生物技术降解海带岩藻聚糖硫酸酯分子研究现状

Research Study on Biodegradation of Seaweed Fucoglycan Sulfate

天然海带硫酸多糖分子量很大,不易被人体吸收利用,而低分子量海带岩藻聚糖硫酸酯具有多种生物活性。生物酶或微生物作为一种生命活性物质,对生物大分子降解选择性好、副产物少,为降解海带多糖提供了有效技术手段。分析了国内外利用生物酶或微生物降解多糖的技术现状和可行性,并对生物降解海带硫酸多糖前景进行了探讨。

Natural kelp polysaccharide sulfate has a large molecular weight,which is not easy to be absorbed and used by human body,while low molecular weight kelp fucoglycan sulfate has a variety of biological activities.As a kind of life active substance,biological enzymes or microorganisms have few by-products for the degradation of biological macromolecules,so it can be concluded that biodegradation technology can be an effective means for the degradation of kelp.In this paper,the present situation and feasibility of biodegradation of polysaccharide by enzyme or microorganism were summarized and analyzed.
