Abstract: The present invention provides compositions for a crude algal oil and methods of making thereof. The compositions can be used to produce a highly pure omega-3 eicosapentaenoic acid (EPA) formulation.

Abstract: Provided herein are exemplary algal fatty acid compositions comprising by dry weight approximately 0.5% to approximately 99% C20:5 n3 Eicosapentaenoic acid (EPA) and approximately 0.5% to approximately 99% C16:1 n7 palmitoleic acid (POA). Further exemplary algal fatty acid compositions may comprise (in addition to the above) one or more of the following by dry weight: between approximately 0% and 99% arachidonic acid; between approximately 0% and 99% docosahexaenoic acid; and/or less than approximately 10% saturated fatty acids (including 0% saturated fatty acids or substantially saturated fatty acid free). Further exemplary saturated fatty acyl moiety-rich algal compositions may be in a form of an ethyl ester (EE), a mono, di- or triacylglycerol (MAG, DAG, TAG), a phospholipid (PL), a galactolipid (GL), free fatty Acid (FFA), or a sulfoquinovosyl diacylglycerol (SQDG).

Abstract: Various embodiments of the present invention include systems and methods for converting free fatty acids to ethyl esters. An exemplary method may comprise contacting the free fatty acid with a non-polar solvent. A mineral acid and an alcohol may then be added to form a two-phase mixture. An aqueous phase my subsequently be removed from the mixture. The processes and methods may be used in the manufacture of supplements, pharmaceuticals, cosmetic and beauty products, feedstocks, and the like.

Abstract: Provided herein are exemplary total algal oil compositions comprising by total weight between approximately 0% and 99% EPA, and one or more of the following: between approximately 0% and 99% POA, less than approximately 20% saturated fats (including 0% saturated fats or substantially saturated fat free), between approximately 0% and 99% ARA, and/or between approximately 0% and 99% DHA. According to further exemplary total algal oil compositions, the saturated fats may comprise PA. Also provided herein are exemplary total algal oil compositions comprising by total weight at least 20% EPA and one or more of the following: at least 17% POA, approximately 0% to 20% saturated fats, less than approximately 10% ARA, and/or substantially no DHA.

Abstract: Provided herein are exemplary algal omega 7 compositions, including algal fatty acid compositions comprising by dry weight from about approximately 0.5% to about approximately 99% C16:1 n7 palmitoleic acid (POA). Such algal compositions may also include (either individually or any combination of) by dry weight: from about approximately 0% to about approximately 20% saturated fatty acids; from about approximately 0% to about approximately 99% arachidonic acid; from about approximately 0% to about 99% docosahexaenoic acid; and/or from about approximately 0% to about approximately 99% eicosapentaenoic acid. Further exemplary algal fatty acid compositions may include by dry weight about approximately 90% POA, less than about approximately 20% saturated fatty acids, less than about approximately 10% ARA, substantially no DHA, and less than about approximately 10% EPA.
