  • 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
