Abstract
The invention provides a recombinant microbial host cell capable of converting a raw material comprising a fermentable carbon substrate to o-aminobenzoate biologically. The invention further provides a method for producing aniline, comprising the steps of: a) producing o-aminobenzoate by fermentation of a raw material comprising at least one fermentable carbon substrate using the recombinant microbial host cell of the capable of converting said raw material comprising at least one fermentable carbon substrate to o-aminobenzoate biologically, wherein said o-aminobenzoate comprises anthranilate anion, b) converting said o-aminobenzoate from said anthranilate anion to anthranilic acid by acid protonation, c) recovering said anthranilic acid by precipitation or by dissolving in an organic solvent, and d) converting said anthranilic acid to aniline by thermal decarboxylation in an organic solvent.
