  • Patent number: 11104923
    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.
    Type: Grant

  • Publication number: 20210030023
    Abstract: The present invention relates to the use of alpha lipoic acid as feed additive for aquatic animals including fish and shrimp, especially for cold water fish as for example salmon, bream, bass and for warm water fish as for example carp, tilapia, catfish. More particular, this invention relates to the use of alpha lipoic acid for the improvement of the feed conversion ratio and/or daily weight gain in fish, for reducing mortality by regulating the micro flora of the gut and/or by protecting the animal against infections caused by pathogenic viruses.

  • Publication number: 20120323029
    Abstract: Methods, biological oils, biofuels, units, and/or organisms directed to use in compression engines. A method of producing biological oils includes producing an organism and having the organism consume a feedstock. The organism includes a lipid containing fatty acids. The organism meets or exceeds at least two metrics. The metrics include: A) a cell density of at least about 115 grams per liter; B) a fatty acid content of at least about 49 percent on a dry mass basis; C) a fatty acid productivity of at least about 15 grams per liter per day; D) a fatty acid yield of at least about 0.175 grams of fatty acids produced per grams of the feedstock consumed; E) a 24 hour peak fatty acid productivity of at least about 30 grams per liter per day; F) an extraction efficiency on a percent of total fatty acid content basis of at least about 50 percent; and/or G) yield of fatty acids on oxygen of more than about 0.4 as grams of fatty acids produced per gram of oxygen consumed basis.
