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
