More Information
Summary:The invention relates to the field of organic waste resource utilization, and discloses a method for producing polyhydroxyalkanoate through organic waste fermentation, polyhydroxyalkanoate comprises polyhydroxybutyrate and polyhydroxyvalerate, and fermentation substrates comprise kitchen waste, vinasse, activated sludge and a mixture thereof. The method comprises the following steps: mixing kitchen waste with vinasse, performing hot alkali pretreatment, inoculating anaerobic sludge to produce acid, and then filtering; performing sequencing batch aerobic domestication on the activated sludge containing the PHAs synthetic bacteria; taking the filtered clear liquid after acid production in the step a, then inoculating the activated sludge domesticated in the step b, carrying out continuous aeration aerobic fermentation, and obtaining PHAs by adopting an ethylenediamine tetraacetic acid-lauryl sodium sulfate method. According to the scheme, the adopted raw materials are common organic wastes which are large in am
