CalB immo 1090 was jointly developed and is co-marketed by c-LEcta and Purolite.
Immobilized, recombinant Lipase B from Candida antarctica (CalB) produced by microbial fermentation with Pichia pastoris. CalB immo 1090 is an adsorbed preparation and is suitable for applications in solvent-free systems like oils, as well as organic solvents and it and can be used for (regio- and stereoselective) esterifications and transesterifications. The lipase is immobilized by adsorption through interaction of hydrophobic surface of lipase with aromatic rings of Purolite’s highly hydrophobic carrier Purolite ECR1090M (styrene/DVB co-polymer).
CalB Immo 1090 has many advantages compared to similar commercial preparations:
- high activity
- possibility to use in oils, organic solvent and bi-phasic systems
- security of supply from kg to ton scale
- full regulatory support
