Hydrolytic enzymes of anaerobic bacteria isolated from human infections.
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 the genus Bacteroides. A number of species of the genera Bacteroides and Clostridium produced hyaluronidase and chondroitin sulfatase. Gelatinase, collagenase, and fibrinolysin activities were encountered in isolates of the genera 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.
