Rates Of Growth

Ten strains of Clostridium botulinum type E have been studied at 12 temperatures between 2�5 and 45�0. Growth proceeded consistently from spore inocula at temperatures between 5 and 37�5�0, but some strains developed slightly at ~empera� tures up to 45�0. Maximum rates of growth occurred at 35�0. The upper and lower temperature limits were several degrees lower than for type A and B strains.

Rates Of Growth

Ten strains of Cl. botulinum, type A, and 10 of type B have been studied at 12 temperatures between 10 and 50�C., and rates of growth measured nephelometrically on sealed cultures. Growth proceeded from spore inocula at temperatures from 15 through to 42.5�C., but not at 12.5 or 45�C. When young, actively growing cultures were transferred to temperatures outside the range permitting spore germination, rates of growth were measured at 12.5, 45, and 47.5�C. After transfer to 10 or 50�C. no sustained growth was observed

The effect of salt level and nitrite on botulinal safety of smoked whitefish was investigated. An average water-phase (wp) salt concentration of 4.4% inhibited outgrowth of Clostridium botulinum type E spores (103 spores/g) for over 35 d in temperature-abused (27°C) smoked whitefish. Incorporation of nitrite (220 mg/kg) during brining to the smoked salted (4.4%, wp) whitefish inhibited toxin production for 56 d at 27°C. An average salt concentration of 6.2% (wp), with or without nitrite, totally inhibited toxin production for the duration of the study (83 d). The effect of pH and water activity in temperature-abused smoked whitefish as a means of controlling toxin production by C. botulinum type E spores was evaluated.
