چکیده انگلیسی
A Scopulariopsis brevicaulis poultry farm isolate was chosen to study factors influencing keratinase production. The parameters were optimized by factorial design. The highest enzyme production by this fungus was obtained at pH 7.5, a temperature of 30 °C and a growth period of 5 weeks. The production of the enzyme was enhanced when the culture medium was supplemented with glucose (1%), sodium nitrate (2%), feather (1.5%) and CaCl2 (1 mM). According to the responses from the experimental design, the effects of each variable were calculated, and the interactions between them were determined. The experimental values were found to be in accordance with the predicted values, the correlation coefficient is 0.9978.
