SALES, Marilia Ribeiro et al. The use of poultry feather to produce keratinase by Aspergillus carbonarius. Pesq. agropec. bras. [online]. 2008, vol.43, n.2, pp. 285-288. ISSN 0100-204X. http://dx.doi.org/10.1590/S0100-204X2008000200020.
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.
