Abstract
Spores in adequate quantity for heat resistance testing were produced in chemically defined media by two strains of B. cereus. Resistance was not affected by any one of the amino acids, growth factors, or yeast nucleic acid as nutrients. Resistance was independent of the luxuriance of growth and of the luxuriance of sporulation. The test strains did not grow unless valine was present in the medium.Keywords
