摘要： The present invention concerns a microbiological process for the production of γ-decalactone. According to this process, a culture of the fungus of a particular species of the genus Mucor is incubated with the particular substrate, which is an organic carboxylic acid ester, to produce fermentatively the γ-decalactone. According to the invention, exact conditions have now been discovered under which γ-decalactone can be prepared in high yields. These conditions are based upon the fermentative incubation of a fungus of the genus Mucor in conjunction with the appropriate substrate in order to obtain the high yield of the desired lactone.

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.
