Summary
The keratin-degrading actinomycete Streptomyces fradiae was cultured in a bioreactor of novel design in which the wool substrate was wound over a supporting frame partially immersed in salts medium and slowly rotated during the course of fermentation. Both disulphide reductase and keratinase enzyme activities were detected in culture supernatants and the substrate was almost totally solubilized.
