ABSTRACT

The bacteriocin, lacticin 3147, increased isoleucine transamination by Lactococcus lactis IFPL359 in a cheese model system. The formation of alpha-keto-beta-methyl-n-valeric acid and 2-hydroxy-3-methyl-valeric acid increased by three times in cheese slurries at 12 degrees C and cheese aroma intensity increased as well, which corresponded with a higher 2-methylbutanal formation.
