可降解塑料—多聚羟基丁酸的高密度发酵研究

Study on Synthesis of Degradable Plastic PHA by High Cell Density Fermentation

对本实验室选育的合成多聚羟基丁酸的优良菌株华癸根瘤菌 M0 2进行分批发酵和补料分批发酵研究 ,细胞浓度可以达到 62 .3 g/ L,产物 PHB含量为 45 .2 g/ L。

The experiment of batch fermentation and fed-batch fermentation was carried out by the strain of rhizobium huakuii M02 which has been isolated by our laboratory.The results showed that the final dry cell concentration of 62.3 g/L and PHB concentration of 45.2 g/L was obtained.In contrast to results which were obtained the further experiment can be carried out.
