Electrophoretic and zymographic techniques for production monitoring of two lipase forms from Candida antarctica DSM 70725
Yeast Candida antarctica produces two lipase forms, which are widely used as catalysts in variety of organic reactions, many of which are applied on a large scale. In this work, production of two forms of lipase from C. antarctica DSM 70725 (CAL A and CAL B) was monitored during seven days of cultiv...
