Abstract:
PROBLEM TO BE SOLVED: To provide genetically engineered organisms for producing PHA (polyhydroxyalkanoate) copolymers containing 2-hydroxyacid monomers, a method for producing the same and a method of application. SOLUTION: The copolymers containing the 2-hydroxyacid monomers are synthesized by a biosynthesis by the action of PHA polymerase in a living cell. By changing the genetic background of the cells, specific metabolic pathways enabling the control of glycolic acid comonomer level in the PHA polymers can be regulated. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for separating polyhydroxyalkanoate ("PHA") from a plant such as transgenic oil crop plant. SOLUTION: In order to isolate PHA, in an embodiment, a biomass derived from an oil crop plant is pre-processed, for example, by grinding, crushing or rolling. Then, the oil is extracted from the biomass with the first solvent in which the oil is soluble and the PHA is not highly soluble and the oil is removed. The biomass then can be extracted with the second solvent in which the PHA is soluble, to separate the PHA from the biomass. Alternatively, the PHA-containing biomass is treated with a chemical or biochemical agent, such as an enzyme, to chemically transform the PHA into a PHA derivative. The PHA derivative then is separated from the mixture using, for example, a physical separation process such as distillation, extraction or chromatography. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a recombinant process to transfer a further gene into a transgenic PHB producer to produce a new strain synthesizing a monomer of a substitute PHA (poly [(R)-3-hydroxyalkanoate]) (e.g. 4HB (copolymer poly (3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV)) and provide a technique and procedure to stably produce a transgenic organism synthesizing a PHA containing 4-hydroxybutyric acid as the sole constituent or a comonomer. SOLUTION: A gene encoding a heterologous enzyme selected from polyhydroxyalkanoate synthase and 4HB-CoA transferase is stably transferred into a genom to obtain a recombinant host.

Abstract:
PROBLEM TO BE SOLVED: To provide a recombinant process capable of incorporating a further gene into a PHB(polyhydroxybutyric acid) producer in order to create a new strain synthesizing a monomer of an alternative polyhydroxyalkanoate(PHA) (e.g. 4-hydroxybutyric acid/4HB), and to provide a method for stably creating an organism synthesizing a 4HB-containing PHA as either of sole construct or comonomer. SOLUTION: The method uses such a recombinant host that its genome is stably incorporated with a gene encoding a heterologous enzyme selected from the group consisting of a PHA synthase and a 4HB-CoA transferase.

Abstract:
PROBLEM TO BE SOLVED: To provide methods for separating polyhydroxyalkanoates ("PHA") from plants, such as transgenic oil crop plants. SOLUTION: To isolate the PHA, in one embodiment, a biomass derived from an oil crop plant is pre-processed, for example by grinding, crushing or rolling. Then the oil is extracted from the biomass with a first solvent (in which solvent the oil is soluble and the PHA are not highly soluble) to remove the oil. Then the biomass can be extracted with a second solvent (in which solvent the PHA is soluble) to separate the PHA from the biomass. Alternatively, the PHA-containing biomass is treated with a chemical or biochemical agent to chemically transform the PHA into a PHA derivative. Then the PHA derivative is separated from the mixture by using, for example, a physical separation process. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide the technology and process for stably making a transgenic organism synthesizing PHA including 4-hydroxy-butyric acid as only one component or as co-monomer by using the recombination process in which another gene is introduced into the transgenic PHP producer, in order to create a new strain synthesizing the substitute PHA monomer (for example, 4-HB). SOLUTION: A recombinant host that stably incorporates the gene encoding different kinds of enzyme selected from polyhydroxyalkanoate synthase and 4HB-CoA transferase into the genome.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for separating polyhydroxyalkanoates ("PHAs") from plants such as a transgenic oil crop plant. SOLUTION: In an embodiment of the method, to isolate the PHAs, a biomass derived from an oil crop plant is preprocessed by, for example, grinding, crushing or rolling. Oil is then extracted from the biomass by using a first solvent (in which the oil is soluble and the PHAs are not highly soluble) to remove the oil. Then, the biomass can be extracted by using a second solvent (in which the PHAs are soluble) to separate the PHAs from the biomass. Alternatively, the PHA-containing biomass is treated with a chemical or biochemical agent to chemically transform the PHA into a PHA derivative. The PHA derivative is then separated from the mixture by using a physical separation process. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
Oligomers and polymer compositions are provided which comprise GHB and produce GHB after administration in vivo . Devices for the storage and delivery of these polymers and oligomers are also provided. These oligomers and polymer compositions are useful in a variety of applications. The compositions can be used therapeutically, for example, in the treatment of patients with narcolepsy, chronic schizophrenia, catatonic schizophrenia, atypical psychoses, chronic brain syndrome, neurosis, alcoholism, drug addiction and withdrawal, Parkinson's disease and other neuropharmacological illnesses, hypertension, ischemia, circulatory collapse, radiation exposure, cancer, and myocardial infarction. Other uses for the compositions include anesthesia induction, sedation, growth hormone production, heightened sexual desire, anorectic effects, euphoria, smooth muscle relaxation, muscle mass production, and sleep, including rapid eye movement sleep. In a still further embodiment, the oligomers and polymers may be used to produce absence seizures.
Abstract:
Polyhydroxyalkanoates (PHAs) from which pyrogen has been removed are provided for use in numerous biomedical applications. PHAs which have been chemically modified to enhance physical and/or chemical properties, for targeting or to modify biodegradability or clearance by the reticuloendothelia system (RES), are described. Methods for depyrogenating PHA polymers prepared by bacterial fermentation processes are also provided, wherein pyrogens are removed from the polymers without adversely impacting the polymers' inherent chemical structures and physical properties. PHAs with advantageous processing characteristics, including low melting points and/or solubility in non-toxic solvents, are also described. PHAs are provided which are suitable for use in in vivo applications such as in tissue coatings, stents, sutures, tubing, bone and other prostheses, bone or tissue cements, tissue regeneration devices, wound dressings, drug delivery, and for diagnostic and prophylactic uses. Properties which are selected for include degradability, elasticity, inclusion of functional groups or derivatized groups, which can in turn be used to attach targeting agents, and bioadhesion.
