  • Patent number: 8071326
    Abstract: A rapid method for the quantitation of various live cell types is described. This new cell fluorescence method correlates with other methods of enumerating cells such as the standard plate count, the methylene blue method and the slide viability technique. The method is particularly useful in several applications such as: a) quantitating bacteria in milk, yogurt, cheese, meat and other foods, b) quantitating yeast cells in brewing, fermentation and bread making, c) quantitating mammalian cells in research, food and clinical settings. The method is especially useful when both total and viable cell counts are required such as in the brewing industry. The method can also be employed to determine the metabolic activity of cells in a sample. The apparatus, device, and/or system used for cell quantitation is also disclosed.

  • Publication number: 20110281254
    Abstract: This disclosure discloses a process and an anaerobic digestion system for crop stalk/straw. The process in one example comprises (A) Feeding, (B) Heating and Digestion at the set temperature, (C) Discharging of Biogas, Sludge and Effluen{grave over ( )}t. The system in one example comprises (I) High Solid Content Digester (II) Hydro-Circulation Digester and (III) Stalk/Straw Feeder. Steps (A), (B) and (C) are accomplished in the devices (I) and (II). The step (A) is accomplished through the stalk/straw feeder (III), a special feeding mechanism, by which the crushed or smashed stalk/straw is pushed into the bottom of digester vessel. After being fermented or digested in the device (I), feedstock that is the mixture of biomass and water flows freely into the device (II) through the feedstock discharge outlet. The stalk feeder (III) is comprised of a hopper (7), a support (14), a control system and a hydraulic system.

  • Publication number: 20110281336
    Abstract: The present invention relates to methods for sustaining a microbial culture during periods of limited substrate supply. In accordance with the methods of the invention a microbial culture comprising carboxydotrophic bacteria can be sustained during periods of limited substrate supply by maintaining the temperature of the microbial culture at a temperature below an optimum operating temperature.

  • Publication number: 20110281297
    Abstract: A device is operable to measure the size of tissue particles. The device includes a reservoir for receiving tissue particles and an ultrasonic transducer. The ultrasonic transducer is operable to emit ultrasonic energy toward tissue particles in the reservoir. Control circuitry is operable to process ultrasonic energy received from the ultrasonic transducer to determine the size of tissue particles in the reservoir. If the tissue particles are larger than a predetermined size range, the particles may be minced to reduce their size. If the tissue particles are smaller than a predetermined size range, the particles may be disposed of. It the tissue particles have a size within a predetermined range, they may be processed further, such as by stimulating the tissue particles and dewatering the tissue particles. The tissue particles may then be incorporated in a medical fluid and be therapeutically administered to a patient.

  • Patent number: 8057655
    Abstract: Sub-micron objects are manipulated. According to an example embodiment of the present invention, Brownian motion effects are mitigated to facilitate the analysis and/or manipulation of sub-micron objects. In some applications, an electric field is applied to facilitate the manipulation of sub-micron objects in solution, facilitating the analysis of the manipulated objects. In other applications, fluid flow is used to effect the manipulation of sub-micron objects in solution.
