rhizobiales, Rhodobacterales and Rhodospirillaceae.
		The presence of signal peptides and targeting sequences was analyzed using TargetP [63] at the the Centre for Biological Sequence Analysis, Technical University of Denmark [64].

	Bacteria.
		Some photosynthetic bacteria use simple organic compounds such as acetate, formate and methanol as a sole carbon source rather than fixing carbon dioxide.
		These bacteria are photoorganotrophs, and are exemplified by the purple non-sulphur bacteria such as the Rhodospirillaceae when grown anaerobically in the light.
		Rhodospirillaceae cannot grow anaerobically unless they are illuminated.

		No special conditions are required for incubating the column with the exception that it should be placed where it will receive adequate daylight or artificial light to support growth of a variety of phototrophic bacteria.
		These include the cyanobacteria (blue-green algae), and the purple (Chromatiaceae) and green (Chlorobiaceae) sulfur bacteria as well as the purple nonsulfur bacteria (Rhodospirillaceae).
		After about 3-6 weeks, depending on the soil, amendments, and incubation conditions, the columns develop a characteristic appearance.

	Purple Bacteria
		A comparable rise in redox poise of the electron transfer chains occured on the cyanobacterial branch.
		Purple bacteria are distinguished into the Chromataceae (formerly named Thiorhodaceae) and the Rhodospirillaceae (formerly called Athiorhodaceae).
		Purple bacteria perform an anoxygenic type II- photosynthesis which was until recently considered to be switched on exclusively under anaerobic conditions.

		One oddity of Misnomera is its ability to photosynthesize both oxygenically and anoxygenically.
		Misnomera possesses a similar photosynthetic system similar to the Rhodospirillaceae family of purple bacteria.
		For photosynthesis, it has both thylakoids (disc-like photosynthesizers) with chlorophyll a and with bacteriochlorophyll a.

	SPRI 2006 Brazil Abstracts of presentations
		It became possible by developing new light scattering material especially to maintain the optical intensity of the red wavelength band which photosynthesis bacteria use, and a near-infrared domain on a high level.
		In laboratory scale experiments, red non-sulfur photosynthesis bacteria (from the Rhodospirillaceae Family) were chosen as photosynthesis bacteria, and the possibility of starting the improvement in hydrogen gas manufacturing efficiency and utilization of a system was examined.
		Although the hydrogen gas obtained by experiment was 10 - 40% of theoretical, the validity of the photoactivating method was confirmed by the experiment when compared with the conventional lagooning method.
