Depolymerization of lignin

A possible reductive role for veratryl alcohol oxidase is proposed in Figure 5. Laccases from C. versicolor can produce both polymerization and depolymerization of lignin (29). In phenolic lignin model dimers, laccase can perform the same electron abstraction and subsequent bond cleavage as found for lignin peroxidase (30). The phenolic radical is however likely to polymerize unless the quinoid-type intermediates can be removed, for example by reduction back to the phenol. Veratryl alcohol oxidase, in... [Pg.477]

The simulation model development is divided into three sections. The first discusses the probabilistic modelling of lignin structure, and the use of probability distribution functions to generate representative lignin moieties. The second section details the depolymerization of lignin using stochastic kinetics. The final portion describes the combination of these elements into a Monte Carlo simulation and also presents representative predictions... [Pg.242]

In addition, biotech processes are also efficient in order to perform chemical modifications of vegetable fatty acids such as regioselective hydroxylation. Glycerol can also be used as feedstock in fermentation processes and lead to the production of chemicals of interest. More efforts could be developed to perform the depolymerization of lignin by biochemical ways. [Pg.259]
