  • Method of fermentative alpha-ionone production
    Patent number: 11326173
    Abstract: The present invention concerns a method of producing and enantiomerically pure alpha-ionone. Further, the invention concerns a nucleic acid that comprises a sequence that encodes a lycopene-epsilon-cyclase (EC), a lycopene-epsilon-cyclase (EC), plasmids, which encode components of the alpha-ionone biosynthesis and a microorganism that contains heterologous nucleotide sequences which encode the enzymes geranylgeranyl-diphosphate-synthase, isopentenyl-diphosphate-isomerase (IPI), phytoene desaturase-dehydrogenase (crtI), phytoene synthase (crtB), lycopene-epsilon-cyclase (EC) and carotenoid-cleavage-dioxygenase (CCD1). Further, the invention concerns a method of producing highly pure epsilon-carotene.

  • ?-Aminocarboxylic acids, ?-aminocarboxylic acid esters, or recombinant cells which produce lactams thereof
    Patent number: 9012227
    Abstract: The present invention relates to a cell, which has been genetically modified relative to its wild type, so that in comparison with its wild type it is able to produce more ?-aminocarboxylic acids, more ?-aminocarboxylic acid esters or more lactams derived from ?-aminocarboxylic acids, starting from carboxylic acids or carboxylic acid esters. Furthermore, the present invention relates to a method for the production of a genetically modified cell, the cells obtainable by this method, a method for the production of ?-aminocarboxylic acids, of ?-aminocarboxylic acid esters or of lactams derived from ?-aminocarboxylic acids, the ?-aminocarboxylic acids, ?-aminocarboxylic acid esters or lactams derived from ?-aminocarboxylic acids obtainable by this method, a method for the production of polyamides based on ?-aminocarboxylic acids or based on lactams and the polyamides obtainable by this method.
