    Notes: Abstract During adaptation of photoautotrophically growing fresh water cyanobacterium Anacystis nidulans to high salinity the cells showed a pronounced increase of proton-sodium antiporter activity, and of cytochrome c oxidase in isolated and purified plasma membrane. At the same time the concentrations of plasma membrane-bound EDTA-resistant copper and iron (determined by inductively coupled plasma atomic emission spectrometry) rose proportionately, accompanied by an increase in whole cell respiration. In plasma membranes from salt adapted cells lipid/protein ratios were markedly higher than in control cells, levels of esterified saturated and long-chain fatty acids being significantly higher than the respective levels of unsaturated and short-chain fatty acids which explains the higher lipid-phase transition temperatures derived from Arrhenius plots. Immunoblotting of the membrane proteins with antisera raised against the cytochrome c oxidases from Paracoccus denitrificans and A. nidulans gave two cross-reacting bands with apparent molecular weights around 50000 and 30000 (subunits I and II, respectively) which were more pronounced in plasma membranes from salt adapted cells when compared to control cells. The protein pattern of plasma membranes from salt adapted cells also showed the appearance of bands at apparent molecular weights of 44000–48000 and 54000–56000 which might stem from the proton/sodium-antiporter in this membrane.

    Notes: Die ausgeführten Versuche sollten zur Beantwortung der Frage beitragen, ob das Altern der Mineralwässer eine besondere Eigenschaft der natürlichen Quellen ist, oder ob sich die katalytischen Eigenschaften derselben auch an künstlichen Lösungen reproduzieren lassen.Die beschriebene Versuchsanordnung gestattete es, das Vermögen des Kochbrunnens Wasserstoffsuperoxydlösungen zu zersetzen, ohne wesentliche Beeinflussung durch Nebenreaktionen zu verfolgen.
