摘要 考察添加不同浓度羧甲基纤维素钠(CMC-Na)对Acetobacter xylinum NUST4.1在摇瓶和机械搅拌发酵罐中产细菌纤维素(BC)的影响。结果发现:添加0.06% CMC-Na能有效解决发酵罐中严重结团和菌株逐级放大后生产稳定性差的2大难题,而且能显著提高纤维素产量,优化发酵罐基本工艺后能获得3.35g/L干纤维素,是基础培养的3.1倍。 The effect of sodium carboxymethyl cellulose(CMC-Na) on bacterial cellulose(BC) produced by Acetobacter xylinum NUST4.1 in the shake flask and stirred tank fermenter was studied.Results showed:adding 0.06% CMC-Na could resolve two problems to serious clump forming and low produc- tion stability,and could significantly increase cellulose yield,after optimizing basic technology,dry cellulose could reached 3.35g·L^(-1) which was 3.1 times of foundation medium.
