Abstract:
The present study describes the isolation of microorganisms capable of producing alpha-pinene from beta-pinene. 24 (15 fungi, 9 bacteria) microorganisms were isolated from galbanum, gum and soil, were screened for their ability to transform beta-pinene to alpha-pinene. Biotransformation products were extracted with n-hexan and analyzed by gas chromatography. One microorganism (bacterial strain) were found. The biotransformation medium involved, phosphate buffer pH 6, 100 microL beta-pinene, 1 g biomass of microorganism, 37 degrees C, 150 rpm and 22 h. The experiments were performed in conical flasks. The optimum cell growth were obtained when 30 g L(-1) glycerin applied. The optimum conversion beta-pinene to alpha-pinene was obtained when 20 g L(-1) glycerin applied as carbon source for bacterial strain.
