متن کاملBacteriolytic activity in staphylococci.
The bacteriolytic activity of Staphylococcus aureus and Staphylococcus albus strains was tested with various media. Whereas S. aureus strains were found to be active under all conditions, the percentage of active S. albus strains was significantly influenced by the composition of the medium. Ionic strength and concentration of the organic nitrogen source were found to be the main factors affect...

15 صفحه اولBacteriolytic Enzymes from Streptomycetes
A study of the bacteriolytic properties of streptomycetes has progressively uncovered the production by these microorganisms of a large number of different enzymes acting upon various bacterial constituents, especially on some of them located in the cell wall. Although the mechanism of the bacteriolysis is far from being completely elucidated at present, it can, however, be stated that, in two ...
متن کاملBacteriolytic action of fluoride ions.
Bacillus subtilis, Neisseria subflava, and LYT coccus were found to undergo massive lysis after growth in media containing 0.01 to 10 mM NaF. When cells of these organisms were transferred from late-exponential-phase cultures to 0.02 M sodium phosphate buffer plus 0.1 M KCl, they underwent spontaneous autolysis. Cells grown in media with fluoride were more liable to autolysis, and walls isolate...
