摘要: 本实验研究了少动鞘脂单胞菌S1胞外多糖的脱乙酰基的反应条件,用神经网络方法对反应条件建模。研究了胞外多糖的乳化性、溶解性和流变性。结果表明少动鞘脂单胞菌S1胞外多糖具有良好增稠作用,与黄原胶相似。

关键词: 胞外多糖, 乳化性, 溶解性, 流变性

Abstract: Exopolysaccharides of Sphingomonas paucimobilis S1 was deacetylated. Emulsifying activity, dissolution and rheology of exopolysaccharides was studied. This kind of exopolysaccharides had a property of forming viscous solution similar to xanthan gum and can be acted as viscosifier.

Key words: exopolysaccharides, emulsify, dissolution, rheology
