The present invention is directed to a process for obtaining a lipid from a cell, the process involving lysing a cell to form a lysed cell composition; optionally adding a salt to the lysed cell composition; sequentially, in one or more cycles, raising the pH of the lysed cell composition to 10 or above for a period of time, followed by lowering the pH of the lysed cell composition to a pH of less than 6 for a period of time to demulsify the cell composition; and separating a lipid from the demulsified cell composition.

Methods to produce oils with modified profiles of fatty acid, carotenoids and/or terpenoids in microalgal mutants are provided. Microalgal mutants produce the oil containing fatty acids, carotenoids and/or terpenoids of a modified profile with a disruption or ablation of one or more alleles of an endogenous polynucleotide or comprising an exogeneous gene are also provided.

Provided are methods and/or systems having advantages of cost effective, time saving, and informative user-friendly characteristics to accomplish trait introgression. The methods provided comprise determining presence of omega-3 fatty acids (for example docosahexanoic acid or DHA; docosapentaenoic acid or DPA; Alpha linolenic acid or ALA; and eicosapentaenoic acid or EPA) using Fourier Transformed Infra Red (FTIR) spectrum. The use of FTIR enables analysis of the oil contained in the seeds using a multivariate-based Mid-FTIR model. The methods and/or systems provided advantages of non-destructive analysis to provide information to facilitate trait introgression and other breeding applications.

This invention relates to a method of using a two-step serial centrifugation process in extracting nutritive oil from a fermentation broth, this novel method prevents oil yield losses while preserving product quality.

This invention discloses a method for improving n-3 polyunsaturated fatty acid enrichment efficiency in glyceride, belonging to the field of deep processing of oil. The method of this invention includes providing oil, lipase and metal ionic liquid into a reactor. After a reaction time, a mixture is obtained and free fatty acid is removed from the mixture, and the product is the n-3 polyunsaturated fatty acid-rich glyceride. Compared with the traditional chemical method, the method of this invention is characterized by mild reaction conditions and producing lower level of by-products. Meanwhile, metal ions selected in the present invention are able to promote the hydrolysis of lipase, solving the problem of long reaction time in the conventional enzymatic method. Rapid hydrolysis is achieved by this method so as to realize enrichment of EPA and DHA in glyceride.

The disclosed subject matter relates generally to a method for modifying oil, and specifically to a process for increasing the concentration of polyunsaturated fatty acid in an oil composition. The process comprises a) hydrolysis of the glyceride by Thermomyces lanuginosus lipase, b) separation of the free saturated fatty acids from the glycerides and c) enzymatic esterification of the hydrolyzed glyceride by Candida antarctica lipase B with a polyunsaturated fatty acid.
