The invention relates to novel protective cultures, containing lactic acid-producing
bacteria for preserving foodstuffs or animal feed, which can only be conserved
for a limited period of time, even under refrigeration. The protective cultures
can inhibit the growth of bacteria which are dangerous to the consumer, if the
cold chain is interrupted, or if the prescribed cooling temperature is exceeded.
The invention further relates to foodstuffs or animal feed which contain the inventive
protective cultures. The strain Lactococcus lactis subsp. lactis 1526
is specifically provided.
