Patent number: 8329456Abstract: A stable system for producing liquid products such as ethanol, butanol and other chemicals from syngas components contacts CO or a mixture of CO2 and H2 with a highly porous side of an asymmetric membrane under anaerobic conditions and transferring these components into contact with microorganisms contained within bio-pores of the membrane. The membrane side of the membrane utilizes a dense layer to control hydration of the bio-pores with a liquid phase. The gas feed directly contacts the microorganisms in the bio-pores and maximizes their utilization of the syngas. Metabolic products produced by the microorganisms leave the membrane through the side opposite the entering syngas. This system and method establishes a unitary direction across the membrane for the supply of the primary feed source to the microorganisms and the withdrawal of metabolically produced products. The feed and product flow improves productivity and performance of the microorganism and the membrane.Type: GrantFiled: February 22, 2008Date of Patent: December 11, 2012Assignee: Coskata, Inc.Inventors: Shih-Perng Tsai, Rathin Datta, Rahul Basu, Seong-Hoon Yoon

Patent number: 8021871Abstract: Systems and methods for automatically controlling conditions of a process are disclosed. In one example, a controller is programmed with a sequence of steps and parameters required to carry out a bioreactor process. A sensor system interacts with the bioreactor to receive information related to a condition of the bioreactor and/or receive a sample from the bioreactor, which it analyzes. The sensor system sends data signals related to the information and/or the sample to a controller, which determines a control signal based on the received information. The controller sends the control signal to the sensor system which, based on the control signal, performs an action that affects a condition of the bioreactor or affects the sensor system itself.Type: GrantFiled: December 21, 2009Date of Patent: September 20, 2011Assignee: Broadley-James CorporationInventor: Larry Eugene West

Patent number: 8017383Abstract: A solution temperature control device in a biological cell observing chamber (30) used for the detection of chemotaxis and chemotactic cell separator, comprising a first temperature controller (62) and a second temperature controller (63). The first temperature controller (62) measures the temperature of a solution filled in a pair of wells and a flow passage in the chamber and controls the temperature to a specified temperature, and the second temperature controller (63) measures the temperature of a heating part (64) which heats the chamber (30) from the outside to indirectly heat the solution filled in the pair of wells and the flow passage and controls the temperature to a specified preheat temperature. Since the state and quantity of cells moving from one well to the other through the flow passage while holding the temperature of the solution at a specified temperature can be accurately observed and measured, accuracy for controlling the temperature of the solution can be remarkably increased.Type: GrantFiled: September 13, 2004Date of Patent: September 13, 2011Assignee: Hirata CorporationInventors: Kouichi Noguchi, Kazuyuki Matsumura, Takesi Mitsunaga, Shiro Kanegasaki
