Abstract

Summary: , when growing exponentially in batch culture, passed through a phase in which, on average, one cell in 10 survived plating onto a low water activity ( ) agar medium. Stationary phase cultures were resistant as were all other species tested, with the exception of . In continuous culture, was more resistant at low than at high dilution rates. Plating at low was lethal to those cells that were not protected by an adequate content of compatible solute. In naturally resistant yeasts and in that had been exposed to an adaptation process, the compatible solute was one or more types of polyhydric alcohol. Resistance in stationary phase was attributable to a different cause.
