| 摘 要： | 聚羟基烷酯(PHAs)作为一种可以完全生物降解的合成塑料替代品而受到越来越多的关注。好氧瞬时供料法由于高的PHAs合成能力及可利用混合菌群(如活性污泥)和有机废弃物合成PHAs显著降低成本而成为目前最具应用前景的PHAs合成技术。文章阐明了好氧瞬时供料法合成PHAs的代谢机制及工艺过程,并就采用该方法合成PHAs的过程中诸多的影响因素进行分析和探讨。

| Abstract: | In the latest decades,polyhydroxyalkanoates(PHAs) have attracted increasing interest as an alternative to petroleum-derived plastics for being completely biodegradable.Among the methods,aerobic dynamic feeding(ADF) approach by activated sludge is the most promising because of high PHA accumulation,meanwhile,could substantially decrease the cost of PHA and increase their market potential for using activated sludge and renewable sources obtained from waste organic carbon.Metabolisms and production process of aerobic transient feeding(ADF) approach were reviewed,analyzing the affective factors. |
