The researches on polyhydroxyalkanoates (PHAs) microbiological synthesis from food wastes were summarized and analyzed. The structure and properties of polyhydroxyalkanoates, microorganisms of PHAs synthesis and PHAs microbiological synthesis using food wastes were discribed in this paper. The prospects of future research in special microbial screening of PHAs synthesis and comprehensive utiliza- tion of activated sludge and food wastes were proposed to researchers as a reference.%针对利用食品废弃物合成可生物降解塑料——聚羟基烷酸酯（PHAs）方面的研究,通过分析近年国内外文献,介绍了PHAs的结构与性能、合成PHAs的微生物、利用食品废弃物合成PHAs等方面的研究现状,展望了合成PHAs微生物筛选和使用、活性污泥混合菌群与食品废弃物合成PHAs的资源化利用前景,以期对相关人员的研究工作提供参考.
