The type, initial feeding time and concentration of precursor for HV unit formation had great effects on PHBV production in shake flasks. Propionate was selected as the better precursor for HV fraction than valerate after comprehensive survey of these two precursors. The suitable PHBV shaking-flask culture conditions were obtained through the analysis of PHBV fermentation process, the investigation of several factors by using RSA method and the fed-batch experiments. Cell dry weight, PHBV content, PHBV concentration, HV fraction and yield coefficient of HV unit to propionate were 27. 7g/L, 80.7%, 22. 4g/L, 16. 1mol% and 0.50g/g, respectively.

在共聚物PHBV的摇瓶发酵过程中，PHBV中HV组分形成的前体物质的种类、初始加入时间以及加入量是影响PHBV发酵过程的重要因素；在综合比较丙酸和戊酸这两种前体的基础上，选择丙酸作为HV组分合成前体较适宜；通过对PHBV发酵过程曲线分析、影响PHBV发酵指标的各因素的响应面分析以及摇瓶发酵补料试验，得到了较适宜的PHBV摇瓶发酵补料条件，在此条件下，细胞干重、PHBV含量、PHBV浓度、HV组分含量和HV组分对丙酸的产率系数可分别达到27.7g/L、80.7％、22.4g/L、16.1mo1％和
