Method for producing PHA (polyhydroxyalkanoate) by using halomonas

The invention relates to the technical field of microbial fermentation, in particular to a method for producing PHA by using halomonas. A method for obtaining PHA through continuous fermentation of microorganisms is easy to pollute by infectious microbes, and pure culture is difficult to guarantee. In order to solve the problems, the invention provides the method for producing the PHA by using the halomonas, a microorganism used for fermentation is the halomonas, the halomonas can adapt to a culture medium with high salt concentration, the high salt environment prevents the culture medium from being polluted by infectious microbes in the air, and pure culture of the halomonas is ensured. Besides, according to the three-section type microorganism continuous fermentation technology, the proliferation process of halomonas thalli mainly occurs in the fermentation tank 1, the process of transformation from thalli proliferation to PHA synthesis mainly occurs in the fermentation tank 2, the process of rapid synthesi
