Beschreibung
Zusammenfassung:	The invention provides an improved method for producing polyhydroxyalkanoates (PHA) with microbes. The method includes the following step: adding acetic acid, acetate, acetic ester or other acetic acid derivatives to a base medium containing a carbon source and for synthesizing PHA from microbes; and preferably adding acetic acid or acetate. The method can be used to increase the yield of the PHApolymer synthesized from microbes and/or to control the monomer ratio in the PHA copolymer product. 本发明提供一种改进的微生物生产聚羟基脂肪酸酯(PHA)的方法，所述方法包括向包含碳源以供微生物合成PHA的基础培养基中添加乙酸、乙酸盐、乙酸酯或其他的乙酸衍生物；优选添加乙酸或乙酸盐。该方法可以用于提高微生物合成PHA聚合物的产量和/或控制PHA共聚物产物中的单体比例。
