Studies on Osmophilic Yeasts

Part IX. Isolation of a New Obligate Halophilic Yeast and Some Consideration on Halophilism

Abstract

The author has isolated an obligate halophilic yeast from old soy-mash and named it Torulopsis halonitratophila nov. sp. It is of particular interest that though this yeast shows obligate halophilic property at 30° it exhibits facultative halophilism when tested at a lower temperature such as 20° This observation suggests that cultural temperature is one of the most important factors for halophilism.
