Optimization of Molasses and Soybean Meal Content to Enhance Tetramethylpyrazine Yield by Bacillus sp. TTMP20

Yujia Li,
Shanling Gan,
Lirong Luo
et al.

Abstract: Microbial fermentation for the production of tetramethylpyrazine (TTMP) is considered to be the most promising method, and the development of a cheap fermentation substrate is of great importance for large-scale TTMP production. In this study, inexpensive by-products from the food industry, i.e., molasses and soybean meal (instead of glucose and tryptone), were used as substrates for TTMP fermentation. The pretreatment of soybean meal was explored in order to achieve a better fermentation effect. The contents … Show more

“…RSM is a sophisticated method to optimize the process. In our previous studies, RSM was successfully used to optimize the processes including the removal of heavy metal chromium, carotenoid extraction, and culture medium composition. The solid yield and lignin removal were greatly affected by the NaOH concentration and time in this study (Figures and ). The optimal NaOH pretreatment conditions were a NaOH concentration of 1%, a time of 60 min, and a solid-to-liquid ratio of 1:15.…”
