Abstract
THE wide range in the heat resistance of bacterial spores in dilute neutral solutions is well known but still unexplained. Studies of spores having a wide range of heat resistance (greater than 104-fold) in phosphate buffer (0.05M, pH 7) have shown that these differences in heat resistance largely disappear when the spores are heated in a substantially dry state.
