Quite pure KpneM, KpneM2 and KvarM proteins were obtained after single-step hydrophobic interaction chromatography (HIC), but for best results a second purification step by anion exchange chromatography was included. The constructions were transformed into StellarTM competent cells and colonies were selected on LB agar plates containing 50 μg/ml of ampicillin and 0.

We thus demonstrated that all three M-type klebicins KpneM, KpneM2 and KvarM are translocated by the mechanism similar to that of colicin M and that they need the FhuA receptor and TonB-related translocation pathway to enter the periplasm and exert their activity 20, 26.

Further broad studies on resistance mutation frequencies are necessary to assess the practical utility of bacteriocins as antibiotic alternatives. Bacterial biofilms were formed by immersing the pegs of the biofilm detection lid, a modified polystyrene microtiter lid (Nunc TSP system), into the wells of the biofilm growth plate, followed by incubation at 30 °C or 37 °C for 20 h. For treatment with klebicins, peg biofilm detection lids were rinsed three times in sterile water, placed into microtiter plates containing 5 µg/ml of klebicins diluted in 100 µl CAA per well and incubated for 5 h at 30 °C or 37 °C, depending on the strain.

Our data seem to indicate that the way forward would be the use of bacteriocin cocktails that combine proteins with different receptor/translocation routes, as well as the use of bacteriocins specifically engineered for low resistance frequency.
