OPTIMIZATION OF THE NUTRITIVE MEDIUM FOR CULTIVATION OF

PENICILLIUM funiculosum – A SOURCE OF CATALASE

Enzymatic biosynthesis of microorganisms is directly influenced by nutrient components. Using the mathematical programming model, it has been established that culture medium of Penicillium funiculosum CNMN FD 11 for maximum biosynthesis of catalase is (g/l): KNO3 – 7,4; glucose – 40,0; NaH2PO4 – 2,5; K2HPO4 – 2,5; MgSO4 x 7H2O – 0,05; FeSO4 x 7H2O – 0,055 and yeast extract – 18,5 ml; microelements – 1,0 ml, initial pH – 6,6.

Keywords: nitrogen, carbon, strain, culture medium, catalase activity
