  • Method for detecting photosynthesis inhibition
    Patent number: 7333195
    Abstract: This invention relates to a method for detecting the photosynthesis-inhibitory activity of substances by providing cells or cell parts with an intact photosystem, introducing the cells or cell parts into a planar layer, applying the test substance to the planar layer or into the planar layer, excitation of the luminescence of the cells or cell parts in the planar layer by an excitation light source, measuring the luminescence of the cells or the cell parts in the planar layer by means of a detector, and associating the detector signal with the degree of photosynthesis inhibition.

  • Analytical process for testing mixtures for toxic constituents
    Patent number: 6238928
    Abstract: The mixture to be tested for toxic components is first separated into fractions by chromatography. The separated fractions are then contacted with luminescent microorganisms in the chromatographic system itself and the toxicity of the fractions is determined by measurement of the bioluminescence. The chromatographic separation may be carried out either by thin layer chromatography or by column liquid chromatography.
