  • Patent number: 10179332
    Abstract: A device for collecting cellular material from a fluid sample comprises first and second chambers that are releasably connected and which define a fluid flow path from the first chamber to the second chamber. A porous membrane is between the chambers when they are connected to each other, in the fluid flow path. An absorbent body is positioned in close proximity to the downstream surface of the porous membrane, and a resilient member is arranged to urge the absorbent body towards the porous membrane. In use, a sample introduced into the first chamber contacts the upstream surface of the porous membrane and fluid is drawn through the porous membrane and is absorbed by the absorbent body. Cellular material is retained upon the upstream surface of the porous membrane. After separation of the chambers, the porous membrane can be removed from the device for analysis of the deposited cellular material.

  • Patent number: 10017789
    Abstract: According to an embodiment, there is provided herein a system and method wherein knowledge of the syngas fermentation is combined with standard instrumentation to provide a stable control of gas supply to automatically poise the fermentation to provide both high conversion of CO and H2, and high selectivity for production of ethanol. The control is based on an automatic feedback loop that corrects for operational imbalance and maintains a stable continuous fermentation required for commercial operation. In a further embodiment, feed of syngas to ethanol fermentation can be optimally controlled using the pH of the broth as the input variable for flow control of the gas. This concept will automatically maintain the correct supply of syngas to the fermentation, and provide stable operation at optimal rates.

    Abstract: A biogas system operates according to the principle of dry fermentation with multiple biogas fermenters that are run in batch mode. One of the biogas fermenters has just been loaded with fresh biomass and the other biogas fermenters are in the state of producing biogas with a higher concentration of methane. The biogas fermenter just loaded with fresh biomass is closed and connected to the other biogas fermenters that are already producing biogas. In addition, there is a return of the biogas mixture from the freshly loaded biogas fermenter to at least one of the other biogas fermenters producing biogas. After expiration of a defined time duration, the return of the biogas mixture from the freshly loaded biogas fermenter is stopped. The defined time duration is determined based on the concentration of methane in the mixture of biogas generated in all of the biogas fermenters.

  • Patent number: 8597941
    Abstract: A bioreactor for sampling the headspace above cells includes a glass reactor vessel having an interior space and a plurality of valves operatively coupled to the interior space of the glass reactor vessel. The bioreactor includes a sample holder configured to reside in the interior space. The interior space includes a charge of air with a known composition of volatile organic gases and, in some instances, doped with carbon dioxide. The sample holder may hold cells, bacteria, or viruses. The headspace may be sampled after incubation to determine the VOC content or content of specific VOC constituents. Examples include acetaldehyde and hexanaldehyde.

  • Publication number: 20130189767
    Abstract: A bioreactor with an upward flowing impeller system for controlling a mammalian cell culture process is provided. The disclosed system enables control of the cell culture process by controlling the level of dissolved carbon dioxide in the cell culture media and prevent increases in the osmolality level is achieved by enhanced stripping of carbon dioxide via surface gas exchange with little or no damage to the mammalian cells. The use of an upward flow impeller combined with vertical baffles converts the swirling motions of the cell culture media into a largely vertical flow and promotes the removal of dissolved carbon dioxide via surface gas exchange with a sweep gas flowing over the top surface of the cell culture media within the bioreactor vessel.

  • Publication number: 20130183705
    Abstract: Systems and methods for converting algae to liquid methane are disclosed. The system in accordance with a particular embodiment includes an algae cultivator, an anaerobic digester operatively coupled to the algae cultivator to receive algae and produce biogas, and a biogas converter coupled to the anaerobic digester to receive the biogas and produce liquefied methane and thermal energy, at least a portion of the thermal energy resulting from a methane liquefaction process. The system can further include a thermal path between the biogas converter and at least one of the algae cultivator and the anaerobic digester. The system can still further include a controller coupled to the biogas converter and at least one of the algae cultivator and the anaerobic digester. The controller can be programmed with instructions that, when executed (e.g., based on measured variables of the system), direct the portion of thermal energy between the biogas converter and the algae cultivator and/or anaerobic digester.

    Abstract: Processes and apparatus are disclosed for the low energy, anaerobic bioconversion of hydrogen and carbon monoxide in a gaseous substrate stream to oxygenated organic compounds such as ethanol by contact with microorganisms in a deep, stirred tank fermentation system with high conversion efficiency of both hydrogen and carbon monoxide. Gas feed to the reactor is injected using a motive liquid to form a stable dispersion of microbubbles thereby reducing energy costs, and a portion of the off-gases from the reactor are recycled to (i) achieve a conversion of the total moles of carbon monoxide and hydrogen in the gas substrate to oxygenated organic compound of at least about 80 percent and (ii) attenuate the risk of carbon monoxide inhibition of the microorganism used for the bioconversion.
