Abstract
A bioreactor is disclosed in which cells are confined to a compartment formed by porous hydrophyllic sheet membranes through which a nutrient solution diffuses in and exocellular products and metabolic waste diffuse out. Adjacent gas compartments allow the flow of free oxygen into the cell compartment. Each cell compartment is configured to place cells within about 100-200 micrometers of the oxygen transport membrane.
