Title: Optimization on Fermentation Conditions of Butanol from Sweet Potato
Abstract: Fermentation conditions of Clostridium acetobutylicumto produce butanol by using sweet potato as raw material were optimized.Effects of the concentration of sweet potato,the type and concentration of additional nitrogen source,and the dosage of sodium acetate on fermentation were investigated.The results showed that,when the concentration of sweet potato was 8%,the concentration of ammonium acetate was 2%(C/N value was 20),the dosage of sodium acetate was 0.4%,the content of butanol in fermentation broth reached14.410mg·mL-1,which obviously higher than that of non-optimization process.The study lays the foundation for industrialization of butanol production by fermentation.
