The present invention relates to the Schizochytrium genus SR21 strain and a microorganism belonging to the same species as does said SR21 strain or having substantially the same fungological properties as does said SR21 strain, the said SR21 strain and microorganism having the ability to produce the (n-3) series of docosahexaenoic acid (DHA) and the (n-6) series of docosapentaenoic acid (DPA), and the invention also relates to a process for preparing the (n-3) series of DHA and the (n-6) series of DPA utilizing said microorganisms. The microorganisms according to the present invention are superior in their proliferation character and their propensity to produce fat, and have the ability to produce the (n-3) series of DHA and the (n-6) series of DPA very well. Accordingly, it is possible to effectively produce the (n-3) series of DHA and/or the (n-6) series of DPA, which are useful in the fields of foods and pharmaceuticals, using the microorganisms according to the present invention. In addition, the present invention provides a fat obtained by culturing the present microorganisms. Since the fat composition contains the (n-6) series of DPA in addition to the (n-3) series of DHA having various physiological activities, it is possible to stably and effectively supply the (n-6) series of DPA and/or the (n-3) series of DHA to subjects in need of these highly unsaturated fatty acids by adding the fat composition to various feedstuffs or foods.

Eicosapentaenoic acid (EPA) compositions and EPA-rich polar lipids for prophylactic or therapeutic applications are described. Production from certain cultured micro-organisms (like Nitzschia laevis) promotes synthesis of EPA, including polar lipids including EPA. The EPA-rich polar lipids themselves may be used as polar compounds. EPA can be selectively hydrolysed from particular positions in isolated polar lipids by lipase activity, then optionally further purified. The process bypasses reliance on diminishing fish stocks and on physico-chemical processes that may not adequately separate desirable n-3 HUFAs from unwanted products like DHA also found in fish oil and cultured organisms.

By this invention, modification of the fatty acid composition of a plant seed may be achieved as a result of the activity of a DNA sequence foreign to the plant species to be modified. In particular, it has been found that a plant oil having a modified fatty acid composition can be obtained upon the expression of genes derived from plants of different species than the host plant, upon the expression of genes derived from bacteria, and from the transcription of anti-sense sequences which are complementary to endogenous genes of the plant host cell. In a preferred embodiment, transcription of the fatty acid modifying foreign DNA sequence is restricted to the developing seed tissues.

The invention relates to edible nutritious oil which is characterized in that the contents of saturated fatty acid, oleic acid, linoleic acid and linolenic acid are respectively 8 to 16 percent, 42 to 56 percent, 13 to 23 percent and 13 to 30 percent of total fatty acid. With the proposal of eating less saturated fatty acid and linoleic acid and more oleic acid and linolenic acid from the international alimentology community, the edible oil is designed based on the particular reference that the ratio of the linoleic acid to the linolenic acid is close to 1 to 1 in the meal of human beings and people in Crete, Greece 100 years ago. The edible oil which has more balanced ratio between the fatty acid is quite suitable for human beings and has very important effects on reducing human beings fatness, hypertension, high blood fat, cardiovascular and cranial vascular diseases and cancers and reinforcing intelligence development. In addition, the edible oil has high quality and low price.

Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability. The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste water processing entirely. Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.

A process for the fractionation of valuable fractions from cereal brans (e.g. wheat, barley and oat brans, and rice polish) is described. In particular, this invention describes a two step process, in which the said bran is first subjected to a combination of enzymatic treatment and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main bran factions, i.e. insoluble phase (pericarp and aleurone layer), germ-rich fraction, residual endosperm fraction and soluble sugars. A second step consists of fractionating cereal brans substantially free of soluble compounds, hence insoluble phase from the above-mentioned first step, by enzymatic treatment with xylanases and/or beta-glucanase and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main fractions, i.e. insoluble phase (remaining cell wall components), protein-rich fraction, soluble hemicellulose and oligosaccharide, and therefore maximizes the extraction rate of valuable cell wall components and aleurone cells from previously cleaned bran.
