Culture course of K. rhizophila p3-3 in feather-containing medium. Proteolytic activity and accumulation of hydrolysis products were determined during culture of K. rhizophila p3-3 in the presence of 1% (w/v) feathers in agitated culture. Diamonds indicate protein concentration; circles indicate concentration of amino acids; triangles indicate proteolytic activity; squares indicate concentration of reduced thiols
