Patent number: 7045340Abstract: A bacterial composition, a process and a facility for the pre-treatment of effluent rich in organic fats of animal or vegetable origin. The bacterial composition principally is the bacterial strain Klebsiella oxytoca. The process consists of supplying a homogenisation and/or processing vessel (1) with effluent to be pre-treated, as it is produced, activating a recirculation circuit (2) between the vessel and a biological reactor (3) to obtain a fat dilution rate situated between 0.400 h?1 and 1.500 h?1 for an initial fat concentration of 1 g/l, degrading the fats in the biological reactor (3) using the bacterial composition and discharging the pre-treated effluent to a final treatment unit such as a purification plant.Type: GrantFiled: July 27, 2001Date of Patent: May 16, 2006Assignee: Aqua Terra Environnement Holding S.A.Inventors: Jairo Falla, Daniel Morabito, Gunter Graf, Thierry Sensenbrenner, Astride Ritter

Patent number: 6225438Abstract: This invention relates to polymer production and in particular to a novel copolymer and a process for microbiologically producing the same. More specifically this invention provides for a poly-3-hydroxyalkanoate (PHA) that includes medium length 3-hydroxyacyl monomers and a process comprising culturing a microorganism with a medium chain fatty carbon source and a fatty acid oxidation inhibitor. This invention allows the use of microorganisms which normally incorporate only short chain fatty acids to produce PHAs containing short and medium chain 3-hydroxyacyl monomers. The purpose of this invention is to produce a more versatile PHA polymer which includes C6, C7 and/or C8 3-hydroxyacyl monomers.Type: GrantFiled: January 31, 2000Date of Patent: May 1, 2001Assignee: The Procter & Gamble CompanyInventor: Phillip Richard Green

Patent number: 5559029Abstract: New protozoan derived microbial consortia and method for their isolation are provided. Consortia and bacteria isolated therefrom are useful for treating wastes such as trichloroethylene and trinitrotoluene. Consortia, bacteria isolated therefrom, and dispersants isolated therefrom are useful for dispersing hydrocarbons such as oil, creosote, wax, and grease.Type: GrantFiled: May 19, 1995Date of Patent: September 24, 1996Assignee: Martin Marietta Energy Systems, Inc.Inventor: Richard L. Tyndall

Patent number: 5360737Abstract: A microorganism belonging to the genus Enterobacter and having a plant growth acceleratory activity, particularly Enterobacter cloacae, and a method for cultivating crops using the microorganism or polysaccharides produced therefrom are disclosed.Type: GrantFiled: September 2, 1993Date of Patent: November 1, 1994Assignee: Meiji Seika Kaisha, Ltd.Inventors: Takafumi Ishii, Takashi Adachi, Toshio Yasumura, Shinji Miyadoh, Hidemasa Hidaka
-
Patent number: 5354671Abstract: A novel enzyme composition capable of lysing or digesting cells or cellular debris of polysaccharide-producing bacteria in the presence of the exopolysaccharides without any significant degradation of the exopolysaccharides. Methods for preparing the enzyme composition, using the composition to clarify mixtures of polysaccharides and cellular debris, and pure cultures for making the enzyme are disclosed.Type: GrantFiled: June 26, 1992Date of Patent: October 11, 1994Assignees: Shin-Etsu Chemical Co., Ltd., Shin-Etsu Bio, Inc.Inventor: Thomas J. Pollock

Patent number: 5292860Abstract: The present invention is directed to a copolymer containing a 3-hydroxybutyrate (3HB) unit and a 3-hydroxyhexanoate (3HHx) unit, a three-component copolymer containing at least a 3-hydroxybutyrate (3HB) unit and a 3-hydroxyhexanoate (3HHx) unit, and a four-component copolymer containing at least a 3-hydroxybutyrate (3HB) unit and a 3-hydroxyhexanoate (3HHx) unit. The use of a microorganism of the genus Aeromonas according to the present invention makes it possible to produce a wide variety of plastic materials ranging from rigid plastics to elastic plastics by selecting copolymer components and adjusting their composition.Type: GrantFiled: September 16, 1992Date of Patent: March 8, 1994Assignee: Kanegafuchi Kagaku Kogyo Kabushiki KaishaInventors: Takeshi Shiotani, Genta Kobayashi

Patent number: 4517008Abstract: A novel agriculturally useful composition that includes a seed treated with selected infectivity-cured Hr plasmid-bearing microorganism. Also provided are methods of enhancing root elongation, shoot elongation or root development of selected seeds. These methods include treating a selected seed with the infectivity-cured Hr plasmid-bearing microorganism. In addition, there is provided a method of inducing germination of grass seed that involves treating a grass seed such as Kentucky bluegrass seed with a selected infectivity-cured Hr plasmid-bearing microorganism. Furthermore, there is provided a method of promoting plant growth at a lower soil temperature than is common at the time of planting a seed of the plant. Additionally, there is disclosed an inoculant for increasing nodulation, root mass and shoot mass in a leguminous plant. The inoculant contains a Rhizobium microorganism and a selected infectivity-cured Hr plasmid-bearing microorganism.Type: GrantFiled: June 16, 1982Date of Patent: May 14, 1985Assignee: Research and Development Institute, Inc. at Montana State UniversityInventors: Gary A. Strobel, Andrea H. Gavlak, Jesse M. Jaynes
