The use of commercially available ferulic acid (FA) as a precursor for vanillin production is costly. The utilization of agro-waste as a starting material provides an alternative to obtain FA at a low cost and establish an economically profitable production system. In this work, optimization of ultrasound-assisted extraction conditions for releasing FA from corn cobs using alkaline treatment was conducted. Further, bioconversion of FA from the crude hydrolysate of corn cobs to vanillin using Amycolatopsis thermoflava was performed.

在营养限制和还原糖控制下，通过 Amycolatopsis thermoflava 增强阿魏酸从玉米芯碱性水解产物到香兰素的生物转化

使用市售的阿魏酸 (FA) 作为香兰素生产的前体是昂贵的。利用农业废弃物作为起始材料提供了一种以低成本获得 FA 并建立经济上有利可图的生产系统的替代方案。在这项工作中，对使用碱处理从玉米芯中释放 FA 的超声辅助提取条件进行了优化。此外，使用Amycolatopsis thermoflava将 FA 从玉米芯的粗水解产物生物转化为香兰素。
