Effect of benzylpenicillin on the viability and osmotic sensitivity of Listeria monocytogenes.
Growth in the presence of 100 ppm benzylpenicillin (BP) for 2 h failed to result in a detectable reduction in cfu. Cells grown and incubated for 24 h in 0, 1, 10 and 100 ppm BP underwent reductions in cfu of 0%, 0%, 90% and 99% respectively of maximum cfu values.
