Abstract
Disclosed herein are compositions produced from microorganisms that are capable of producing high levels of docosapentaenoic acid (DPA(n-3)), and methods for producing the compositions. The invention is further directed to microbial strains and derivatives therefrom, biomasses, and microbial oils.
Claims44
A composition comprising a first microbial oil, wherein the first microbial oil comprises long chain polyunsaturated fatty acids (LC-PUFAs), and wherein the LC-PUFAs comprise docosapentaenoic acid (DPA(n-3)) and docosahexaenoic acid (DHA) in a ratio of DPA(n-3):DHA greater than 0.2.
The composition of any preceding claim, wherein the LC-PUFAs in the first microbial oil comprise DPA(n-3) in an amount at least about 7% by weight of the total fatty acids.
The composition of any preceding claim, wherein the LC-PUFAs in the first microbial oil comprise DPA(n-3) in an amount between about 7% to about 12% by weight of the total fatty acids.
The composition of any preceding claim, wherein the LC-PUFAs in the first microbial oil comprise DPA(n-3) in an amount between about 8% to about 11% by weight of the total fatty acids.
The composition of any preceding claim, wherein the first microbial oil is mixed with a second oil, and wherein the second oil comprises a vegetable, plant, fish, microbial oil, or combination thereof.
The composition of any preceding claim wherein the first microbial oil is obtained from a microorganism selected from the group consisting of algae, bacteria, fungi and protists.
The composition of any preceding claim, wherein the composition is a food product, cosmetic or pharmaceutical composition.
A method of preparing a composition comprising combining nutritional components and LC-PUFAs, wherein the LC-PUFAs comprise DPA(n-3) and DHA, and wherein the ratio of DPA(n-3):DHA is from about 0.2:1 to about 1:1.
A method of preparing a composition, comprising combining nutritional components and an oil blend, wherein the oil blend comprises a first microbial oil having a DHA:DPA(n-3) ratio of 0.2-0.7:1, and a second oil comprising one or more of a vegetable oil, a plant oil, a fish oil, or a microbial oil having a DHA:DPA(n-3):EPA ratio of 0.2-0.7:1:0.2-0.7
A composition for consumption by a human, wherein the composition comprises long chain polyunsaturated fatty acids (LC-PUFAs) and wherein, when ready for consumption by the human, the LC-PUFAs comprise docosapentaenoic acid n-3 (DPA(n-3)) and docosahexaenoic acid (DHA) in a ratio of DPA(n-3):DHA greater than 0.2.
An isolated microbial strain deposited in the Culture Collection of Algae and Protozoa under accession number CCAP 3067/1, or a strain derived therefrom.
A method of preparing a composition comprising combining nutritional components and LC-PUFAs, wherein the LC-PUFAs comprise DPA(n-3) and DHA, and wherein the ratio of DPA(n-3):DHA is from about 0.2:1 to about 1:1.
A method of preparing a composition, comprising combining nutritional components and an oil blend, wherein the oil blend comprises a first oil comprising one or more of a plant, fish, or microbial oil, and a second oil, wherein the oil is a microbial oil having a DHA:DPA(n-3):EPA ratio of 0.01-0.7:1:0.01-0.7
