  • Patent number: 11054362
    Abstract: A system and method adapted to have high sensitivity to the formation of biofilm by mixed community bacteria in fluids. The system enhances corrosion imbalance by differentiating conditions between metal sensor elements immersed in the liquid being monitored. The liquid may be diverted to and flowed through a sample chamber where adjacent sensor elements may reside in different flow velocity or temperature regions. The differentiated conditions allow for different film formation on one of the sensor elements relative to the other, and also more quickly than in the main system from which the sampled liquid has been diverted. The differentiated formation allows the use of measurement of polarization current between the metal sensors to produce data with superior resolution relative to prior methods. The speed of film formation promoted by the differentiated conditions allows for determination of risk of film formation in the main system prior to that film's formation in the main system.

In this manner, mechanisms of cell-cell interaction and other chemical signaling, detailed biochemical pathways, and the action of potential pharmaco-therapy agents can be better understood at a molecular level. In addition to basic science, the technical advantages of process monitoring and control can be applied to optimize culture products in bioreactors.

  • Patent number: 10704017
    Abstract: A cell culture carrier module and a cell culture system having the same are provided. A cell tank and a culture medium module respectively communicate with the carrier module. The carrier module includes a reactor, a first fixer, a second fixer and a plurality of cell culture carriers. The reactor has a chamber and at least one inlet/outlet. The inlet/outlet communicates with the chamber. The first fixer is fixed to the reactor and located in the chamber. The second fixer is disposed in the chamber and is movable relative to the first fixer. Two ends of each cell culture carrier are fixed to the first fixer and the second fixer, respectively. The cell culture carriers are in an untwisted state or a twisted state according to a variation in a distance between the first fixer and the second fixer due to a movement of the second fixer.
