«The State of Water in the Zoogley of the Tibetan Milk Fungus and the Effect of Liquid Polydimethylsiloxane on It»
1083–1092 (2020)

PACS numbers: 76.60.-k, 81.07.Nb, 82.39.Rt, 82.56.-b, 87.80.Lg, 92.20.jb,

The structure of the hydration layers of water bonded in the symbiont Tibetan kefir grains with a different degree of its hydration (h, g/g) in the air medium and in a contact with polydimethylsiloxane PDMS-1000, whose molecules can penetrate into the intercellular gaps of zoogloea, reducing cellĖcell interactions, is studied by the low-temperature \(^1\)H NMR spectroscopy. As shown, the maximum hydration symbiont is h=32 g/g (dry matter), and the water is in the form of polyasociates (clusters or domains) formed by the weakly and strongly associated water.

Keywords: Tibetan kefir grains, low-temperature \(^1\)H NMR spectroscopy, strongly and weakly bound water, silicon oil
