A method for treating silage to enhance aerobic stability by inhibiting growth of yeast strains associated with spoilage of silage is disclosed. The method comprises treating silage or feed with a composition comprising killer yeast strains, or the antimicrobial components produced thereby. According to the invention, strains of <i>Saccharomyces exiguus</i> have been purified and isolated which are nontoxic, safe, do not assimilate lactate and which improve aerobic stability of silage, are disclosed. Portions of these strains have been sequenced to further characterize the invention.
L'invention porte sur un procédé de traitement de l'ensilage visant à améliorer la stabilité aérobie en inhibant la prolifération de souches de levures associées à la dégradation de l'ensilage. Ce procédé consiste à traiter l'ensilage ou les aliments pour animaux avec une composition comprenant des souches de levures mortelles, ou avec les composants antimicrobiens obtenus. Selon cette invention, des souches de <i>Sacchararomyces exiguus</i> qui ont été purifiées et isolées sont non toxiques, sans danger, n'assimilent pas le lactate et améliorent la stabilité aérobie de l'ensilage. Des parties de ces souches ont été séquencées afin de caractériser également l'invention.
