The present invention relates to novel mutant thioesterase enzymes and naturally-occurring equivalents thereof, compositions made from such enzymes and uses of thioesterase enzymes. In particular, the present invention provides mutant thioesterase enzymes that have altered properties, for example, altered substrate specificity, altered activity, altered selectivity, and/or altered proportional yields in the product mixtures. The present invention also provides polynucleotides encoding such mutant thioesterase enzymes, and vectors and host cells comprising such polynucleotides. The invention further provides for novel uses of thioesterases in the production of various fatty acid derivatives, which are useful as, or as components of, industrial chemicals and fuels.

The present invention relates to a sinter powder composed of polyamide which also comprises metal salts of weak acids, in particular metal carbonates, and fatty acid derivatives, in particular fatty acid esters or fatty acid amides, to a process for laser sintering, and also to moldings produced from this sinter powder. The moldings formed using the powder of the invention have marked advantages in appearance and in surface finish when compared with conventional products, especially when recyclability in the selective laser sintering (SLS) process is taken into account. Moldings produced from recycled sinter powder of the invention moreover also have markedly improved mechanical properties when compared with moldings based on recycled conventional nylon-12 powders, in particular in terms of modulus of elasticity and tensile strain at break. These moldings also have a density approaching that of injection moldings.

A mixture having good thermal stability, flow and moldability and suitable as a golf ball-forming material is obtained when a base resin comprising a (metal ion-neutralized) olefin-unsaturated carboxylic acid-unsaturated carboxylate ternary random copolymer and optionally a (metal ion-neutralized) olefin-unsaturated carboxylic acid binary random copolymer is blended with specific proportions of a fatty acid and/or fatty acid derivative and a basic inorganic metal compound capable of neutralizing acidic groups left unneutralized in the base resin and fatty acid. Using the same material, high-rebound golf balls can be effectively manufactured.

A method that produces coupled radical products from biomass. The method involves obtaining a lipid or carboxylic acid material from the biomass. This material may be a carboxylic acid, an ester of a carboxylic acid, a triglyceride of a carboxylic acid, or a metal salt of a carboxylic acid, or any other fatty acid derivative. This lipid material or carboxylic acid material is converted into an alkali metal salt. The alkali metal salt is then used in an anolyte as part of an electrolytic cell. The electrolytic cell may include an alkali ion conducting membrane (such as a NaSICON membrane). When the cell is operated, the alkali metal salt of the carboxylic acid decarboxylates and forms radicals. Such radicals are then bonded to other radicals, thereby producing a coupled radical product such as a hydrocarbon. The produced hydrocarbon may be, for example, saturated, unsaturated, branched, or unbranched, depending upon the starting material.

Methods and compositions for producing fatty acid derivatives, for example, fatty esters, are described.

The invention discloses a strain producing long chain dibasic acid, which is candida tropicalis CAT N145 with a collection number of CCTCC M 2011192.

The present invention relates to materials exhibiting the property of rubbery elasticity, consisting of molecules with a mass of between 9 and 9000 g/mol, all or some of the molecules having at least three groups (also referred to as “associative groups”) capable of associating via non-covalent interactions.

Although consisting of small non-polymerized molecules that are not chemically crosslinked, this material exhibits properties of rubbery elasticity. According to an embodiment of the invention, this material exhibits rubbery elasticity at ambient temperature. Above a certain temperature, the material flows like a simple liquid. The material is thermoreversible, i.e. after cooling, the material again exhibits the property of rubbery elasticity. This material is self-repairing and potentially recyclable, which is never the case with a chemically crosslinked elastomer.
