| Abstract: | The action of lysozyme on the enterococcal cell differed markedly as a function of the ionic strength of the environment. In high ionic environments (I ![similar, equals]](corehtml/pmc/pmcents/sime.gif) 0.3), the traditionally slow lytic response and decrease in viability were noted. In a low ionic environment the majority of the cell wall was hydrolyzed, but cellular integrity was preserved and almost all cellular protein, deoxyribonucleic acid and ribonucleic acid remained with the lysozyme-cell complex. However, under these conditions, lysozyme inactivated energy-yielding metabolism, and a rapid extensive loss of viability was observed. Some other basic compounds without lytic activity on the cell wall also effected a substantial reduction in viability. The data suggest that lysozyme acts on the cell membrane to effect disruption of cellular metabolism. |
