Protocell Flow Reactors for Enzyme and Whole‐Cell Mediated Biocatalysis
Abstract: The design and construction of continuous flow biochemical reactors comprising immobilized biocatalysts have generated great interest in the efficient synthesis of value‐added chemicals. Living cells use compartmentalization and reaction‐diffusion processes for spatiotemporal regulation of biocatalytic reactions, and implementing these strategies into continuous flow reactors can offer new opportunities in reactor design and application. Herein, the fabrication of protocell‐based continuous flow reactors for enzyme and whole‐cell mediated biocatalysis is demonstrated. Semipermeable membranized coacervate vesicles are employed as model protocells that spontaneously sequester enzymes or accumulate living bacteria to produce embodied microreactors capable of single‐ or multiple‐step catalytic reactions. By packing millions of the enzyme/bacteria‐containing coacervate vesicles in a glass column, a facile, cost‐effective, and modular methodology capable of performing oxidoreductase, peroxidase and lipolytic reactions, enzyme‐mediated L‐DOPA synthesis, and whole‐cell glycolysis under continuous flow conditions, is demonstrated. It is shown that the protocell‐nested enzymes and bacterial cells exhibit enhanced activities and stability under deleterious operating conditions compared with their non‐encapsulated counterparts. These results provide a step toward the engineering of continuous flow reactors based on cell‐like microscale agents and offer opportunities in the development of green and sustainable industrial bioprocessing.
