Description	Chicken feathers were processed through hydrolysis in two stages and breakdown efficiency was monitored by factor tests. In the first stage, feathers were incubated in an environment of 0.1 % or 0.3 % aqueous solution of KOH (ratio 1:50) for 24 h at 70 degrees C. After adapting pH level to 9, action by proteolytic enzyme polarzyme 12 T (1-5 %, w/w) at temperature 30-50 degrees C broke down the feathers in 4-8 h into keratin hydrolyzate. Hydrolysis of feathers in environment of 0.1 % KOH is quite low (max. 20%). In an environment of 0.3 % KOH the hydrolysis efficiency is more than four-fold. At upper limits of factors under study (8 h hydrolysis at 50 degrees C with 5 % addition of enzyme) 88.7 % feathers were degraded. Test results confirmed that applying proteolytic enzyme polarzyme 12 T achieved efficiency of chicken feather degradation similar to formerly used enzyme Savinase Ultra 16 L.
