Abstract

Populations of fungi in aerobically deteriorating wheat and alfalfa silages were identified as: Endomycopsis burtonii, E. selenospora, Hansenula canadensis, Candida tenuis and C. silvicola. The yeasts recovered were similar for both silages, but H. canadensis was recovered only in wheat silages. All of these yeasts could utilize lactic acid aerobically, but not anaerobically. Only Endomycopsis spp. could utilize propionic acid aerobically and none of the yeasts utilized this acid anaerobically. However, all yeasts grew in complete media supplemented with propionate. Therefore, while lactic and propionic acids may contribute to stability under anaerobic conditions, they are much less less effective after the silage is exposed to air.
