Culture media (CM) have been precipitated with ammonium sulphate (AmSO4) and further purified by two sequential steps of RP-HPLC chromatography on C18 and C4 columns (bacteriocin peak is marked by an arrow). The composition of the fractions representing each step of purification is illustrated by SDS-PAGE.
