| 摘要 |
The present invention concerns a microbiological process for the production of vanillin, comprising cultivating in a nutrient broth of a bacterium belonging to the order of the Actinomycetales, preferably of the family Streptomycetaceae, adding the substrate ferulic acid, wherein the substrate concentration in the nutrient broth is from about 5 gL<-1> to about 40 gL<-1> in the fermentation broth, producing vanillin as the main reaction product of the biotransformation of ferulic acid and separating the biomass from the fermentation broth, and extracting the vanillin and, if desired, the by-product guaiacol from the fermentation broth. |
