Immobilization in Ionogel: A New Way to Improve the Activity and Stability of Candida antarctica Lipase B
New Candida antarctica lipase B derivatives with higher activity than the free enzyme were obtained by occlusion in an organogel of an ionic liquid (ionogel) based on the ionic liquid [Omim][PF 6 ] and polyvinyl chloride. The inclusion of glutaraldehyde as a crosslinker improved the properties of th...
