Partially hydrolyzed extracts from blood meal, feather meal, and meat and bone meal, as well as a variety of common surplus agricultural proteins were tested for their ability to promote the flocculation of clay. Partial alkaline or enzymatic hydrolyses of blood meal, feather meal, and meat and bone meal were performed to liberate proteins and peptides from their water-insoluble forms. Some of these extracts promoted flocculation. However, if hydrolysis was extensive, low molecular weight peptides were mainly produced, and these extracts did not promote flocculation. Beef skin gelatins and hydrolyzed fish collagen were found to promote flocculation when pH 5.5 buffer was added. Commercial preparations of peptone enzymatic digest and a mixture of keratin and hydrolyzed keratin did not promote flocculation.
