The in vivo substitution of Mg2+ in chlorophyll by heavy metals is an important damage mechanism in heavy metal-stressed plants that leads to an inhibition of photosynthesis. In photosynthetic organisms with LHC II antennae, the in vivo substitution

A detailed knowledge about the dynamics of phytoplanktonic photosynthesis and respiration is crucial for the determination of primary productivity in open oceans as well as for biotechnological applications. The dynamics are best studied in photobior

The increases in atmospheric pCO₂ over the last century are accompanied by higher concentrations of CO₂(aq) in the surface oceans. This acidification of the surface ocean is expected to influence aquatic primary productivity and may also affect c

Chlorophyll fluorescence imaging is a non-invasive method to monitor the metabolic state of photosynthetic organisms. We used spatially resolved (imaging) microscopic measurements of chlorophyll fluorescence kinetics to follow the fate of individual

A microscope for imaging of chlorophyll fluorescence kinetics was equipped with a chamber that allows the growth of an immobilised population of algae and their study under well-defined conditions. Single cells of the chlorococcal alga Scenedesmus qu

A new chamber was developed for a simultaneous measurement of fluorescence kinetics and oxygen exchange in filamentous and thallous algae as well as in small leaves of water plants. Algal filaments or thalli are kept by a stainless grid close to the

The targets of heavy metal (here Cu 2 + and Zn 2 + ) attack on the photosynthetic apparatus of algae belonging to different phyla were investigated. Experiments with the green alga Scenedesmus quadricauda confirmed previous findings that according to

The efficiency in selective extraction of photosystem (PS) 2 oxygen evolving complexes was compared among seven detergents. These were applied to thylakoid membranes of the thermophilic cyanobacterium Synechococcus elongatus. Used were five non-ionic

Oxygen-evolving photosystem II particles (DT 20) isolated from pea chloroplasts by digitonin-Triton X-100 fractionation were photoinhibited with 150 W·m−2 white light, at 20°C under three conditions: aerobic, anaerobic and strongly reducing (Eh p
