The optimal conditions for extracting IDF with lactobacillus and facultative thermophile were: inoculants size 6%, the ratios between the two reagents 1:2, fermentation temperature 37℃, fermentation time 15h; fermentation temperature and fermentation time were significant effecters to the IDF content(P.05); inoculums size and the ratio between the two reagents were of little significance.

5用微生物发酵法提取水不溶性膳食纤维的最佳工艺条件是：接种量为6%，两菌比为1：2，发酵温度为37℃，发酵时间为15h。发酵温度和发酵时间对产品膳食纤维含量的影响显著(P.05)，接种量和两菌比的影响不显著。

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.
