Abstract: The present invention relates generally to a method for increasing the yield of plasmid DNA production. The method includes the steps of selecting a highly productive clonal subtype of a strain of E. coli, including but not limited to the DH5 strain, harboring a DNA plasmid and cultivating said clonal subtype with fed-batch fermentation in a chemically-defined medium. The plasmid DNA production process described herein can generate record quantities of plasmid DNA when said highly productive clonal subtypes are cultivated on an industrial scale. The disclosed method can be used for the production of pharmaceutical grade DNA for use in polynucleotide vaccination and gene therapy treatment regimens.

Abstract: A control system is applied to a vehicle cruise device which is installed in a vehicle driven by an internal-combustion engine that has a speed control mechanism to control the vehicle speed. The control system includes a traveling signal input end, a command input end, a memory, a processor, and a control signal output end. The traveling signal input end is used for inputting the vehicle traveling signal into the control system. The command input end is connected to the command module for receiving the control command from the driver. The memory is used for storing the setting parameters of the control system. The processor is used for generating a control signal according to the control command, traveling signal, and setting parameters. The control signal output end is used for outputting the control signal generated by the processor, thereby controlling the drive mechanism so as to control the vehicle speed.
