Conclusions
-
1.
Yeasts are destroyed when exposed directly to the effects of ultraviolet light.
-
2.
Irradiation of dextrose-broth cultures of fermenting yeasts in quartz apparatus for periods of time totaling 1 hour and 20 minutes seriously inhibited their fermenting ability.
-
3.
Exposure of yeasts in aqueous suspension to ultraviolet light destroyed so many cells that no gas was formed in 24 hours; very small amounts were formed in 31 hours. The non-irradiated controls showed regular active gas formation.
-
4.
Exposure of dextrose broth cultures to ultraviolet light, after fermentation had begun, greatly inhibited gas formation.
-
5.
Dextrose broth irradiated for a long time before inoculation tended to ferment more slowly than the non-irradiated control media.
-
6.
No observations were made to indicate that exposure of yeasts or media to ultraviolet before inoculation increased the amount of gas formed.
