  • Biological oils and production and uses Thereof
    Publication number: 20090064567
    Abstract: The present invention provides biological oils and methods and uses thereof. The biological oils are preferably produced by heterotrophic fermentation of one or more microorganisms using cellulose-containing feedstock as a main source of carbon. The present invention also provides methods of producing lipid-based biofuels and food, nutritional, and pharmaceutical products using the biological oils.

  • Production of DHA in microalgae in low pH medium
    Patent number: 7252979
    Abstract: Methods for production of highly unsaturated fatty acids by marine microorganisms, including the heterotrophic marine dinoflagellate Crypthecodinium, using low levels of chloride ion are disclosed. Specifically, methods of increasing production of highly unsaturated fatty acids by marine microorganisms while growing in low chloride media by manipulating sodium ion and potassium ion levels. The invention also relates to methods of production of highly unsaturated fatty acids by marine organisms at low pH levels, and includes methods for generation of low pH tolerant strains.
