Patent number: 6344344Abstract: Uridine-5′-monophosphate is produced by cultivating in a nutrient medium an uridine-5′-monophosphate producing mutant of coryneform bacterium and which is characterized by at least a resistance to growth inhibition by pyrimidine analogue or a deficiency in uridine degrading activity or combination of said property by protoplast fusion. This method has the advantage of decreased production of uracil. Thus, uridine-5′-monophosphate can be produced in much greater yields, compared with known methods.Type: GrantFiled: October 25, 2000Date of Patent: February 5, 2002Assignee: Ajinomoto Co., Inc.Inventors: Lyudmila Anatolievna Kazarinova, Vitaliy Arkadievich Livshits, Ekaterina Sergeevna Preobrazhenskaya, Irina Mikhailovna Starovoytova

Patent number: 6344345Abstract: Disclosed is a method for producing double-stranded DNA comprising treating double-stranded DNA having a homopolymer part or parts at one or both ends with a restriction enzyme to partly or fully eliminate at least one of the homopolymer part or parts. The restriction enzyme is capable of cleaving double-stranded DNA at a cleavage site separate from a recognition site therefor. Disclosed is a method for determining a nucleotide sequence of double-stranded DNA utilizing one or both strands of the double-stranded DNA as a template, wherein the double-stranded DNA used as the template is double-stranded DNA prepared by the above method of the present invention.Type: GrantFiled: November 5, 1999Date of Patent: February 5, 2002Assignee: RikenInventor: Yoshihide Hayashizaki

Patent number: 6344348Abstract: The invention provides a process for the production of aspartic acid poly-condensate from a carbohydrate comprising the steps of: fermenting a carbohydrate-containing medium by means of a fumaric acid-producing microorganism, whereby a fumarate-containing fermentation liquor is formed; forming a purified ammonium fumarate solution from the fumarate-containing fermentation liquor; enzymatically converting the purified ammonium fumarate into purified ammonium aspartate; heating an aqueous solution of an aspartate salt derived from the purified ammonium aspartate whereby water is removed, an aspartic acid condensate is formed and a second product is formed, which second product is basic and contains the cation of the aspartate salt; and removing and using the basic second product as a reagent in another step of the process.Type: GrantFiled: November 22, 1999Date of Patent: February 5, 2002Assignee: Amylum Belgium N.V.Inventors: Aharon Eyal, Robert J. Jansen, Asher Vitner, Pierre Cami, Emmanuel Mailly, Thomas Chattaway, Bruno Jarry, Joelle More
