Abstract: Conversion of organic educts, in particular biomass feedstock, into useful organic compounds via pyrolysis and bio-catalysts.

Abstract: The present invention relates to the field of biotechnology. It involves the decomposition and conversion of organic educts, in particular biomass feedstock, lignin, guaiacol; p-coumaryl alcohol; coniferyl alcohol; sinapyl alcohol; cresol; phenol; catechol; polysaccharides; cellulose hemicellulose; xylose; glucose; fructose; proteins; amino acids; triacylglycerides and/or fatty acids into useful organic compounds with the help of biocatalysts. A method of producing an organic product comprises i) fluid-assisted decomposition of an organic educt under sub- or supercritical conditions ii) obtaining an intermediate product from step i) iii) subjecting the intermediate product to biocatalytic conversion, by contacting the intermediate product obtained in step ii) with a biocatalyst, wherein said biocatalyst is a host cell selected from the group consisting of bacteria, yeast, filamentous fungi, cyanobacteria, algae, and plant cells.
