제목 Solvent Production with High Productivity Using Clostridium acetobutylicum
초록 The aim of the present study was to establish a continuous fermentation process for an engineered C. acetobutylicum strain which can result in high ABE productivities. In the present work, high cell density was achieved by applying the multiple cell recycling bioreactor (MCRB). Experiment was started with batch mode which was converted to continuous mode when the residual glucose concentration in medium reached to approximately 20 g/l. Continuous fermentation was started with 0.7 h-1 dilution rate. The maximum obtained ABE productivities was 15.7 g l−1 h−1 respectively. Further optimization of the fermentation parameters and dilution rates are in progress.
