摘要/Abstract

摘要： 通过向以水稀释3倍体积的玉米芯水解液中加入膨润土无机凝胶,利用木醋杆菌原位发酵技术制得细菌纤维素/膨润土无机凝胶复合材料,并对其微观形貌进行表征,对发酵液的pH、产量、糖转化率和持水量进行了测试。结果表明:扫描电子显微镜照片显示膨润土无机凝胶吸附于细菌纤维素的表面和孔内;发酵液的pH随膨润土无机凝胶添加量的增大而上升并最终保持在8左右;产量随膨润土无机凝胶添加量的增大而增大;糖转化率随膨润土无机凝胶添加量的增大而减小;复合材料的持水量随着膨润土无机凝胶添加量的增大而减小。

Abstract: Bio-based bacterial cellulose (BC)/inorganic gel of bentonite (IGB) composite was prepared by adding IGB into corncob hydrolysate,which was pre-diluted three multiples with water,and then in situ fermented by Acetobacter xylinum.Micro-morphological characteristics of the product were characterized.Yield and water holding capacity of the product,inversion of the saccharides as well as pH value of the fermentation broth were examined.The SEM images showed that the IGB is adsorbed on the surface of the BC as well as in the pores of the BC.Moreover,with the increase of addition amount of IGB,the pH value of the fermentation broth raises and finally maintains around 8,yield of the product increases,while inversion of the saccharides and water holding capacity of the product decreases.

Key words: bacterial cellulose, inorganic gel of bentonite, modification, composite
