Patent number: 7022509Abstract: A method for removing a gas from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the compound to be removed into the gas vesicles, and placing the gas vesicles such that the gas compound is removed from the site. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium—such as darkness, exponential growth stage, flocculation, or dissolved gas flotation—then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.Type: GrantFiled: May 10, 2002Date of Patent: April 4, 2006Assignee: The University of AkronInventors: Lu-Kwang Ju, Anand Sundararajan, Sunil Kashyap

Patent number: 6413763Abstract: A method for removing a gas compound from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the gas compound to be removed into the gas vesicles, and placing the gas vesicles contacted with a medium such that the gas compound is removed from the site to the medium. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium. Then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.Type: GrantFiled: January 21, 2000Date of Patent: July 2, 2002Assignee: The University of AkronInventors: Lu-Kwang Ju, Anand Sundararajan, Sunil Kashyap

Patent number: 6406690Abstract: A biologically pure strain of Bacillus firmus (CNCM I-1582) possessing nematicidal activity is provided. Also provided are compositions containing and methods for employing the Bacillus firmus strain and a biologically pure strain of Bacillus cereus (CNCM I-1562) possessing nematicidal activity. Nematicidally active mutants of these strains are also provided. Further disclosed are nematicidal compositions for use in plant protection based upon these bacterial strains or mutants thereof. Further disclosed are methods for controlling plant-pathogenetic nematodes which include use of these bacterial strains or mutants thereof. The strains find utility in controlling root-knot disease causing nematodes, for example those belonging to the species Meloidogyne.Type: GrantFiled: July 10, 1998Date of Patent: June 18, 2002Assignee: Minrav Industries Ltd.Inventors: Itzhak Peleg, Katherina Feldman

Patent number: 6395532Abstract: The present invention relates to modified enzymes with one or more amino acid residues from an enzyme being replaced by cysteine residues, where at least some of the cysteine residues are modified by replacing thiol hydrogen in the cysteine residue with a thiol side chain to form a modified enzyme, wherein the modified enzyme has high esterase and low amidase activity. Also, a method of producing the modified enzymes is provided. The present invention also relates to a method for using the modified enzymes in peptide synthesis.Type: GrantFiled: January 21, 1999Date of Patent: May 28, 2002Assignees: Genencor International, Inc.Inventor: J.

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
