  • Patent number: 11168341
    Abstract: The invention relates to a method for producing aminobenzoic acid or a aminobenzoic acid derivative via the fermentation of a suitable raw material under the influence of suitable microorganisms and obtaining a fermentation broth containing aminobenzoate and/or aminobenzoic acid. In particular, the invention relates to the step of obtaining the aminobenzoic acid from the fermentation broth, wherein the crystallisation of aminobenzoic acid is carried out via a simple one-stage acid treatment in the presence of seed crystals. The aminobenzoic acid crystallised in this simple manner can be easily separated from the mother liquor, further cleaned if necessary, and then supplied to the different applications.

  • Patent number: 10731187
    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.
