The key to taking the measure of biodiversity lies in a downward adjustment of scale. . .Most of the Earth’s largest species—mammals, birds, and trees—have been seen and documented. But microwildernesses exist in a handful of soil or aqueous si

In the photosynthetic bacteria, as in other N2-fixing bacteria, two main enzymes are involved in H2 metabolism: nitrogenase, which catalyses the photoproduction of H2, and a membrane-bound (NiFe) hydrogenase, which functions as an H2-uptake enzyme. T

In some Rhodospirillaceae, the primary light-harvesting (LH I) antenna absorbs near-infrared light around 870 nm, whereas LH II (holochrome B800-860) has a major absorption band between 850 and 860 nm (B860) and a minor absorbancy around 800 nm (B800

Rhodospirillum rubrum mutant C grew photosynthetically in the light and produced copious amounts of H2. During light-growth mutant C produced 7.9mmol of H2 in medium with 9mmol of Na-pyruvate per mg protein. When parent strain R. rubrum S1 was grown

Strain 1, a bacterium which grew methylotrophically with carbon monoxide under anaerobic, dark conditions, was identified as a member of Rhodopseudomonas gelatinosa (Molisch) van Niel on the basis of its cell morphology, ultra-structure, pigment cont

When Rhodospirillum rubrum mutant C was first exposed to radiant energy after long-term anaerobic dark growth, the cells often exhibited a diauxic growth response. This happened with pyruvate in the medium and when cultures were exposed to a less-tha

Photoheterotrophically grown Rhodospirillum rubrum mutant C oxidized 3,3'-diaminobenzidine (DAB) by two aerobic reactions. One reaction was light dependent. The other respiratory reaction occurred in the dark and could be inhibited by 0.1 M KCN. DAB

Rhodospirillum rubrum grew anaerobically in darkness and fermented sodium pyruvate by a pyruvate formate-lyase reaction. During 30 min of anaerobic dark or light incubation with sodium pyrivate, crude extracts from fermentatively grown cells produced

Photosynthesizing cells of Rhodospirillum rubrum mutant C underwent adaptation for growth in low-light conditions. During adaptation there was a transitory increase in the generation time and the bacteriochlorophyll a content of the cells.
