摘　　要：聚β-羟基丁酸（PHB）是许多原核微生物在碳、氮营养失衡的情况下作为能量和碳源储藏在生物体内的一类热塑性聚酯。作为完全可生物降解材料，PHB越来越引起人们的关注。有力文章主要阐述了国内外PHB合成方法、性能改良、降解等方面的进展，并对其发展前景作出展望。PHB is a kind of polyester stored in organism body as carbon source and energy source, when prokaryotes is in imbalance of carbon and nitrogen nourishment. As a kind of degradable microorganiam materical, PHB has attracted more and moreattention from people. This article mainly introduced advances in biosynthesis, modification and degradability of PHB at home and abroad, and pointed that PHB had better development prospect.
