| 20090087886 | METHOD FOR PRODUCING AN L-AMINO ACID USING A BACTERIUM OF THE ENTEROBACTERIACEAE FAMILY WITH ATTENUATED EXPRESSION OF THE sfmACDFH-fimZ CLUSTER OR THE fimZ GENE - The present invention provides a method for producing an L-amino acid using a bacterium of the Enterobacteriaceae family, particularly a bacterium belonging to genus | 04-02-2009 |
| 20090137010 | METHOD FOR PRODUCING AMINO ACIDS USING BACTERIUM OF THE ENTEROBACTERIACEAE FAMILY - A method for producing an L-amino acid is described, for example, L-phenylalanine and L-histidine, by fermentation using a bacterium of the Enterobacteriaceae family, wherein the bacterium has been modified by attaching a DNA fragment able to be transcribed encoding the peptide represented in SEQ ID NO: 2, or a variant thereof, particularly a portion of the ssrA gene, to the 3′-end of gene encoding for the bacterial enzyme, which influences on the L-amino acid biosynthesis, such as chorismate mutase/prephenate dehydrogenase or phosphoglucose isomerase. | 05-28-2009 |
| 20100099153 | Method for producing L-amino acids using bacteria belonging to the genus escherichia - A method for producing lower alkyl ester of α-L-aspartyl-L-phenylalanine by cultivating a recombinant | 04-22-2010 |
| 20100184162 | METHOD FOR PRODUCTION OF AN L-AMINO ACID - A method is provided for producing an L-amino acid by culturing a microorganism belonging to the Enterobacteriaceae family and having the ability to produce an L-amino acid, in a medium to produce and accumulate the L-amino acid in the medium. The microorganism has been modified by introduction of a DNA fragment which includes a pho regulon promoter and a structural gene encoding an L-amino acid biosynthetic enzyme, which is ligated downstream of the promoter so that the gene is expressed by the promoter, and so that the activity of the L-amino acid biosynthetic enzyme is increased by the expression of the gene by the promoter. In this way, the L-amino acid that is produced in the medium can be collected. Furthermore, the phosphorus concentration in the medium is such that the expression of the gene by the promoter is induced. | 07-22-2010 |
| 20110143403 | METHOD FOR PRODUCING L-AMINO ACIDS USING BACTERIA OF THE ENTEROBACTERIACEAE FAMILY - There is disclosed a method for producing L-amino acid, for example L-threonine, L-lysine, L-histidine, L-phenylalanine, L-arginine or L-glutamic acid, using a bacterium of the Enterobacteriaceae family, wherein the bacterium has been modified to enhance an activity of D-xylose permease. | 06-16-2011 |

| 20090152458 | METHOD AND APPARATUS FOR ION FRAGMENTATION IN MASS SPECTROMETRY - A method for fragmentation of analyte ions for mass spectroscopy and a system for mass spectroscopy. The method produces gas-phase analyte ions, produces gas-phase radical species separately from the analyte ions, and mixes the gas-phase analyte ions and the radical species at substantially atmospheric pressure conditions to produce fragment ions prior to introduction into a mass spectrometer. The system includes a gas-phase analyte ion source, a gas-phase radical species source separate from the gas-phase analyte ion source, a mixing region where the gas-phase analyte ions and the radical species are mixed at substantially atmospheric pressure to produce fragment ions of the analyte ions, a mass spectrometer having an entrance where at least a portion of the fragment ions are introduced into a vacuum of the mass spectrometer, and a detector in the mass spectrometer which determines a mass to charge ratio analysis of the fragment ions. | 06-18-2009 |
| 20100288920 | METHOD AND APPARATUS FOR ION FRAGMENTATION IN MASS SPECTROMETRY - A method for fragmentation of analyte ions for mass spectroscopy and a system for mass spectroscopy. The method produces gas-phase analyte ions, produces gas-phase odd-electron containing species separately from the analyte ions, and mixes the gas-phase analyte ions and the odd-electron containing species at substantially atmospheric pressure conditions to produce fragment ions prior to introduction into a mass spectrometer. The system includes a gas-phase analyte ion source, a gas-phase odd-electron containing species source separate from the gas-phase analyte ion source, a mixing region where the gas-phase analyte ions and the odd-electron containing species are mixed at substantially atmospheric pressure to produce fragment ions of the analyte ions, a mass spectrometer having an entrance where at least a portion of the fragment ions are introduced into a vacuum of the mass spectrometer, and a detector in the mass spectrometer which determines a mass to charge ratio analysis of the fragment ions. | 11-18-2010 |
