Figure 6From: Design of an efficient medium for heterologous protein production in Yarrowia lipolytica: case of human interferon alpha 2bInfluence of mineral ions on the proteolytic activity (pro) (U/ml) of Y. lipolytica. H3BO3(h3); CuSO4.5H2O (cu); KI(k); MnSO4.2H2O (mn); FeSO4.7H2O (fe); Na2MoO4.2H2O (na); CoCl2.6H2O (co) and ZnCl2 (zn) were added at different combination to the colorimetric reaction for proteolysis activity determination using azocasein as substrate. (a) absence, (p) presence. Results are mean values of two independent repeat of 67 experiments. *indicates trace-elements and interactions that have an inhibitory effect on the proteolytic activity of Y. lipolyticaBack to article page
