Process for the production of ortho-aminobenzoic acid and/or aniline by using recombinant yeast

A method for producing o-aminobenzoic acid comprising the steps of

• a) fermenting at least one fermentable substrate in a fermentation vessel using a yeast cell capable of converting the at least one fermentable substrate into o-aminobenzoic acid;
• and
• b) separating the produced o-aminobenzoic acid from the fermentation broth.

A recombinant yeast cell comprising a modification of anthranilate phosphoribosyltransferase activity which decreases the activity of said enzyme.
