Abstract: Bioconversion of ferulic acid from residue of rice bran oil into vanillin with Aspergillus niger CGMCC0774 and Pycnoporus cinnabarinus CGMCC1115 was studied. The mutant strain, which resisted high substrate concentration and could not degrade the product was obtained by 60Co irradiation to produce 2.48g/L vanillic acid enriched broth. The vanillic acid enriched broth was converted into 1.07g/L vanillin by Pycnoporus cinnabarinus CGMCC1115 cells under the following conditions: glucose 5g/L and pH5.0. It showed that the combining bioconversion of Aspergillus niger CGMCC0774 and Pycnoporus cinnabarinus CGMCC1115 of ferulic acid to vanillin is feasible.
