摘要:
The present invention relates to a process of preparing a rubber-like material containing a protein immobilized therein, as well as a corresponding rubber-like material, the process comprising the steps of (a) mixing a protein, a branched polymer such as trimethylolpropane ethoxylate and a linear polymer such as poly(ethylene oxide) in an aqueous solution to form a gel, and (b) drying the gel to obtain a rubber-like material containing the protein immobilized therein, wherein the branched polymer comprises at least three polymeric branches bound to a central branching unit. The rubber-like material allows the immobilization and stabilization of a wide range of different proteins, including luminescent proteins as well as enzymes, and can particularly advantageously be used as down-converting material for light-emitting diodes (LEDs), for diagnostic applications, and in bioreactors.
摘要:
Recombinant DNA techniques are used to produce oleaginous recombinant cells that produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Genes manipulated include those encoding stearoyl-ACP desturase, delta 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl-ACP synthase, and lysophosphatidic acid acyltransferase. The oil produced can have enhanced oxidative or thermal stability, can be useful as a frying oil, shortening, roll-in shortening, tempering fat, cocoa butter replacement, as a lubricant, or as a feedstock for various chemical processes. The fatty acid profile can be enriched in midchain profiles or the oil can be enriched in triglycerides of the saturated-unsaturated-saturated type.

摘要:
One aspect provides an ultrapure, hypoallergenic sacrosidase. Another aspect provides a solution of sacrosidase in about 1:1 glycerol/water having an enzymatic activity of at least about 7500 IU/mL and a residual papain concentration that does not include an allergic reaction in a human patient when given a dose of about 2.0 mL/day.
摘要:
The invention provides methods of cultivating oil-bearing microbes using xylose alone or in combination with other depolymerized cellulosic material. Also provided are microorganisms comprising an exogenous gene encoding a polysaccharide degrading enzyme, such as a cellulase, a hemicellulase, a pectinase, or a driselase. Some methods of microbial fermentation are provided that comprise the use of xylose and depolymerized cellulosic materials for the production of oil-bearing microorgansims.
摘要:
The invention provides methods of modifying the lipids produced by microbial organisms through genetic engineering. The invention also provides genetically engineered microbes and methods of fermenting microbes for oil production. Also provided are oils, fuels, oleochemicals, chemical precursors, and other compounds manufactured by such modified microorganisms. Exemplary oil-bearing organisms include organisms containing one or more exogenous genes encoding a fatty acyl-ACP thioesterase, fatty acyl-CoA/aldehyde reductase, fatty acyl-CoA reductase, fatty aldehyde reductase, fatty aldehyde decarbonylase, and/or an acyl carrier protein.
摘要:
The present invention relates to recombinant cells and microorganisms of the phylum Labyrinthulomycota and their use in heterologous protein production. Novel promoter, terminator, and signal sequences for efficient production and, optionally, secretion of polypeptides from recombinant host cells and microorganisms are also encompassed by the present invention.

摘要:
The present invention relates to genetically engineered organisms, especially microorganisms such as bacteria and yeasts, for the production of added value bio-products such as specialty saccharide, activated saccharide, nucleoside, glycoside, glycolipid or glycoprotein. More specifically, the present invention relates to host cells that are metabolically engineered so that they can produce said valuable specialty products in large quantities and at a high rate by bypassing classical technical problems that occur in biocatalytical or fermentative production processes.
摘要:
Methods and compositions for the production of food compositions, oils, fuels, oleochemicals, and other compounds in recombinant microorganisms are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Microalgal cells containing exogenous genes encoding, for example, a lipase, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a keto acyl-ACP synthase enzyme, a fatty acyl-ACP thioesterase, a fatty acyl-CoA/aldehyde reductase, a fatty acyl-CoA reductase, a fatty aldehyde reductase, a fatty aldehyde decarbonylase, and/or an acyl carrier protein are useful in manufacturing food compositions, and transportation fuels such as renewable diesel, biodiesel, and renewable jet fuel, as well as oleochemicals such as functional fluids, surfactants, soaps and lubricants.
