Abstract

The objective of this work was to evaluate the keratinase production by Aspergillus carbonarius URM 1546, using as substrate poultry feather in a full experimental design 23. The studied parameters and the second-order interactions were statistically significant. The maximum keratinase activity (48.9 U mL-1) was obtained using 120 rpm, with 0.5% (w/v) poultry feather and seven culture days.
