摘要： The invention relates to the isolation of polyunsaturated fatty acids (PUFAs) from a lipids containing biomass. The main characteristics of the method are that a suspension of cells containing PUFAs is obtained and the cells are optionally lysed. The suspension is concentrated and then incubated for at least an hour at a controlled temperature while adding a specific range of base equivalents to biomass and maintaining a moderate pH. The isolation of lipid may be performed in the absence of organic solvents and without the addition of salt.

摘要： Disclosed herein are processes for obtaining a microbial oil comprising one or more polyunsaturated fatty acids (PU-FAs) from one or more microbial cells by lysing the cells to form a lysed cell composition and then recovering the oil from the lysed cell composition. Further disclosed herein is microbial oil comprising one or more PUFAs that is recovered from microbial cells by at least one process described herein.

摘要： Processes are disclosed for obtaining a lipid from a cell by lysing the cell to form a lysed cell composition, adding an acid to lower the pH of the lysed cell composition, and demulsify the lysed cell composition, and obtaining the lipid from the demulsified lysed cell composition. Also disclosed are lipids prepared by the processes of the present invention wherein the lipids have a particular anisidine value, peroxide value, and/or phosphorus content.
