| 目的 综述可降解包装材料聚羟基烷酸酯（Polyhydroxyalkanoates，简称PHAs或PHA）的主要合成工艺、影响PHA产率的因素及其在包装工业领域上的应用研究进展。方法 通过对国内外的研究现状和研究成果进行分析总结，介绍PHA的主要合成工艺，微生物法合成PHA产量的影响因素及PHA在包装方面的应用。结果 PHA合成工艺、碳源种类和浓度、氮磷源浓度、pH值、溶解氧浓度和温度对合成PHA的产量有很大影响，其中碳源种类不同还会使形成PHA的单体及单体在PHA中的比例不同，形成具有不同性质的PHA。PHA因其性能的多样性而广泛应用于包装领域。结论 优化PHA的合成工艺及影响因素，能有效提高PHA产量或降低PHA生产成本。目前，以真实废弃物为底物的活性污泥系统生产PHA的研究还不够深入，由于PHA作为可降解的包装材料在包装领域具有显著的发展前景，因此，优化PHA合成工艺和影响因素是今后值得关注的重点方向。 |

| The work aims to summarize the research progress of the main synthetic technology of degradable packaging material Polyhydroxyalkanoates (PHAs or PHA), the factors affecting the yield of PHA and the application in packaging industry of PHA. Based on the analysis and summary of the research status and achievements at home and abroad, the main synthetic process of PHA, the influencing factors on the yield of PHA by microbial synthesis and the application of PHA in packaging were introduced. PHA synthesis process, types and concentration of carbon sources, concentration of nitrogen and phosphorus sources, pH value, concentration of dissolved oxygen and temperature had a great impact on the yield of PHA. Different types of carbon sources also made the monomers of PHA different, and the proportion of monomers in PHA was different which formed PHA with different properties. Due to the diversity of PHA performance, it could be widely applied to packaging. Optimizing the synthesis process and influencing factors of PHA can effectively increase the yield of PHA or reduce the production cost of PHA. However, the research on the production of PHA by activated sludge system with real waste as substrate is not deep enough. As a degradable packaging material, PHA has significant development prospects in the field of packaging. Therefore, optimizing the synthesis process and influencing factors of PHA is the focus of attention in the future. |
