Chemical amination of lipases improves their immobilization on octyl-glyoxyl agarose beads
This paper describes a new strategy that permits to take full advantage of octyl-agarose supports to immobilize lipases (one-step purification and immobilization, stabilization of the open form of the enzyme) but that may be used in any reaction media. To this purpose, we have utilized aminated lipa...
