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.

Abstract: The invention relates to a method for producing aniline, comprising the steps of: a) providing o-aminobenzoate, wherein said o-aminobenzoate comprises anthranilate anion and a suitable cation, b) converting said anthranilate anion to aniline by thermal decarboxylation in the presence or absence of a catalyst, c) extracting the aniline produced in step b) in an organic solvent at least once, and d) purifying the aniline produced in steps b) and c) by distillation, wherein said distillation produces aniline and a water phase.

Abstract: The invention relates to a separator for retaining and recirculating cells in a continuous-flow or batch-flow type plastic bag or bottle, which can preferably be operated outside of a bioreactor. Additionally, the invention relates to a method for retaining and recirculating cells within or outside a bioreactor. The invention further relates to a method for producing the separator according to the invention.
