Cultivation conditions and properties of extracellular crude lipase from the psychrotrophic fungus Penicillium chrysogenum 9′

Abstract: Among 97 fungal strains isolated from soil collected in the arctic tundra (Spitsbergen), Penicillium chrysogenum 9' was found to be the best lipase producer. The maximum lipase activity was 68 units mL(-1) culture medium on the fifth day of incubation at pH 6.0 and 20 degrees C. Therefore, P. chrysogenum 9' was classified as a psychrotrophic microorganism. The non-specific extracellular lipase showed a maximum activity at 30 degrees C and pH 5.0 for natural oils or at pH 7.0 for synthetic substrates. Tributyri… Show more

“…The metalchelating agent EDTA and the esterase inhibitor, eserine, appeared to have no signiWcant eVect on B. adusta R59 lipase activity at the concentrations tested, indicating that the lipase is not dependent on a metal cofactor at its active site (Table 4). In contrast, lipases from Flavobacterium odoratum [18] and Penicillium chrysogenum 9Ј [4] are metal-dependent enzymes.…”
