    Notes: Summary Streptomyces rimosus culture filtrates after oxytetracycline production were shown to contain a number of hydrolytic enzymes in concentrations high enough to indicate their exploatation. Crude enzyme preparations were obtained using precipitation, salting out and spray-drying methods. The presence of acid, neutral, and alkaline protease and their elastolytic, esterolytic and collagenolytic activities were discerned. Substrate specificity, pH and temperature optimum, pH stability and molecular weight were studied. These proteases belonged to the group of serine and metalloenzymes. Carboxyl and thiol proteases were not present.
