The present invention relates to a method for the stereo selective production of a trans-diol or a cis-diol or a hydroxyketone comprising the step(s) (i) conversion of a trans-diol or a cis-diol to a hydroxyketone and/or (ii) conversion of a hydroxyketoneto a cis-diol or a trans-diol, catalyzed by an enzyme, which is encoded by a nucleic acid sequence of SEQ ID NO: or wherein the enzyme comprises an amino acid sequence of SEQ ID NO: 2. The present invention also relates to the use of an enzyme encoded by a nucleic acid sequence of SEQ ID NO: 1 or wherein the enzyme comprises an amino acid sequence of SEQ ID NO: 2 for the conversion of a trans-diol to a cis-diol or for the conversion of a trans-diol or a cis-diol to a hydroxy ketone and/or the conversion of a hydroxyketone to a trans-diol or a cis-diol.

Biotechnological production of diols

A process for increasing the concentration of PUFA triglycerides present in natural PUFA oils, in which a natural PUFA oil having a triglyceride content of more than 85% by weight, based on the total weight of the mixture, and having a total PUFA content of more than 39% by weight of total fatty acids is dissolved in an organic solvent or an organic solvent mixture, the mixture is allowed to stand at a temperature of from &#x2212;35&#xb0; C. to &#x2212;100&#xb0; C. for a period of more than five minutes, the mixture is separated into a supernatant comprising PUFA-triglyceride mixture and a sediment phase, the separation preferably taking place by filtration or centrifugation, and the solvent or solvent mixture, after the removal of the sediment phase, is separated from the supernatant. PUFA-triglyceride mixtures having a PUFA content of more than 55% by weight of total fatty acids of a main PUFA, or at least two PUFAs selected from stearidonic acid, eicosapentaenoic acid, docosapentaenoic acid, docosahexaenoic acid, gamma-linolenic acid and arachidonic acid, and also use thereof in pharmaceutical, cosmetics and food preparations.

Mixtures of triglycerides of natural polyunsaturated fatty acids with high polyunsaturated fatty acid content, method for producing same and use thereof

The invention relates to a method for the fermentative production of lipids/fatty acids having high concentrations of omega-6 fatty acids (PUFA, polyunsaturated fatty acids), especially &#x3b3;-linolenic acids (GLA) in ciliates. Said lipids/fatty acids can be used in human/animal food, and in the pharmaceutical field.

Method for producing &#x3b3;-linolenic acids from a ciliate culture by adding suitable precursor molecules to said culture medium

The present invention relates to a method for producing a saturated organic compound bearing at least one functional group from a mixture which comprises this saturated organic compound containing at least one functional group and also one or more other organic compounds, which comprises

Method for purifying compounds containing functional groups

The invention relates to a novel extraction method for obtaining at least one unsaturated, optionally derivatized compound, from mixtures of said compounds with other less saturated constituents, e.g. for obtaining polyunsaturated fatty acids or the derivatives thereof from mixtures with saturated and/or less unsaturated, optionally derivatized fatty acids, by means of selective complexation with a cation exchanger which is partially or fully charged with silver ions, and subsequent decomplexation.

Solid phase extraction method for obtaining high-purity unsaturated compounds or derivatives of said compounds

The intention relates to a method for the fermentative production of lipids/fatty acids having high concentrations of omega-6 fatty acids (PUFA, polyunsaturated fatty acids), especially &#x3b3;-linolenic acids (GLA) in ciliates. Said lipids/fatty acids can be used in human/animal food, and in the pharmaceutical field.

The invention relates to a method for obtaining fatty acid esters and fatty acids, preferably unsaturated fatty acid ethyl esters, from biological sources by continuous, combined in-situ extraction, reaction and chromatography. The invention is characterized in that simultaneously and in the same location, in the presence of a compressed gas and an 0.5-5 % stream of lower alcohols as modifiers and in the presence of an inert catalyst, the fatty acids are fully transesterified from their native fatty acid sources, which are selectively desorbed and eluated in the conditions specified above.
