The Fermentation of Malt Extract by an Osmophilic Yeast [PDF]

Journal of General Microbiology, 1953
SUMMARY: The fermentation of malt extract by the osmophilic yeast Saccharomyces rouxii Boutroux is described. It is found that the limiting factor determining whether an extract will ferment or not is its relative humidity, the critical level of which is about 73%.
