  • Patent number: 8765408
    Abstract: The present invention provides a bacterium having a genome that is genetically engineered to be smaller than the genome of its native parent strain. A bacterium with a smaller genome can produce a commercial product more efficiently. The present invention also provides methods for deleting genes and other DNA sequences from a bacterial genome. The methods provide precise deletions and seldom introduces mutations to the genomic DNA sequences around the deletion sites. Thus, the methods can be used to generate a series of deletions in a bacterium without increasing the possibility of undesired homologous recombination within the genome. In addition, some of the methods provided by the present invention can also be used for replacing a region of a bacterial genome with a desired DNA sequence.

  • Patent number: 7935251
    Abstract: A facility for treating solid and liquid waste includes a receiving station, a screening station, a preprocessing station, an alkali mixing station, a press station and a processing station. The screening station is connected to an inlet capable of receiving liquid and solid waste and includes a screen for capturing at least some of the solid waste. The preprocessing station is in fluid communication with the screening station, and includes a degrit chamber for settling out an additional amount of the solids. The alkali mixing station includes an alkali for mixing with the waste to stabilize the waste at a predetermined pH level. The press station receives the stabilized waste and includes a press for separating out an additional portion of the solids. The processing station includes at least one aerobic microorganism generating unit for converting nitrites into nitrogen gas and consuming carbon-based waste material.

  • Patent number: 5445952
    Abstract: The present invention relates to a method to enhance a cell's ability to produce biotin precursors and/or biotin by deregulating at least one enzyme of the fatty acid biosynthetic pathway in the cell, preferably an enzyme that carries out an early step in the pathway. Preferably, the biotin biosynthetic pathway is also deregulated. The invention includes biotin-producing cells in which at least one enzyme of the fatty acid biosynthetic pathway is deregulated, preferably by transforming the cells with nucleic acid sequences encoding at least one of those enzymes; methods to produce such cells; and use of such cells to produce biotin.

  • Patent number: 5054727
    Abstract: A shipping, storage and racking method and apparatus for packages designed to be hung on pegs on display racks includes a storage/transfer member dimensioned to pass through the openings by which the packages are hung. An opening is provided along the longitudinal axis of the storage/transfer member to permit the member to be slid over a display rack peg so that packages on the peg can be supported by the member and removed as a single unit by holding them on the member as it is slid off the peg. A reverse procedure is used to deposit packages carried on a storage/transfer member onto a peg. Packages are stored and transported by supporting a storage/transfer member loaded with packages within a container by special means which position and secure the member so that the packages are hung within the container without resting on the container bottom.

  • Patent number: 4891508
    Abstract: The precision infrared position detector apparatus uses an information display device that has a substantially cylindrical shaped screen to limit curvature of the screen to a single dimension. In addition, to compensate for this curvature, a flexible printed circuit board is used to align the row of infrared light sources and detectors along the same curvature as the screen of the information display device. A first flexible printed circuit board is equipped with a single row of infrared light sources while a second flexible printed circuit board is equipped with a signal row of corresponding infrared light detectors. A frame member is used to bend the flexible printed circuit board into a substantially cylindrical shape that matches the curvature of the screen of the information display device.
