Results of a study on the solution behaviour of the cell-wall polysaccharide named ulvan obtained from hot water extraction of a flour of Ulva 'rigida' are reported. In particular the spectroscopic properties and ion binding capacity of this charged polysaccharide were studied by circular dichroism and isothermal microcalorimetric titrations in order to gain information on the potential exploitation of this low cost biomass. A marked tendency of this polysaccharide to uptake water was evidenced by studying the proton spin-lattice relaxation times of the solvent, T1, embedded in this highly charged polysaccharide.
报道了一项关于从石莼(Ulva 'rigida')面粉热水提取物中获得的名为岩藻依聚糖的细胞壁多糖溶液行为的研究结果。特别地,通过圆二色性和等温微量热滴定法研究了这种带电多糖的光谱性质和离子结合能力,以便获取有关这种低成本生物质潜在利用的信息。通过研究嵌入这种高电荷多糖中的溶剂的质子自旋 - 晶格弛豫时间T1,证明了这种多糖具有明显的吸水趋势。
