  • GAS CONTROL IN AUTOMATED BIOREACTOR SYSTEM
    Publication number: 20150093741
    Abstract: A totipotent plant tissue multiplication system can include a plurality of bioreactors, an agitator to agitate culture in the bioreactors, and a gas source and control system. The gas source and control system can include a dissolved gas sensor in each of the bioreactors, gas sources, a manifold connected to each of the gas sources, and valves connected to the manifold. Each of the valves can be connected to one of the bioreactors. A controller can open the valves and control amounts of gas released from the gas sources into the manifold based on signals received from the dissolved gas sensors in each of the bioreactors.

  • CULTURE HARVESTING IN AUTOMATED BIOREACTOR SYSTEM
    Publication number: 20150093829
    Abstract: A system for harvesting totipotent plant tissue culture can include a sterile enclosure, a plurality of bioreactors in the sterile enclosure, at least one agitator in the sterile enclosure, and a culture harvest system. The at least one agitator can be configured to agitate culture within the plurality of bioreactors. The culture harvest system can include tubing configured to connect to a port of one of the plurality of bioreactors in the sterile enclosure, a culture harvest container, and a pump configured to pump culture from the one of the plurality of bioreactors into the culture harvest container via the tubing.
