Kinetic Study of Enzymatic Oxidation On Glycerol with Immobilised Laccase/TEMPO System
Glycerol, a byproduct of biodiesel has a great potential in producing valuable fine chemicals. Current catalytic oxidation methods based on noble metal have their drawbacks on environment. Towards this end, an enzymatic oxidation of glycerol by laccase from Trametes Versicolor and TEMPO (2,2,6,6-tet...
