  • Patent number: 10767198
    Abstract: A method for producing branched aldehydes is proposed, the method comprising the following steps: (a) providing a culture of one or more fungi of the genus Conidiobolus and producing biomass containing branched carboxylic acids in free and/or bound form; (b) extracting the biomass from step (a) to produce a first intermediate containing free and/or bound carboxylic acids; (c) optionally chemically, enzymatically or microbially hydrolyzing the bound carboxylic acids from the first intermediate; (d) treating the first intermediate with a reducing agent of a chemical nature to convert the free and/or bound carboxylic acids into the corresponding alcohols and optionally separating one or more alcohols from interfering by-products and producing the chemically produced second intermediate containing these alcohols as a mixture or in enriched form; (e) treating the first intermediate with a reducing agent of a biological nature to convert the free and/or bound carboxylic acids into the corresponding aldehydes havin

  • Patent number: 10538797
    Abstract: The invention relates to a method for producing flavone glycoside dihydrochalcones, having the following steps: (a) providing a transgenic microorganism containing (i) a first nucleic acid portion (A) containing a gene which codes for a bacterial chalcone isomerase and (ii) a second nucleic acid portion (B) containing a gene which codes for a bacterial enoate reductase, (b) adding one or more flavone glycosides to the transgenic microorganism under conditions which allow the simultaneous isomerization and reduction of the flavone glycoside into the flavone glycoside dihydrochalcone, and optionally (d) isolating and purifying the final product, wherein the nucleic acid portion (A) (1) is a nucleotide sequence according to SEQ ID NO:1, in which the nucleic acid portion (A?) according to SEQ ID NO:3 has been cut out, or (2) is an amino acid sequence according to SEQ ID NO:2, in which the amino acid portion (A?) according to SEQ ID NO:4 has been cut out.

  • Patent number: 6803244
    Abstract: In a nanostructured reactive substance and a process for producing the same, intermixing of silicon and oxidizing agent on a nanometer size scale permits virtually direct contact between the fuel and the oxidizing agent, only separated by a barrier layer. After the barrier layer is broken open, fuel and oxidizing agent are spatially directly together and can react, liberating energy. The reactive substance has a high reaction rate in comparison with conventional reactive materials.
