ABSTRACT
Effect of CTAB addition on the accumulation of microbial transglutaminase (MTG) with Streptomyces hygroscopicus was investigated. The results showed that the addition of CTAB enhanced MTG accumulation, and the optimal addition time and concentration of CTAB were 32 h and 1%. The maximum MTG activity in the culture broth was 5.04 u/mL and increased by 21.8% compared with the control. With the addition of CTAB, pro-MTG was activated to become MTG. CTAB could enhance the production of pro-MTG by relieving the product inhibition, and the accumulation of MTG was improved.
