摘要

Dynamics model for polysaccharide (HNCVP) extraction process from Nostoc commune Vauch was established. The process was fitted with the second Fick’s law, and exhibited a spontaneous and exothermic process. A maximal HNCVP yield was obtained under temperature of 363.15 K, extraction time of 150 min and solid-liquid ratio of 1:50 g/mL. The apparent viscosity of HNCVP affected significantly by pH and the type and intensity of ions, and increased significantly with the increase of Na+ and K+ concentration, while significant decreased after the addition of Ca2+ and Zn2+. In addition, HNCVP can inhibit the proliferation of Bovine Viral Diarrhea Virus (BVDV) by interference with 5’ UTR gene synthesis, and protection cells growth by regulating the relatively expression of IRF-1 and IRF-3 in Madin-Darby bovine kidney cells, where interferon maybe activated for virus elimination and defense. These results presented the potential of HNCVP as a functional additive in the food and pharmaceutical industries.
