Abstract: The present invention relates to Lactococcus starter cultures that are compatible with nisin-producing strains and simultaneously do not degrade nisin. The present invention defines starter cultures that can be used in combination with nisin-producing cultures, without degradation of nisin. Furthermore, it is also disclosed that starter cultures can be made by a combination of nisin-producing strains and strains containing nisin-immunity genes and/or and absent of the gene to prevent degradation of nisin.
