  • Patent number: 8198055
    Abstract: Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of CO2 and H2 with a surface of a membrane under anaerobic conditions and transferring these components in contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals. The gas fed on the membrane's gas contact side transports through the membrane to form a biofilm of anaerobic microoganisms that converted the syngas to desired liquid products. A liquid impermeable layer of the membrane assists in establishing direct gas phase contact syngas components with the microorganisms. The system can sustain production with a variety of microorganisms and membrane configurations.

    Abstract: A portable, self-contained incubation apparatus has a cell container in which a cell culture can grow. The cell container resides on a base along with other components that maintain the environmental conditions inside of the container within a desired range. The self-contained incubation apparatus is portable allowing the conditions within the cell container to be precisely controlled even as it is being moved from one location to another. Further, at least one transparent surface of the cell container enables observation of the cell culture. Thus, the culture can be observed while the environmental conditions within the container are being controlled by components of the incubation apparatus. Since the cells can be observed without breaking the air-tight seal of the container, observation of the cells can be performed as often as is desired without introducing contaminants to the culture or otherwise significantly affecting the growth environment within the container.

  • Patent number: 7851200
    Abstract: A bioreactor and a method for growing engineered tissue provide facing surfaces in a vessel for containing cell-culture media. The facing surfaces are equidistant and define a gap therebetween while providing substrates for cell tissue growth. By maintaining conditions within the vessel conducive to cell tissue growth and moving the surfaces relative to one another within such cell culture media, tissue growing thereupon is subjected to physiological flow and shear stress, preferably through the use of oscillating motion, and engineered tissue is produced.

  • Patent number: 7820434
    Abstract: A novel apparatus and device is described for reconstituting a bone sample with a biological fluid, such as concentrated plasma or saline solutions, for example, prior to surgical implantation into a patient. In particular, the invention comprises, in certain aspects, a container in which a bone sample may be reconstituted with the desired fluid by applying a vacuum within the container, thereby driving the fluid into the bone for complete, or near complete, permeation of the fluid into the interstices of the bone sample prior to surgical implantation.

  • Patent number: 7803608
    Abstract: An integrated filtration and detection device for collecting and detecting the growth of microorganisms in a specimen includes a container defining a chamber therein. The container has an inlet and an outlet in fluid communication with the chamber. A filter is mounted in the chamber between the inlet and the outlet. A sensor is mounted in the chamber. The sensor is operative to exhibit a change in a measurable property thereof upon exposure to changes in the chamber due to microbial growth.

  • Publication number: 20100227389
    Abstract: A biological reactor for growing a biological mass has a tank with an interior for growing the biological mass, a plate movable in a substantially vertical direction and an interior of the tank, and a valve means provided with the plate and configured so that in a lower position of the plate the valve means are open, so that during displacement of the plate upwardly and downwardly, a solution in the interior of the tank is thoroughly fixed, while an upper position of the plate, the valve means are closed and the plate during movement downwardly provides a collection of a concentrated solution to be removed from the tank.

  • Patent number: 7790443
    Abstract: A bioreactor with substance injection capability. In one embodiment, the bioreactor includes a first substrate having a first surface, an opposite second surface and edges. The bioreactor further includes a second substrate having a first surface and an opposite second surface, defining a cavity with a bottom surface, where the bottom surface is located therebetween the first surface and the second surface. The first surface of the first substrate is received by the second surface of the second substrate to cover the cavity so as to form a chamber for receiving cells and a liquid medium. A port is formed in the second substrate between the bottom surface and the first surface of the second substrate. As formed, the port is in fluid communication with the chamber to allow a stream of substance to be introduced into the chamber. The stream of substance is controlled so as to provide a gradient, or a concentration gradient of the substance, to the chamber.

  • Publication number: 20100136686
    Abstract: A disclosure is made of various apparatus and methods for culturing and preserving cells and tissue in ways that minimize contamination potential, direct cells to reside in desired areas, allow uniform cell distribution during seeding, provide optimal growth conditions by controlling the amount of medium residing in proximity of cells, allow desired compounds and molecules to reside in proximity of the cells, allow co-culture, provide for efficient scale up, allow a desired shape of tissue to be created while retaining a closed system, and allow cryopreservation and reconstitution of cell and tissue while retaining a closed system. The apparatus and methods can be combined to prevent the need to remove the tissue from the enclosure at any point during the sterilization, seeding, culturing, cryopreservation, shipping, or restoration process. Also disclosed is an apparatus and method of pipette interface with a container in a manner that blocks contaminants from entering the container.

  • Patent number: 7708806
    Abstract: A method and apparatus for extracting CO2 from air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted CO2 to controlled environments. The present invention contemplates the extraction of CO2 from air using conventional extraction methods or by using one of the extraction methods disclosed; e.g., humidity swing or electro dialysis. The present invention also provides delivery of the CO2 to greenhouses where increased levels of CO2 will improve conditions for growth. Alternatively, the CO2 is fed to an algae culture.
