Low heat resistance of Bacillus sphaericus spores correlated with high protoplast water content.
The low heat resistance (D100 = 0.554 min, z = 13.4 degrees C) of dormant lysozyme-sensitized spores of Bacillus sphaericus 9602 was correlated with a low protoplast wet density (1.305 g/ml) equivalent to a high protoplast water content (61.0%, wet weight basis). These values for these unusual spores were consistent with those correlated previously in 28 spore types of seven other species.
