Enzymatic synthesis of vanillin.
Due to increasing interest in natural vanillin, two enzymatic routes for the synthesis of vanillin were developed. The flavoprotein vanillyl alcohol oxidase (VAO) acts on a wide range of phenolic compounds and converts both creosol and vanillylamine to vanillin with high yield. The VAO-mediated conversion of creosol proceeds via a two-step process in which the initially formed vanillyl alcohol ...
متن کاملBiocatalytic synthesis of vanillin.
The conversions of vanillic acid and O-benzylvanillic acid to vanillin were examined by using whole cells and enzyme preparations of Nocardia sp. strain NRRL 5646. With growing cultures, vanillic acid was decarboxylated (69% yield) to guaiacol and reduced (11% yield) to vanillyl alcohol. In resting Nocardia cells in buffer, 4-O-benzylvanillic acid was converted to the corresponding alcohol prod...
متن کاملEnzymatic and chemo-enzymatic synthesis of carbohydrates
Carbohydrate-mediated biochemical recognition processes are potential targets for drug development. The synthesis of complex carbohydrates and related structures, however, has been a difficult task, especially from practical point of view. New solutionand solidphase methods based on enzymatic and a combined enzymatic and chemical procedure have recently been developed for the practical synthesi...
متن کاملEnzymatic Synthesis of Carotenes
The pathway of carotene biosynthesis from isopentenyl pyrophosphate in tomato fruit plastids has been established, except for minor details, through the conversion of radioactive sub— strates and intermediates to acyclic and cyclic carotenes in cell—free systems. After the pathway of carotene biosynthesis was established attention was turned to the isola— tion and purification of enzymes of car...
متن کاملEnzymatic synthesis of biodiesel
Lipases offer interesting perspectives as biocatalysts for the biodiesel synthesis, though their application is still limited by the poor stability of the enzyme at the operating conditions of industrial interest. In order to overcome this bottleneck, the inactivating effect of specific components of the methanolysis reacting system has been characterised, to develop a rational stabilization st...
