Collagenolytic activity of bacteria.
Actively growing aerobic and anaerobic bacteria were screened by a plate assay, with reconstituted guinea pig collagen as a substrate, for their ability to produce a collagenolytic factor. Collagenolytic activity was not demonstrated among the aerobic organisms tested, with the exception of one strain of Staphylococcus aureus (only when grown under anaerobic conditions). Collagenolytic activity...
متن کاملCollagenolytic activity of Coccidioides immitis.
Coccidioides immitis appears to be unable to digest particulate collagen when cultured on collagen-containing semisolid culture media. However, all C. immitis strains solubilized collagen when the fungus was grown in liquid suspension cultures. Moreover, sterile culture filtrates were collagenolytic in collagen-buffer-agar plate assays.
متن کاملIsolation of extreme halophiles from seawater.
Extreme halophilic bacteria were isolated from the ocean off the coast of Spain. All were gram-negative cocci. One isolate was compared to Halococcus sp. NCMB 757 and was found to have similar characteristics.
متن کاملCollagenolytic Activity in Rat Bone Cells
An assay system for estimating quantitatively collagenase-like activity present in bone cells has been developed as part of a more general investigation of mechanisms of bone resorption. Methods are described for preparing from bone a C(14)-labeled collagen which is relatively pure and highly resistant to degradation by trypsin although readily broken down by bacterial collagenase. Collagenolyt...
متن کاملColiforms from hides and meat.
Coliform tests were performed on 85 hide and 75 meat samples. IMViC reactions were determined on isolates from positive confirmed and fecal tests, and strains other than Escherichia coli were identified. Strains typed as Aerobacter aerogenes types I and II were identified as Enterobacter cloacae (51.4%), Klebsiella pneumoniae (21.5%), Enterobacter aerogenes (15%), and Enterobacter liquefaciens,...
