Chemically Defined Medium for Growth and Sporulation of Clostridium perfringens

Abstract

A chemically defined medium was developed that could support sporulation and growth of Clostridium perfringens strains ATCC 12916 and H9. This medium consisted of a modification of the basal medium of Boyd et al. plus 0.1% sodium thioglycolate and 0.5% monosodium glutamate. Five other strains grew, but did not sporulate, in this medium. With the addition of more vatamins into the medium, two more strains grew but did not sporulate. The effects of glucose, monosodium glutamate, ammonium glutamate, and sodium thioglycolate on growth and sporulation of C. perfringens ATCC 12916 in the defined medium was investigated. Images
