Abstract
Thirty-three strains of anaerobic bacteria isolated from human clinical specimens were examined for the presence of heparinase, hyaluronidase, chondroitin sulfatase, gelatinase, collagenase, fibrinolysin, lecithinase and lipase activities. Pronounced heparinase activity was limited to species of Bacteroides. A number of species of Bacteroides and Clostridium produced hyaluronidase and chondroitin sulfatase. Gelatinase, collagenase and fibrinolysin activities were encountered in isolates of Bacteroides, Clostridium and Peptostreptococcus. All strains capable of degrading collagen also hydrolyzed other protein substrates. Lipolytic activity was minimal among these anaerobic bacteria. No specific hydrolytic activity was consistently associated with the isolates.
