The present invention is related to a method for the production of a dicarboxylic acid, wherein the method comprises
- a bioconversion step, wherein in the bioconversion step, the dicarboxylic acid is produced from a precursor compound contained in a medium; and a
- purification step for purifying the dicarboxylic acid from the medium, wherein the purification step comprises a nano-diafiltration step and/or a distillation step, wherein preferably if the purification step comprises both the nano-diafiltration step and the distillation step, the nano-diafiltration step is carried out prior to the distillation step, and
wherein the dicarboxylic acid is selected from the group comprising decanedioic acid, dodecanedioic acid, tetradecanedioic acid and hexadecanedioic acid, preferably the dicarboxylic acid is dodecanedioic acid (DDDA).
