Definitions
- the present invention relates to a method for extracting a fat-soluble component contained in a microbial cell, and more particularly, to a method capable of extracting and recovering a fat-soluble component in a microbial cell extremely efficiently and safely.
- microorganisms such as filamentous fungi, yeast, and algae have lipid-producing ability
- a method of extracting lipid from microorganisms having such lipid-producing ability has been used.
- lipid since lipid accumulates in the microbial cells, a method of extracting the lipid directly from the cells or mechanically or enzymatically lysing the cell wall is known.
- microbial cells capable of producing fats and oils are suspended in ethanol, crushed, and then ethanol is separated by filtration and centrifugation. Then, an extraction solvent is added thereto, suspended, and crushed and extracted.
- a method has been proposed (Japanese Patent Application Laid-Open Nos. 61-170,977, 61-227,790, 62-414, and 62-197). — 1 7 9 5 9 Publication etc.).
- the invention described in Japanese Patent Application Laid-Open No. 61-170,977 particularly relates to a multi-stage extraction method.
- alcohol solvents and hydrocarbon solvents are used.
- a different solvent must be used, and furthermore, in each step, it is necessary to perform an operation of separating the bacterial cells and the organic solvent each time, so that the operation is complicated.
- the extraction rate is high and the fat-soluble components in the microbial cells can be safely extracted and recovered, but the extraction takes a long time because the crushed fine powder clogs the extraction column. There was a problem of doing it. Disclosure of the invention
- the present inventors have conducted intensive studies to solve such conventional problems, and as a result, have found that dried microbial cells containing fat-soluble components are extruded, especially biaxial extruded. After crushing and forming in a single step, it was found that by extracting with a solvent, it was possible to extract and recover the fat-soluble components in the microbial cells extremely efficiently and in a short time. The invention has been completed.
- the present invention relates to a method of extracting a fat-soluble component contained in a microbial cell from the microbial cell containing the fat-soluble component, wherein the dried product of the microbial cell is extracted with an extruder, especially a biaxial elastomer. It is intended to provide a method for extracting microbial cells / fat-soluble components, which comprises crushing and shaping with a cruster, and then extracting a fat-soluble component in the microbial cells using an organic solvent.
- FIG. 1 is an explanatory diagram showing columns used in Examples.
- the fat-soluble component extracted by the method of the present invention is a substance that is hardly soluble in water, easily soluble in an organic solvent, and present in a living body, and includes, for example, (1) neutral lipids (such as triglycerides), wax, Simple lipids such as glycerides, fat-soluble pigments, esters of sterol-vitamin, (2) complex lipids such as phospholipids and glycolipids, (3) precursors and metabolites of the above two Derived lipids composed of fatty acids, higher alcohols, sterols, or carotenoids squalene, which are considered to be hydrocarbons, and fat-soluble vitamins.
- neutral lipids such as triglycerides
- Simple lipids such as glycerides
- fat-soluble pigments such as glycerides
- esters of sterol-vitamin esters of sterol-vitamin
- complex lipids such as phospholipids and glycolipids
- the microbial cell containing a fat-soluble component used in the method of the present invention is obtained by culturing a microorganism having a fat-soluble component-producing ability by an ordinary method.
- examples of the microorganism having the ability to produce a fat-soluble component include various microorganisms such as filamentous fungi, algae, yeast, and bacteria.
- microorganisms having the ability to produce ⁇ -linolenic acid-containing fats and oils include microorganisms belonging to the genus MortiereUa, microorganisms belonging to the genus Mucor, microorganisms belonging to the genus Rhizopus, and the like.
- microorganisms capable of producing dihomo- ⁇ -linolenic acid-containing oils and fats and arachidonic acid-containing oils include microorganisms belonging to the genus MortiereUa and microorganisms belonging to the genus Conidioholus.
- Microorganisms having the ability to produce linoleic acid-containing fats and oils include microorganisms belonging to the genus Yarrowia.
