摘　　要：聚羟基脂肪酸酯(PHAs)是微生物在不平衡生长状态下作为胞内碳源和能源被储存的一种高分子聚合物,可以用一系列的可再生原料和生物方法来生产,具有生物降解性和生物相容性等特点,可以代替某些传统的石化塑料,应用前景广阔。目前,工业上生产PHAs主要利用野生型和重组型微生物的发酵来进行,而混合培养和转基因植物生产PHAs也因其成本低廉等优点受到越来越广泛的关注。文中主要对近年来生物合成聚羟基脂肪酸酯(PHAs)的研究进展进行总结,以期为聚羟基脂肪酸酯的工业化生产及进一步的开发利用提供依据。Polyhyroxyalkanotes （PHAs） are synthesized by numerous bacteria as an intracellular carbon and energy storage compound under nutrient-limiting conditions with excess carbon. PHAs are biodegradable and biocompatible polyesters that can potentially replace certain plas- tics derived from petroleum, it can be usedin many fields. PHAs can be produced using a combination of renewable feedstocks and biological methods. Native and recombinant microorganisms have been generally used for making PHAs via fermentation processes, but the use of mixed cultures and transgenic plants as a cheaper method to produce PHAs has gained much attention in recent years. The research advances in bio- synthetic of polyhyroxyalkanotes were summarized, which can provide basis for industrialization production and further development and utiliza- tion of polyhyroxyalkanotes.
