Antimicrobial activity of the supernatant (>10 kDa fraction of the cell-free supernatant) of SF214 on L. monocytogenes cells. (a) Different amounts of supernatant were added during growth at the time indicated by the black arrow. The red arrow indicates the time of collection of cells to test Antimicrobial activity on resting cells (see text). (b) MTT assay performed on L. monocytogenes cell without any supplementation (Control) or supplemented with the >10 or <10 kDa fractions of the SF214 cell-free supernatant
