Defined medium allowing maximal growth of Rhodomicrobium vannielii

Carotenoids of Rhodomicrobium Vannielii.

The relationship of the anaerobic, photoheterotrophic bacterium Rhodomicrobium vannielii to other photosynthetic bacteria is difficult to assess in view of its complex morphological characteristics (Duchow and Douglas, J. Bacteriol. 58: 409, 1949). A detailed examination of its carotenoid constitution was carried out to establish more clearly its relationship to other photosynthetic bacteria. A...

Hydrogen metabolism by Rhodomicrobium vannielii.

Under appropriate cultural conditions, cell suspensions of Rhodomicrobium vannielii effect two distinct photoreactions involving molecular hydrogen: (i) the photoreduction of carbon dioxide, and (ii) the photoproduction of hydrogen.

Fine Structure of the Photosynthetic Bacterium Rhodomicrobium Vannielii

The fine structure of the photosynthetic bacterium Rhodomicrobium vannielii was studied by the ultra thin sectioning technique. Cells were fixed in buffered osmium tetroxide and embedded in Epoxy resin. The feature most common to nearly all cells was an array of intracellular membranes situated in a concentric manner at the periphery of the cell. The membranes were mostly paired and quite often...

Phototrophic oxidation of ferrous iron by a Rhodomicrobium vannielii strain.

Oxidation of ferrous iron was studied with the anaerobic phototrophic bacterial strain BS-1. Based on morphology, substrate utilization patterns, arrangement of intracytoplasmic membranes and the in vivo absorption spectrum, this strain was assigned to the known species Rhodomicrobium vannielii. Also, the type strain of this species oxidized ferrous iron in the light. Phototrophic growth of str...
