  • Publication number: 20190390135
    Abstract: Disclosed herein are processes for obtaining a microbial oil comprising one or more polyunsaturated fatty acids (PUFAs) from one or more microbial cells by lysing the cells to form a lysed cell composition, treating the lysed cell composition to form an oil-containing emulsion and then recovering the oil from the oil-containing emulsion. Further disclosed herein is microbial oil comprising one or more PUFAs that is recovered from microbial cells by at least one process described herein.

  • Publication number: 20190010419
    Abstract: Methods and systems used to extract lipids suitable in production of biofuels from a fermentation broth may include using heat to pre-treat the fermentation broth in order to more easily extract a product from oleaginous microorganisms in the broth. Additionally or alternatively, a combination of enzymes including amylase, 1-4 mannosidase, and 1-3 mannosidase may be used to break down cell walls of the oleaginous microorganisms. Residual broth water may be recycled and used as imbibition water for washing a process feedstock to extract sugar.

  • Patent number: 10039820
    Abstract: A West Nile virus vaccine for human use is described that preferably contains a recombinantly produced form of truncated West Nile virus envelope glycoprotein and aluminum adjuvant. The vaccine is acceptable for use in the general population, including immunosuppressed, immunocompromised, and immunosenescent individuals. The vaccine is safe and effective for use in all healthy and at-risk populations. A pharmaceutically acceptable vehicle may also be included in the vaccine.

  • Patent number: 8980590
    Abstract: Methods of separating renewable materials, such as lipids, from microorganisms, such as oleaginous yeasts, may include conditioning cell walls of the microorganisms to form, open or enlarge pores, and removing at least a portion of the renewable material through the pores. These methods may result in delipidated microorganisms with cell walls that are substantially intact and with mesopores. These delipidated microorganisms may be used to produce biofuels.

  • Patent number: 7618671
    Abstract: The present invention provides a process using zeolites for recovering isoflavones and removing undesired oligosaccharides from aqueous mixtures, such as soy whey and other plant processing waste products. The aqueous mixture is treated with a large pore hydrophobic zeolite, such as zeolite Beta, to remove isoflavones, followed by treatment with an ultrastabilized, hydrophobic zeolite Y, such as CBV-901 or HiSiv™ 4000, to remove the undesired oligosaccharides raffinose and stachyose. The recovered isoflavones and digestible sugars, glucose, sucrose, and fructose, are useful in food products.

  • Patent number: 7618672
    Abstract: The present invention relates to a process for selectively removing undesired oligosaccharides from aqueous mixtures such as plant processing waste products, including soy whey and other vegetable wheys, using an ultrastabilized large pore, hydrophobic zeolite Y. The resulting solution, which contains isoflavones and digestible sugars such as glucose, fructose and sucrose, can serve as the basis for a nutritious new product.

  • Publication number: 20050202139
    Abstract: The present invention provides a process using a zeolite or molecular sieve for recovering isoflavones from aqueous mixtures, such as soy whey and other biological waste products. A zeolite, such as a large pore, hydrophobic zeolite, has a significantly higher affinity for isoflavones than conventional polymeric adsorbents, and has essentially no affinity for the undesired oligosaccharides raffinose and stachyose.
