Abstract:
The invention relates to animal food additives containing a vitamin B6, a method for producing said additives, animal food compounds containing the inventive additive and a method for introducing said additives into the animal food compounds.
Abstract:
The invention concerns a method for producing optically active alcohols of formula (I) by means of enzymatic reduction of the corresponding ketones, in particular, the production of (1S)-3-methylamino-1-(2-thienyl)-propane-1-ol and (1S)-3-chlorine-1-(2-thienyl)-propane-1-ol.
Abstract:
The invention relates to a method for producing carotenoids or their precursors using genetically modified organisms of the Blakeslea genus. Said method comprises the following steps (i) transformation of at least one of the cells, (ii) optional homokaryotic conversion of the cells obtained in step (i) to produce cells, in which one or more genetic characteristics of the nucleii are all modified in an identical manner and said modification manifests itself in the cells, (iii) selection and reproduction of the genetically modified cell or cells, (iv) cultivation of the genetically modified cells, (v) preparation of the carotenoids produced by the genetically modified cells or the carotenoid precursor produced by said genetically modified cells. The invention also relates to carotenoids or their precursors produced according to said method and to the use thereof.
Abstract:
A new feed additive (I), containing vitamin B6 (VB6), is derived from the fermentation broth of a VB6-producing microorganism and comprises a mixture of VB6 with at least one non-volatile component of the broth. An Independent claim is included for the preparation of (I).
Abstract:
The present invention relates to a method for purifying (1S)-3-METHYLAMINO-1-(2-THIENYL)-1-PROPANOL by distilling a reaction mixture which comprises between 25 and 99% by weight of (IS)-3-METHYLAMINO-1-(2-THIENYL)-1-PROPANOL.

Abstract:
Production of vitamin B6 (I) involves: (a) preparing a fermentation broth containing (I) by culturing a suitable microorganism in a nutrient medium; (b) removing the cells to give a solution containing (I); (c) purifying (I) in the solution by (i) ion exchange chromatography (optionally at elevated temperature) or (ii) aqueous-aqueous two-phase extraction; or (d) optionally purifying the obtained (I)-containing fractions by crystallization. An independent claim is included for the isolation of (I) from an aqueous medium, by stages (c) and (d) as above.
Abstract:
Preparing carotenoids (I) or their precursors (Ia) using genetically modified organisms of the genus Blakeslea, is new. Preparing carotenoids (I) or their precursors (Ia) using genetically modified organisms of the genus Blakesleacomprises: (1) transforming at least one cell; (2) optionally homokaryotizing the cells so that cells are produced in which the nuclei are all simultaneously altered in one or more genetic characteristics and these alterations are expressed; (3) selection, multiplication and culture of the modified cell(s); and (4) recovery of (I) and (Ia) from the cells. Independent claims are also included for: (1) producing at least one high-purity (I) and a nutrient, consisting of (I)-producing organisms and at least one (I), by culturing a (I)-producing Blakeslea; and (2) human and animal foods or food supplements produced by the new method.
