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

An primary optimization for medium composition in shake flask showed the best carbon source, nitrogen source , culture volume , incubating quantity and pH after having completed studying the relation between thalli form,zymotic condition and metabolized yields .

通过摇瓶培养，研究发酵条件对菌体形态、产物产量的影响，初步优化了发酵培养基组成，确定了最佳碳源、氮源、装液量、接种量、pH等。

Compared with alcoholmeter method, its measurement results were more accurate. The alcohol content measurement results by chemical oxidation and by international density flask method were the same.

在这两个方法中，密度瓶法作为经典的分析方法，结果准确，但是，20℃的恒温条件不易控制，这就势必造成一定的分析误差；而酒精计法虽然具有操作简便快速，但由于酒精计精度较差和人为因素，导致误差较大。

The results showed that the optimal carbon sourceand nitrogen source were amidulin,CaCO_3 and yeast.The optimization pH 7.0～8.0,cultural temperature:30—32℃,and germ Q6 was cultured for 48h inbroad-openning flask with 20% volume medium.

结果表明，在起始pH值7.0～8.0，接种量为5％以上，培养基装量为广口三角瓶体积的20％以下，培养温度30—32℃，振荡培养48h时Q6发酵产物的抑菌活性最强。
