报告摘要：
天然多糖作为食品和药品中最丰富的成分，是人类碳水化合物和膳食纤维的主要来源。多糖除了营养功能外，还具有显著的生物活性和特殊的保健功效。多糖被广泛认为是保护和改善健康、预防和治疗常见疾病的最有前途的营养产品和治疗候选物。近20-30年来，人们尤其是中国学者对天然活性多糖的研究表呈现出指数级增长趋势。本报告将介绍生物活性多糖的当前研究开发的现状、趋势和前景，特别讨论了多糖在肠道微生物群的益生作用机制。在此基础上，详细介绍了本研究组对药用真菌Cs-HK1菌丝体发酵胞外多糖的益生活性和治疗功效的研究进展。
Polysaccharides represent one of the most abundant components in many food and medicinal products. In addition to their common functions as the major sources of carbohydrates and dietary fibres for human nutrition, many polysaccharides have special health benefits and notable bioactivities. Over the last 2-3 decades, there has been an exponential increase of research in bioactive natural polysaccharides, especially in China. Natural polysaccharides have been widely recognized as the most promising nutraceutical and therapeutic candidates for promotion and protection of human health and for prevention, and treatment of prevalent human diseases. This presentation is to give my views on current trends and promising opportunities in the research and development of bioactive polysaccharides, and the role of gut microbiota in the mechanisms of action for their health benefits. It will further illustrate the approaches, directions, and findings of our recent studies on the prebiotic properties and therapeutic functions of exopolysaccharides (EPS) produced by mycelial fermentation of a medicinal fungus Cs-HK1.
