Synopsis
Although the European food supply seems one of the most secure and safest in the world at present, the focus on developments in food quality, nutrition and health during ECBA’s symposium and workshop revealed a n...

Chapter and Conference Paper
Working Group I
In Europe the positive links between basic research, the application of scientific knowledge for economic purposes and for the health of citizens have to be developed. This realisation can be justified especi...

Working Group II
The rural environment, at least as far as this has been understood in the European tradition, is neither a wild space in which nomadic encampments are scattered, nor an ephemeral aggregate of highly industrial...

O-Dealkylation of coumarin and resorufin ethers by unicellular green algae: kinetic properties of Chlorella fusca and Chlorella sorokiniana
O-Dealkylations of resorufin and coumarin ethers, mediated by microsomal cytochrome P450 monooxygenases from animals, plants and microorganisms, are shown here to be performed also by in...

P-31 NMR saturation transfer experiments in Chlamydomonas reinhardtii : evidence for the NMR visibility of chloroplastidic Pi
ATP synthesis and consumption in respiring cells of the green alga Chlamydomonas reinhardtii were measured with 31P in vivo NMR saturation transfer experiments to determine the intracellular compartmentation of i...

The dependence of the cytoplasmic pH in aerobic and anaerobic cells of the green algae Chlorella fusca and Chlorella vulgaris on the pH of the medium as determined by 31P in vivo NMR spectroscopy
The pH in the cytoplasm of aerobic and anaerobic cells of the green algae Chlorella fusca and Chlorella vulgaris was determined in dependence on the pH of the external medium, which was varied between pH 3 and pH...

P-31 in-vivo NMR investigation on the function of polyphosphates as phosphate-and energysource during the regreening of the green alga Chlorella fusca
The green alga Chlorella fusca accumulates polyphosphates under conditions of nitrogen starvation while deassembling the photosynthetic apparatus. The polyphosphate content of cells regreening after resupply with...

On the Protective Role of Carotenoids in the Ps I Reaction Centre and LHCI Complexes of The Thylakoid Membrane
The molecular arrangement of chlorophylls and carotenoids with proteins and lipids in the thylakoid membrane of chloroplasts determines their function in light harvesting and energy transfer reactions. Caroten...

The significance of hydrogenase activity for the energy metabolism of green algae: anaerobiosis favours ATP synthesis in cells of Chlorella with active hydrogenase
In cells of the green alga Chlorella fusca, which contain active hydrogenase(s), the concentration of ATP, NADH and NADPH were measured during a 5 h period of anaerobiosis in the dark and upon subsequent illumina...

Respirational activity of Chlorella fusca monitored by in vivo P-31 NMR
Energy metabolism during dark respiration of the green alga Chlorella fusca was investigated by 31P NMR spectroscopy. The kinetics of the transition from anaerobic to aerobic conditions (and vice versa) was follo...
