Abstract:

The relative effect of concentrated solutions of selected glass formers on germination time at 28 °C of mold spores of Aspergillus flavus, A. niger and Eurotium herbariorum was determined. Solutes included glucose, fructose, mannose, glycerol, sucrose, maltose and propylene glycol. The effect of fructose concentration on the germination time of A. parasitions was also studied. The results did not agree with previous literature experimental data used to support a 'water dynamics' approach of microbial stabilization in concentrated sugar and polyol solutions. © 1996.
