RESUMO
The heat resistances of the fully demineralized H-form spores of Bacillus megaterium ATCC 19213, B. subtilis var. niger, and B. stearothermophilus ATCC 7953 were compared with those of vegetative cells and native spores to assess the components of resistance due to the mineral-free spore state, presumably mainly from dehydration of the spore core, and to mineralization. Mineralization greatly increased heat resistance at lower killing temperatures but appeared to have much less effect at higher ones.
