Abstract:
A method for determining three-dimensional structural information of a protein involves producing the protein in a form substantially labeled with C or N or both or substantially labeled with N and C and partially labeled with H and subjecting the protein to nuclear magnetic resonance spectroscopic analysis. The isotopically labeled protein is produced by a method which involves producing a substantially labeled microbial protein hydrolysate, subjecting the protein hydrolysate to cation exchange chromatography to produce a partially purified labeled amino acid mixture, subjecting the partially purified labeled amino acid mixture to anion exchange chromatography to produce a purified labeled amino acid mixture and supplementing the purified labeled amino acid mixture with isotopically labeled cysteine and optionally with isotopically labeled glutamine and asparagine.
Abstract:
According to one embodiment, a food product comprises a non-fat base, one or more polyunsaturated fatty acids, and one or more stabilizing ingredients. The stabilizing ingredients are selected to reduce the rate at which the polyunsaturated fatty acids oxidize in the non-fat base. At least one of the one or more stabilizing ingredients comprises a protein, a lipid, or a protein-and-lipid combination.
Abstract:
The disclosure relates to methods of treating and preventing neurological disorder such as cognitive impairment (MCI), age-associated memory impairment (AAMI) or Alzheimer's disease comprising the administering to a human subject who is identified as being negative for the ApoE4 allele an effective amount of a composition comprising docosahexaenoic acid (DHA) to treat the age-related cognitive disorder, wherein the composition has a DHA to eicosapentaenoic acid (EPA) ratio higher than 4:1 wt/wt or has no EPA.
Abstract:
The present invention is directed to methods of improving cognitive function in subjects having age related cognitive decline or mild cognitive impairment and to methods of decreasing heart rate in a subject by administering dosage forms comprising docosahexaenoic acid (DHA) substantially free of eicosapentaenoic acid (EPA).
Abstract:
The present invention is directed to methods of reducing plasma triglyceride level in subjects by administering docosahexaenoic acid (DHA). The method can comprise administering daily to the subject a dosage form comprising docosahexaenoic acid ester substantially free of eicosapentaenoic acid (EPA), wherein the DHA is derived from an algal source. In some embodiments, the method comprises administering daily to the subject a dosage form comprising DHA ester substantially free of EPA, wherein the DHA ester is about 60 % to about 99.5 % (w/w) of the total fatty acid content of the dosage form. In some embodiments, the method comprises administering daily to the subject a dosage form comprising about 200 mg to about 4 g of DHA ester substantially free of EPA. In some embodiments, the foregoing methods also result in a lowering of the amount of total cholesterol in the subject.
Abstract:
Microwaveable popcorn compositions, products and methods of making the same are disclosed. The composition includes unpopped popcorn kernels, an oil comprising at least one omega-3 LC PUFA, and an oil that is solid at about 20°C. The an oil comprising at least one omega-3 LC PUFA can include a microbial oil prepared by extraction with isopropanol and water in the absence of winterization.
Abstract:
The present invention includes a solid fat composition that includes an oil having saturated fat and a microbial oil having a long chain polyunsaturated fatty acid and an emulsifier. In particular, the solid fat composition can have high levels of long chain polyunsaturated fatty acid and low amounts of emulsifiers. In preferred embodiments, the polyunsaturated oil is an unwinterized microbial oil. The invention also relates to methods for making such compositions and food, nutritional, and pharmaceutical products comprising said compositions. The present invention also includes a microbial oil product prepared by extracting an oil-containing fraction comprising at least one LC-PUFA from a microbial biomass, and treating the fraction by a process of vacuum evaporation, wherein the oil product has not been subject to one or more of a solvent winterization step, a caustic refining process, a chill filtration process, or a bleaching process.
Abstract:
Described herein is a novel three domain gene from Schizochytrium , denoted carotene synthase, that encodes a protein with three different enzymatic activities; phytoene dehydrogenase (PD), phytoene synthase (PS), and lycopene cyclase (LC). Also described is the isolated gene encoding the carotene synthase, homologues thereof, the enzyme encoded by such gene, biologically active portions and homologues thereof, recombinant nucleic acid molecules, microorganisms and plants that have been genetically modified to increase or decrease the action of such gene, and methods of producing carotenoids and derivatives thereof or methods of producing microorganisms and lipid products lacking pigmentation using the knowledge of the carotene synthase described herein.
Abstract:
Genetic fusions for use in genetic engineering of eukaryotic algae employ a promoter from a light harvesting protein fused to a protein of interest. The fusions can be introduced and selected using an antibiotic resistance determinant. One gene useful for such selection is the sh ble gene encoding a bleomycin binding protein.
