  • Patent number: 10066217
    Abstract: Mutant thermophilic organisms that consume a variety of biomass derived substrates are disclosed herein. Strains of Thermoanaerobacterium saccharolyticum with acetate kinase and phosphotransacetylase expression eliminated are disclosed herein. Further, strain ALK1 has been engineered by site directed homologous recombination to knockout both acetic acid and lactic acid production. Continuous culture involving a substrate concentration challenge lead to evolution of ALK1, and formation of a more robust strain designated ALK2. The organisms may be utilized for example in thermophilic SSF and SSCF reactions performed at temperatures that are optimal for cellulase activity to produce near theoretical ethanol yields without expressing pyruvate decarboxylase.

  • Patent number: 8765428
    Abstract: The present invention is directed to a process for biologically converting carbohydrates from lignocellulosic biomass comprising the steps of: suspending lignocellulosic biomass in a flow-through reactor, passing a reaction solution into the reactor, wherein the solution is absorbed into the biomass substrate and at least a portion of the solution migrates through said biomass substrate to a liquid reservoir, recirculating the reaction solution in the liquid reservoir at least once to be absorbed into and migrate through the biomass substrate again. The biological converting of the may involve hydrolyzing cellulose, hemicellulose, or a combination thereof to form oligosaccharides, monomelic sugars, or a combination thereof; fermenting oligosaccharides, monomelic sugars, or a combination thereof to produce ethanol, or a combination thereof. The process can further comprise removing the reaction solution and processing the solution to separate the ethanol produced from non-fermented solids.

  • Publication number: 20040223417
    Abstract: A device for the storage and playback of audio signals originating from at least one portable medium includes a player for reading audio information from a portable medium having a plurality of audio tracks. The player transmits an audio output signal corresponding to a selected audio track. A storage device operatively connects to the player for receiving the output signal and storing the plurality of audio tracks. The device further includes a user interface control panel. A controller is adapted to receive user input from the control panel regarding desired playback of a selected track and records the playback information of the selected track in memory to prioritize the tracks relative to one another. The controller is further adapted to receive user input to control the player and the storage device to play at least portions of the stored plurality of audio tracks such that playing of the tracks is dependant on the playback information.

  • Patent number: 5761072
    Abstract: A microprocessor samples the net effective current from a battery several times a second. A fast average current I.sub.f is calculated using an IIR filter on the net average current. A slow average current I is calculated by integrating the net average current over time with respect to time. An Ampere Hour Capacity is calculated by the use of the Peukert equation, which is split into two terms. A first capacity term is calculated using the fast average current I.sub.f and a slow capacity term is calculated using the slow average current I. The slow capacity term is then multiplied by a weighting constant C.sub.2 and summed with the fast capacity term which is multiplied by (1-C.sub.2).
