We have investigated the feasibility of controlling
spoilage bacteria during wine fermentations by
engineering bactericidal strains of S. cerevisiae. To
test this novel concept, we have successfully
expressed two bacteriocin genes in yeast, the one
encoding a pediocin and the other a leucocin [137].
The pediocin gene originates from Pediococcus acidilactici PAC1e0 [188] and the leucocin gene
from Leuconostoc carnosum B-Ta11a [34].
