Posted by UATEC - Unidade de Transferência de TecnologiaResponsive · Patents for licensing · Portugal

Summary of the technology

This invention presents the following advantages relatively to existing technologies:
•it allows the evaluation of the photosynthetic performance and the physiological state of photosynthetic organisms
•the measurement of light-response curves of chlorophyll a fluorescence made of non-sequential and independent measurements
•very fast light curve generation
•possibility to define and control with a high degree of flexibility the range of light intensity and color applied to the samples.

Description of the technology

A group of researchers of a Portuguese university has developed a method for the measurement of the in vivo emission of chlorophyll a fluorescence by photosynthetic organisms. This invention allows to measure the photosynthetic activity through the generation of ‘light-response curves’, a common way of evaluating the physiological state of plants, algae or other photosynthetic organisms. The advantages of the method, relatively to the existing solutions, consist in the possibility of obtaining light curves made of independent observations, measured in a non-sequential way, in a much faster way than with any of the existing methods. The university searches for companies interested in developing electronic equipment dedicated to the implementation of the method.

Specifications

The method is based on the combination of i) projection in the sample of a group of spatially-separated light beams, of different intensity or quality, using a digitally-controlled projector, and ii) measurement of the chlorophyll a fluorescence emitted as a response to each light beam, fluorometer capable of registering fluorescence images. The method permits a better and much faster evaluation of the physiological state of photosynthetic organisms like plants or algae, to predict their response in terms of photosynthetic efficiency to different lighting conditions, the identification and selection of varieties of organisms with superior photosynthetic performance, or the detection and quantification of effects of toxic compounds in the productivity of plant or algae.

Main advantages of its use

  • • it allows the evaluation of the photosynthetic performance and the physiological state of photosynthetic organisms

  • • the measurement of light-response curves of chlorophyll a fluorescence made of non-sequential and independent measurements
  • • very fast light curve generation

Applications

  • The present invention has applications in fluorometry imaging systems, namely in research and other applications.
