微生物聚酯的合成和应用研究进展

Progress on the biosynthesis and application of microbial polyesters

微生物聚酯是由发酵技术生产、具有生物降解性的热塑性高分子材料。本文介绍了３－羟基丁酯均聚物（ＰＨＢ）和共聚物的基本结构、生物降解性能、生物合成及其应用研究的进展。

Microbial polyesters,produced through fermentation,is a new type of biopolymers withthermoplastic and biodegradation characteristics. In this paper,the basic structure,properties of biodegra-dation,biosyntheses and progress on research and applications of the homo-and co-polymer of 3-hy-droxy-butyl are described.
