| Abstract: | Microfiltration membrane bioreactor with stirred backflush operation was designed for biotransformation using intact cells. Experiment of production of L aspartic acid from furmarate by Escherichia coli having aspartase was carried out to investigate the optimal pore size of membrane and cell concentration in the reactor. The performance of biotransformation using intact cells in the membrane reactor and using immobilized cells in the packed bed reactor were compared. |
