Cellulose sulphate encapsulation process. a Bacteria or yeast are mixed with Cellulose Sulphate (CS) and injected through a vibrating nozzle to form a stable jet of droplets which drop into the polymer pDADMAC. The droplets contain bacteria or yeast in the CS and harden as soon as they contact the pDADMAC to form capsules. After an appropriate hardening period, the capsules are washed. b The resulting capsules are porous and contain up to 5 million bacteria per capsule. c The capsules are regular and spherical in shape as evidenced by their appearance under the Scanning Electron Microscope, and when freeze fractured d reveal an outer related crust (consisting of CS and pDADMAC) and an inner space harboring the bacteria or yeast
