additional information | immobilization of feruloyl esterase on mesoporous silica as support. Immobilization in mesoporous silica with larger pore size of 9 nm shows higher protein loading and higher specific activity compared to immobilization with smaller pore size of 5 nm. Adsorption into mesoporous silica changes the product specificity of the enzymes to favor transesterification and decrease the rate of hydrolysis compared to free enzymes, overview. The immobilized enzyme has a butyl ferulate yield of up to 90%, significantly higher compared to free enzyme. Additionally, the immobilized enzymes shows an excellent operational stability and reusability, retaining 70% or more of the initial activity after 6 sequential runs, each lasting 6 days | Humicola sp. |
