Notes:
TPGY medium was acidified to pH 4.20, 4.60, 5.00 and 5.40 with acetic or citric acid. The media were inoculated with spores from three strains of C. botulinum type A, B or E. Growth, pH, and toxin production under anaerobic conditions were monitored for 8 wk. Spores of C. botulinum types A and B were incapable of outgrowth and toxin production at pH 4.60 or below when incubated at 35°C. Spores of C. botulinum type E were capable of growth and toxin production at 26°C in citric acid acidified systems at pH 4.20. Growth and toxin production were not detected below pH 5.00 when acetic acid was used.
