Abstract

Antibacterial action of protamine combined with monocaprin against E. coliwas investigated. The growth of E. coli was inhibited by protamine strongly at higher concentrations, and at levels greater than 0.05% (w/w), protamine perfectly suppressed the growth of E. coli during SOC-incubation for 44 h. Monocaprin showed higher antibacterial activity than any other reagents in the presence of protamine (0.003% w/w). The combined use of protamine and monocaprin greatly suppressed the growth of E. coli during incubation at various temperatures (20-40 degrees). The suitable pH for antibacterial action of protamine combined with monocaprin was in the pH region of 5-7. Protamine more actively prevented the colony-formation of E. coli than monocaprin. Cell-surface hydrophobicity of E. coli increased by the addition of protamine. Monocaprin caused a leakage of UV-absorbing substances from E. coliSuccinate dehydrogenase activity in the E. coli cell membrane was rapidly reduced by the addition of protamine combined with monocaprin.
