系统地总结了混合菌群利用有机废水提供的底物合成PHA的相关研究进展，一般来说，混合微生物群在好氧瞬时供料和厌氧／好氧活性污泥工艺这两种模式下合成PHA．国内研究着重于探索反应器的运行条件，包括驯化过程和积累过程，以及从混合菌群中分离可合成PHA的微生物等．国外研究着重于探索各种可用作碳源的有机废水，分离鉴定各种能够大量合成PHA的微生物，以及不同种类底物对PHA产量和单体组成的影响．基于一些技术性突破，PHA合成模式可扩大规模应用于工业生产．根据现有合成方法进展，提出发展方向是分离鉴定出更多的合成PHA含量高的微生物，透彻分析其在PHA驯化积累过程中的作用；同时使废水中各类有机物比例均衡，最后进行条件优化，实现PHA产量最大化．

This paper systematically summarizes the research progress of which mixed bacteria produce PHA using substrate from organic wastewater .Generally speaking , mixed bacteria can produce PHA by two ways, AN/AE technology and ADF technology .Domestic researches emphasized the operating condi-tions in the reactor including the domestication and accumulation .Besides , the researchers extracted the microorganism producing PHA .Foreign researches emphasized the identification of different kinds of mi-croorganism for keeping PHA .What's more, they studied the influence that different substrates pose to PHA yield and composition and looked for more effective substrate from organic wastewater .Thanks to some technical breakthrough , PHA producing pattern can apply to industrial production .According to the current producing methods , this paper proposes that more reliable microorganism with high PHA storage should be identified and researches should go deep into the role of specific bacteria .Meanwhile , nutrition from the substrate needs to be balanced .Then it should optimize the operating conditions so as to achieve PHA production maximization .
