Deep dehydration of antarctic lichen Leptogium puberulum Hue observed by NMR and sorption isotherm

Hydration kinetics, sorption isotherm, and proton free induction decays are measured for Leptogium puberulum Hue thalli hydrated from gaseous phase. Very tightly, tightly and loosely bound water fraction are distinguished. The hydration dependence of mobile NMR signal component is non-linear and fit...

Description
Summary:Hydration kinetics, sorption isotherm, and proton free induction decays are measured for Leptogium puberulum Hue thalli hydrated from gaseous phase. Very tightly, tightly and loosely bound water fraction are distinguished. The hydration dependence of mobile NMR signal component is non-linear and fitted well by rational function, which suggest the presence of water soluble solid (presumably carbohydrate) fraction in thallus structures of L. puberulum.
