General description

A selective supplement recommended by ISO Committee for the isolation of Listeria species.
Chemical structure: peptide

Application

for the isolation of Listeria species

Biochem/physiol Actions

Mode of Action: Polymyxin B Sulfate binds to the lipid A portion of bacterial lipopolysaccharides†, disrupting the cytoplasmic membrane by inducing pores large enough to permit nucleotide leakage in bacterial walls. This disrupts the permeability of the cytoplasmic membrane.

Antimicrobial spectrum: Has bactericidal action on most gram-negative bacilli††, including E. Coli and on most fungi and gram-positive bacteria.
