摘　　要：聚羟基脂肪酸酯(PHAs)是由微生物合成的天然高分子材料。由于对二氧化碳排放的收紧和对环境问题的日益关注,绿色可降解塑料PHAs的生产和应用成为研究热点。其良好的生物可降解性和生物相容性,使得其成为替代化石原料塑料的最佳选择,也受到了高端医用材料制造商的青睐。介绍了以廉价底物为碳源生产PHA的方法及其在塑料包装及生物医学方面的应用。Polyhydroxyalkanoate(PHAs) is a natural polymer material synthesized by microorganisms. Due to the tightening of carbon dioxide emission and the increasing attention to environmental issues, the production and application of green degradable plastics PHAs has become a research hotspot. Its good biodegradability and biocompatibility make it the best alternative to fossil raw plastics, and it is also favored by high-end medical materials manufacturers. In this paper, the production method of PHAs with cheap substrate as carbon source and its application in plastic packaging and biomedicine were introduced.
