厨余垃圾生物合成聚羟基脂肪酸酯研究进展

基于利用厨余垃圾作为合成挥发性脂肪酸（VFAs）的原始基质,既可以增加厨余垃圾资源化利用新途径,又可以降低聚羟基脂肪酸酯（PHA）合成成本,有利于厨余垃圾合成PHA产业化发展的优势,概述了PHA的应用领域和类型,总结了厨余垃圾合成PHA工艺路线和PHA前体物（VFAs）合成阶段与PHA 合成阶段的内在合成机制,重点汇总了利用厨余垃圾合成VFAs过程和利用VFAs合成PHA过程的重要工艺参数。最后,对厨余垃圾合成PHA 研究方向进行了展望。

Research progress in biosynthesis of polyhydroxyalkanoates from kitchen waste

The development of PHA industrialization was promoted through using the kitchen waste as feedstock to produce VFAs. This not only increase a new pathway for kitchen waste resource utilization, but also significantly reducing the cost of PHA products. This paper introduced the application fields and product types of PHA and summarized the technological process of PHA production using the kitchen waste. The mechanisms for the kitchen waste anaerobic acidification and PHA production were also analyzed. Furthermore, the effects of technological factors on the acidification phase of kitchen waste and the PHA enrichment and accumulation phase were discussed systematically. Finally, some outlooks on the development of PHA production from the kitchen waste were provided.
