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.
