Construction of functional oligosaccbaride production system from biomass using various enzyme and physical treatment

生物质被认为是地球上最丰富、最清洁的资源，也是我们未来生活的支柱。我们提出了两种从废弃生物质中生产新材料和能源的方法：(1)生物量扩大形成；(2)功能性低聚糖生产。生物质膨胀形成很容易从玉米花或各种植物纤维素中产生。其压缩应力与反应温度有关，且随反应温度的升高而增大。几乎生物质的主要成分是纤维素（50%），这种成分将用于医药中间体生产或清洁能源“生物乙醇”的生产。超临界和亚临界水在不需要任何化学试剂的情况下，对纤维素的降解和生产各种低聚糖具有良好的催化作用。确定反应条件如下：纤维素的降解始于170℃（最适温度为240℃），温度越高，糖环就越开裂，产生醛分子。

Biomass is expected that it is the most abundant and clean sources in the earth, and also will be supported our life in the future. We proposed two kinds of methods to produce the new material and the energy source from the waste biomass as follows ; (1) Biomass expanded formation, and (2) functional oligosaccharide production. Biomass expanded formation is easily produced from scob or various plant celluloses. Its compressed stress of then is dependant on the reaction temperature, and this valve is increased with rising of reaction temperature.The main content of almost biomass is cellulose (50 %), and this component will be useful for medicine intermediate production or clean energy "bio ethanol" production. Supercritical and subcritical water are functioned as a, good catalysis for degradation of cellulose and production various oligosaccharide without any chemical reagents. The reaction condition was identified as follows ; the degradation of cellulose was started at 170 ℃ (the optimal temperature is 240 ℃), and the more over temperature induced cracking of saccharide ring and produced aldehyde molecules.
