Studies on Biosynthesis of P(HB-HH)at the Level of Substrate Regulation and Fermentation
He Dongliang (Department of Environment Engineering,North China University,Taiyuan 030008,China)
The experiment of synthesis poly-hydroxy-alkanotes(PHAs)at the level of substrate regulation was carried out by the strain of sinfrddi Sf-008. In the experiment of flask,the concentration of caprate and time of adding caprate in culture medium were studies,at the same time the content and the rate of monomer of PHAs were mensurated by GC. The results show that optimal concentation of caprate was 2.5 mmol/OD·L and optimal time of adding caprate was at the period of telphase of logarithm.
