Effect of Ultraviolet-B (280 to 320 nm) Radiation on Blue-Green Algae (Cyanobacteria), Possible Biological Indicators of Stratospheric Ozone Depletion.
The effect of ultraviolet-B (280 to 320 nm) irradiation on physiological activities of Anabaena flos-aquae and the water fern Azolla caroliniana has been studied under conditions where lethal effectsExpand
Direct demonstration of ammonia as an intermediate in nitrogen fixation by Azotobacter.
When Azotobcter vinelandii is grown on molecular nitrogen, it utilizes ammonia without enzymatic adaptation. Furthermore, the distribution of N15 in amino acids derived from cell hydrolysates is theExpand

  • 1 October 1962
Chromatophores isolated from photosynthetic bacteria contain a disulfide-bonded repeating antigenic substructure that is serologically specific and present on the cell particles only duringExpand
The Relationship Between Photosynthesis and Nitrogen Fixation.
Involvement of Photosystem II in the ammonia metabolism of a heterotrophic cyanobacterium
Abstract Herbicides that bind specifically to Photosystem II greatly increased ammonia liberation by a heterotrophic cyanobacterium incubated with methionine sulfoximine anaerobically in light.Expand
Composition of the photoactive subcellular particles from Chromatium.
Abstract The gross composition and some of the chemical components of the chromatophores isolated by differential centrifugation from extracts of the purple sulfur bacterium Chromatium , strain D,Expand
Photophosphorylation by subcellular particles from Chromatium.
Abstract A light-induced phosphorylation of adenosine diphosphate has been studied, using pigmented particles derived from sonic extracts of the obligately-anaerobic photosynthetic purple sulfurExpand
Immunochemical studies on the photoactive subcellular particles from Chromatium.
Abstract Specific antisera have been prepared in rabbits by injection of pigmented particles isolated by differential centrifugation from extracts of the photosynthetic bacterium Chromatium . TheseExpand

Antisera were prepared in rabbits by injection of purified chromatophore preparations from Rhodospirillum rubrum grown anaerobically in the light. The antisera contained antibody which precipitatedExpand
Inhibition of succinate oxidation and transport into mitochondria by metal‐complexing agents
Studies of the permeability properties of mitochondria indicate that the cristae membrane contains several systems used for the transport of substrates into and from the matrix space, including aExpand
