His‐Tag Immobilization of Cutinase 1 From Thermobifida cellulosilytica for Solvent‐Free Synthesis of Polyesters
For many years, lipase B from Candida antarctica (CaLB) was the primary biocatalyst used for enzymatic esterification and polycondensation reactions. More recently, the need for novel biocatalysts with different selectivity has arisen in the biotechnology and biocatalysis fields. The present work de...
