Disclosed is a transformation method whereby an ability to produce a useful substance of a stramenopile can be improved. The method for transforming a stramenopile comprises transferring a foreign gene into the stramenopile which is a microorganism belonging to the class Labyrinthula, more specifically, to a genus Labyrinthula, Altornia, Aplanochytrium, Schizochytrium, Aurantiochytrium, Thraustochytrium, Ulkenia, etc. Said foreign gene, which is a gene relating to tolerance against an antibiotic, a colorimetric protein and/or a fatty acid desaturase (5 desaturase gene, 12 desaturase gene and/or 3 desaturase gene), is transferred by using the electroporation or gene-gun technique.

[Problem] Provision of a method for fractionating lipids using liquefied dimethyl ether as a solvent. [Means for Solving] To provide a method for fractionating a lipid using liquefied dimethyl ether as a solvent. [Solution] A method for fractionating a lipid, which comprises subjecting a microbial biomass to extraction using liquefied dimethyl ether as a solvent and then fractionating the lipid utilizing separation selectivity for the lipid. A method for producing a lipid, which comprises subjecting a microbial biomass to extraction using liquefied dimethyl ether as a solvent, then fractionating a portion of the lipid utilizing separation selectivity for the lipid to modify the fatty acid composition of the remainder of the lipid which remains in the microbial biomass, and then extracting the lipid having a modified fatty acid composition.

A crude microbial oil comprises arachidonic acid (20:4 6) as highly unsaturated constituent fatty acid, at not less than 30% by weight arachidonic acid content based on total fatty acid in the crude oil. The ester-type sterol content of the fat or oil is not more than 0.8% by weight. Also disclosed is a process for producing such crude oil by culturing a microorganism in a medium containing nitrogen source at a concentration of 2 to 15% in a culture tank equipped with an agitation impeller satisfying the requirement that the ratio of the diameter of the agitation impeller (d) to the inner diameter of the culture tank (D) is d/D = 0.30 to 0.6.

Provided is a method for producing a processed food which is produced by continuously heating/molding a fluid raw material containing a protein, a lipid, and water. A method for heating a material to be heated continuously by an internal heating system while moving the material in a tube comprising: (a) arranging the tube vertically or substantially vertically (a tilt of not greater than 15) and heating/molding a mixture while feeding the mixture upward from a bottom in the tube and/or (b) heating/molding the mixture while rotating the tube around a rotation axis, the rotation axis being a center line in a length direction of the tube. The internal heating system is preferably microwave heating, Joule heating, or high-frequency heating. The method for producing a processed protein food employs the heating/molding method for production of a processed protein food wherein a material to be heated, which is a fluid mixture containing a protein, a lipid, and water, is molded by thermally coagulating the mixture continuously by an internal heating system while moving the mixture in a tube.
