Description	In algae possessing lichens, polyols serve as energy-storing compounds. They are also osmotically-active compounds that increase lichen resistance to low and freezing temperatures. Natural levels of polyols in lichens are species-specific. They vary within 1.4-8.8 mg.g-1 DW (ribitol), 0.4-29.0 mg.g-1 (mannitol). We investigated natural and experimentally-affected contents of polyols and non-structural saccharides (NSS). Ribitol, mannitol, arabitol and NSS were HPLC-evaluated before and after the experimental treatments: in-vitro exposition of thalli to additional ribitol (32, 50 mM for 168 h at +5, 0, -5 deg C). Initial values were 2.6, 4.1 mg.g-1 DW (ribitol, mannitol). Addition of ribitol led to increased levels of mannitol (at all temperatures), while ribitol, arabitol and fructose showed either no or insignificant change. In control and ribitol-treated lichens, lowest mannitol content was found at -5 deg C. The results were attibuted to altered utilization of polyols at freezing temperature.
