Photobioreactor for cultivation and real-time, in-situ measurement of O-2 and CO2 exchange rates, growth dynamics, and of chlorophyll fluorescence emission of photoautotrophic microorganisms

Original language description

A detailed knowledge about the dynamics of phytoplanktonic photosynthesis and respiration is crucial for the determination of primary productivity in oceans as well as for biotechnology. The dynamics are best studied in photobioreactors that are able tosimulate natural conditions. We demonstrate performance of a newly designed laboratory photobioreactor that meets these needs, with a study of green alga Scenedesmusquadricauda. The instrument monitored the culture growth by measuring the optical densities at 735 and 680 nm and by measuring several fluorescence parameters. These widely used but rather indirect estimates were confronted with direct measurements of O2 quantum yields. The CO2 fluxes in and out of the culture media as well as the dissolvedCO2 in algal suspension were also recorded. The experiments demonstrated potential of the photobioreactor to reveal minute modulations in gas exchange rates as well as to yield data for planning of large scale photobioreactors. A detailed
