Abstract:

Chloroperoxidase from Caldariomyces fumago catalyses the oxidation of 1,2-dihydronaphthalene to (1R,2R)-(+)-dihydroxytetrahydronaphthalene in homogenous citrate buffer/ionic liquid mixtures, using t-butyl hydroperoxide as O2 donor. It tolerates up to 30 (v/v) 1,3-dimethylimidazolium methylsulfate or 1-butyl-3-methylimidazolium methylsulfate. The enzyme activity in these ionic liquid co-solvent systems is retained for 24 h, but it falls to 3 h using non-ionic organic solvents such as t-BuOH or acetone.
