Non-osmotic effects of external sugars on the cell water content and transport of cations across the plasmalemma inHydrodictyon reticulatum

Saccharides added to the cultivation medium influence the properties of the cell wall of the strictly autotrophic green algaHydrodictyon reticulatum, most probably in such a way that they interfere with the processes of growth and repair of microfibrils. Natural monosaccharides (glucose, fructose, g...

Summary:Saccharides added to the cultivation medium influence the properties of the cell wall of the strictly autotrophic green algaHydrodictyon reticulatum, most probably in such a way that they interfere with the processes of growth and repair of microfibrils. Natural monosaccharides (glucose, fructose, galactose, mannose, sucrose, cellobiose, raffinose) reduce the cell water content, increase the intracellular concentration mostly of both potassium and sodium cations and reduce the ohmic resistance of the cell membrane.
