HEAT ADAPTATION AND ION EXCHANGE IN BACILLUS MEGATERIUM SPORES.

G ALDERTON, P A THOMPSON, N SNELL.   

Abstract

A new spore phenomenon is described in which induction of increased heat resistance occurs during the process of heating. In buffered environments the acid form of dormant mature bacterial spores shows a temperature dependent adaptation to heat which is correlated with the rate of uptake of Ca(OH)(2) by titration at constant p(H) in neutral salt solution.
