Expression of phaPor phaC alone or with another gene enhanced PHBHHx content up to 64%, cell dry weight(CDW) as much as 4.4 g L-1 and PHBHHx concentration to 2.7 g L-1 after 48 h in shake flaskculture.

• 只要重组菌有外源phaC 或者phaP 的表达；经过48 h 的摇瓶实验就细胞干重均可提高；最高至4.；4 g L-1；PHBHHx 最高积累至64 wt%25；PHBHHx 产量提高到2
