Studies in the Physiology of Clostridium Botulinum Type E

Abstract

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.
