초록

Poly-$\beta$-hydroxybutyrate(PHB) was biosynthesized using Alcaligenes sp. FL-027. Alcaligenes sp. FL-027 was cultivated by fed-batch methods, in order to promote cell growth and PHB accumulation with carbon source. The cells were first grown at 3$0^{\circ}C$ on the fermentor. The structure of biosynthesized PHB is investigated by the NMR, IR. The crystalline portions were identified through the use of DSC and X-ray diffractometer. The melting point was about 16$0^{\circ}C$ and the diffraction peaks of (020) and (110) were shown at 13$^{\circ}$ and 17$^{\circ}$, respectively.
