【 摘 要 】

Enzymes are biological catalysts that offer great potential for use in the synthesis and modification of polymers, being more specific and greener than chemical catalysts. In this work, enzymes from the classes of hydrolases (lipase, cutinase and protease) and of oxidoreductases (horseradish peroxidase, manganese peroxidase and laccase) were identified as the main biocatalysts responsible for the synthesis of polymers. Biocatalysis can potentially be part of the life cycle of several polymers, including polyesters, polyurethanes, polycarbonates, polyamides, functionalized polysaccharides and polystyrene, allowing the synthesis of specialty macromolecules for fine applications and with higher added-value than commodity polymers.
