  • Enhanced production of lipids containing polyenoic fatty acid by very hugh density cultures of eukaryotic microbes in fermentors
    Patent number: 7732170
    Abstract: The present invention provides a process for growing eukaryotic microorganisms which are capable of producing lipids, in particular lipids containing polyenoic fatty acids. The present invention also provides a process for producing eukaryotic microbial lipids.
    Type: Grant
    Filed: April 5, 2006
    Date of Patent: June 8, 2010
    Assignee: Martek Biosciences Corporation
    Inventors: Richard B. Bailey, Don DiMasi, Jon M. Hansen, Peter J. Mirrasoul, Craig M. Ruecker, George T. Veeder, III, Tatsuo Kaneko, William R. Barclay
  • Solventless extraction process
    Patent number: 7662598
    Abstract: The present invention provides a method for extracting lipids from microorganisms without using organic solvent as an extraction solvent. In particular, the present invention provides a method for extracting lipids from microorganisms by lysing cells and removing water soluble compound and/or materials by washing the lysed cell mixtures with aqueous washing solutions until a substantially non-emulsified lipid is obtained.
    Type: Grant
