一般描述

纤维素,由通过β-1,4键连接的葡萄糖单元组成的均聚物。它们通过分子间和分子内氢键以及范德华力发生强烈附着,从而使得微纤维一起形成纤维。它们平行地分布在相邻葡聚糖链的末端。 纤维素广泛用作TLC中的吸附剂。

应用

纤维素可用于通过X射线衍射(XRD)图和固态13C核磁共振光谱测定结晶度指数。
用于分区色谱的高纯度纤维素粉末。

In anaerobic environments rich in decaying plant material, the decomposition of cellulose is brought about by complex communities of interacting microorganisms. Because the substrate, cellulose, is insoluble, bacterial and fungal degradation occurs exocellularly, either in association with the outer cell
