| Abstract: | Pycnoporus cinnabarinus SW-0203 was screened for bioconversion of vanillic acid to vanillin. At the optimum fermentation conditions, it transforms 1.682 g/L vanillic acid to 0.875*#g/L vanillin with a molar yield of 57.5%. 0.818*#g/L vanillin was obtained with a molar yield of 53.7% in 25 Lfermentor. Vanillin was extracted and its purity was 95% with a yield of 63.9%. |
