[Bacteriocins of Clostridium septicum (author's transl)].
17 strains of Clostridium septicum were examined for bacteriocin production. Two bacteriocin-producing strains were detected by the stab culture method and the spot test using the supernatant fluids of the cultures. The bacteriocin of Cl. septicum Ovinus was active against all other strains of Cl. septicum without inhibiting the donro strain (Table 2). This bacteriocin and one indicator strain (Wex) were chosen for further study. The bacteriocin, which was spontaneously produced during the logarithmic growth phase of the bacteriocinogenic strain Ovinus (Fig. 1) was not inducible with high temperatures or Mitomycin C. It was resistent to chloroform, but sensitive to heat (Fig. 4, 5) and proteolytic enzymes (Table 4). Its MG is about 20000 (Fig. 3).
