Method of degrading keratinaceous material and bacteria useful therefore
United States Patent 4959311
A method of degrading keratinaceous material is disclosed. The method comprises the steps of combining the keratinaceous material with Bacillus licheniformis to form a fermentation media and then fermenting the media for a time sufficient to degrade the material. The method can be used to produce amino acids from keratinaceous material and to produce a hydrolyzed feather product useful as a feed additive from the keratinaceous material.

A preferred keratinaceous material for carrying out the present invention is feather, and a preferred bacteria for carrying out the invention is Bacillus licheniformis PWD-1.
