Abstract
Summary. Aqueous spore suspensions of Clostridium aerofoetidum, Cl. caloritolerans, Cl. histolyticum, Cl. sordellii, Cl. sporogenes and Cl. subterminale were heated at temperatures within the range 70–95†C. 80†C for 1 hr was without effect on Cl. aerofoetidum, but reduced Cl. caloritolerans, Cl. histolyticum and Cl. sporogenes to about 25% of the initial count, and Cl. sordellii and Cl. subterminale to about 0.01%. No significant heat‐activation was detected. Not all survivor curves were exponential.Keywords
