Simple stain of rhodospirillum rubrum
WebbWhen R. rubrum was cultivated anaerobically in the dark synthesis of BChl and thylakoid morphogenesis was dependent on the substrate. The bacteria synthesized only traces of BChl with acetate, succinate, or malate as a substrate. With malate a few thylakoid vesicles were produced in addition. WebbThe citrate synthase from R. rubrum was activated by KCl (6-fold at 0.1 M KCl) and, less effectively, by NaCl and NH4Cl. Its molecular weight was about 300,000. The enzyme was strongly inhibited by NADH, and this inhibition was counteracted by AMP.

Rhodospirillum rubrum is a photosynthetic bacterium and possesses special organelles called bacteriochlorophylls that absorb light between 800 and 925 nanometers. Rhodospirillum rubrum grows anaerobically when light is available and aerobically in the dark. The organism was originally isolated from mud and stagnant water.
Webb1 juli 2011 · Strain S1 T (= ATCC 11170 = DSM 467) is the neotype strain of the species Rhodospirillum rubrum, which is the type species of the genus Rhodospirillum. The genus name is derived from the ancient Greek term rhodon, meaning rose, and the Latin spira, meaning coil. Rubrum is Latin for red. WebbRhodospirillum rubrum (strain ATCC 11170 / NCIB 8255) is a Gram-negative, motile and spiral-shaped bacterium. It is able to grow under a broad range of conditions including aerobiosis and anaerobiosis. It can use fermentation or photosynthesis for producing energy when it grows anaerobically. It is able to grow on CO as sole source of energy.
WebbRhodospirillum rubrum is the type strain for the Rhodospirillaceae and has been, and continues to be, the subject of a substantial amount of physiological and genetic analysis.
