The Influence of Buffer Capacity of Dried Corn Steep Liquor Powder on the Fermentation of Bacterial Cellulose

LU Min;L Xuan;GUAN Xiao-hui;School of Chemical Engineering,Northeast Dianli University;  
The fermentation process of bacterial cellulose(BC) was studied in this paper by use of dried corn steep liquor powder as a single nitrogen source and Gluconacetobacter xylinus Gyll as a strain. This paper concentrated on the buffering capacity of dried corn steep liquor powder,changes in the pH-value and BC output. The results shows that after dissolving dried corn steep liquor powder in aqueous solutions and fermentation medium respectively and additive amount exceeding 50.0 g/L and 40.0 g/L, the buffer index(β) is more than 0.02. This illustrates system has better buffering capacity. And in the fermentation process, system can keep the pH-value at suitable scope of growth for Gluconacetobacter xylinus Gyll that can help increase the BC output.
