Better results could be obtained, For 40 hours fermentation, cell dry weight and PHB concentration reached 32.7 g · L-1 and 21.4g · L-1 respectively.The synthesis of Poly (β-Hydroxybutyrate-co-β-Hydroxyvalerate) by the strain G-IIIy from different precusor was studied. It was found that the strain G-IIIy could accumulate PHBV with sucrose as carbon source and propionic acid or valeric acid as precursor . In 2L self-controlled fermentor, the dry cell weight, PHBV concentration and PHBV content reached 35.8g·L-1, 22.6g·L-1 and 38.4% respectively in the case of fermentation for 42 hours and the propionic acid as precursor.
