Popis: The influence of pH, temperature, water activity, and curing agents on germination of spores of Clostridium sporogenes (PA 3679) was examined. The most influential factor was pH; least germination occurred at pH 5.5, and most at pH 7.0, the highest pH tested. Germination occurred over a temperature range of 4 to 55 C, with maximal germination at 35 and 45 C. NaCl was more inhibitory than NaNO2 and NaNO3 at pH 7.0 at the levels used. At pH 5.5 and 6.0, NaNO2 stimulated germination.
