摘要

聚羟基脂肪酸酯(PHA)是原核微生物在碳、氮营养失衡的情况下，作为碳源和能源贮存而合成的一类热塑性聚酯。它除了具有与化学合成高分子相似的性质外，还具有一般化学合成高分子没有的性质，如生物可降解性、生物相容性、压电性、光学活性等特殊性质，因而具有广阔的应用前景。国内外已对PHA 进行了大量的研究。本文主要综述了近二、三年来国内外对PHA 生物合成的研究进展。

Abstract

Polyhydroalkanoates (PHA) are a class of thermoplastic polyesters formed as carbon and energy reserve materials by various bacteria under nutrient-limited conditions in the presence of excess carbon source. PHA possess not only mechanical properties similar to synthetic polymers

but some features such as biodegrability

biocompatibility

piezoelectricity and optical activity

leading to its great potential for applications in many fields.Numerous studies have been done on PHA.This paper mainly reviews the progress in biosynthesis of PHA in recent years.
