4665027 Immobilized cell reactorseparator with simultaneous product separation and methods for design and use thereof
PATENT ABSTRACTS generates the pulses that evolve into the highvoltage discharge output. The pulse control means is adapted to control the number of pulses within each cycle of the high-voltage discharge output. The burst control means, the cycle control means, the pulse generating means and the pulse control means produce a composite signal. The high-voltage discharge generating means is provided for transforming the low-voltage system voltage and the composite signal into the high-voltage discharge output.
4663293 DEVICE FOR TESTING AIR FOR MICROORGANISM CONTENT Hans D Hempel, Dieter Merz. Mainaschaff. Federal Republic Of Germany assigned to Biotest-Serum-lnstitut GmbH In a device for testing air for microorganism content with a rapidly rotating impeller inside a cylinder that has a backing sheet coated with culture medium against its inside surface, microorganisms that vary more extensively in size can be detected with almost equal effectiveness, the throughput of air can easily be determined, and the precipitation effect can be precisely tested because the backing sheet rotates along with the impeller, the blades of the propeller are at a low angle to the plane it rotates in, the air enters at a location that is separate from the location at which it leaves, through inlets from above and down and out through outlets, and the inner surface of the rotor below the impeller chamber is in the form of a channeling cylinder.
4665024 FLUORESCENT
GRAM STAIN
James Mansour assigned to Becton Dickinson and Company A method to determine the Gram sign of microorganisms includes staining the microorganisms with a plurality of fluorescent dyes, applying excitation energy to the stained microorganisms, and observing the color of the fluorescence emission of the stained microorganisms. Grampositive and Gram-negative microorganisms stain different colors, and assignment of the Gram sign may be made on the basis of the color of the stained microorganisms.

4665027 IMMOBILIZED CELL REACTORSEPARATOR WITH SIMULTANEOUS PRODUCT SEPARATION AND METHODS FOR DESIGN AND USE THEREOF M Clark Dale, Philip Wankat, Martin R Okos assigned to Bio-Process Innovation Inc A novel immobilized cell reactor design is described capable of separating an inhibitory metabolite from a fermentation broth as it is formed. This reactor has the dual advantages of (I) speeding product inhibited reactions and (2) giving a concentrated product free of substrate and cells. The immobilized cell reactor separator (ICRS) can consist of two columns; in the first or £1 enriching+2 + 0 column stripping gas and broth move co-currently after which the liquid phase moves to the top of the second + 1 stripping+2 + 0 column and moves counter currently to the stripping gas while the remaining substrate is converted to product. The use of this reactor in an ethanol from whey lactose fermentation system is also described. 4665033 PROCESS AND AN APPARATUS FOR CULTURING MICROORGANISMS IN A NUTRIENT SOLUTION Gerar Buchwalder, Delemont, Switzerland assigned to Zentrale Finanz- und KommerzAktiengesellschaft In a process for culturing microorganisms in a sealed vessel, the nutrient solution is circulated directionally and the microorganisms are kept in suspension in the moving directional flow. The oxygen-containing gas for aeration of the nutrient solution is run into the solution in such a way that it has a component of motion normal to the direction of flow of the nutrient solution.
