MicroProtein Technologies Inc. has developed the MPTxpress high-yield, low‑cost, recombinant Escherichia coli manufacturing platform. Rather than using liquid culture media within stirred bioreactors, the system uses trays filled with semisolid (gelled) culture media overlaid with or without a permeable membrane on which the E. coli is cultured. Compared with conventional liquid fermentation platforms, the MPTxpress system reduces the number of steps in up- and downstream processing and required infrastructure, significantly improves yields, and lowers costs. It provides simplicity for mixing…
