Abstract: | The influence of growth parameters on the production of pediocin AcH by Pediococcus acidilactici H was studied. This strain produced large quantities of pediocin AcH in TGE broth (Trypticase 1%], glucose 1%], yeast extract 1%], Tween 80 0.2%], Mn2+ 0.033 mM], Mg2+ 0.02 mM] pH 6.5]) within 16 to 18 h at 30 to 37°C (final pH, 3.6 to 3.7). Pediocin AcH production was negligible when the pH of the medium was maintained at 5.0 or above, even in the presence of high cell mass. |
