Used extensively in soft cheese production. Lactococcus lactis subsp. lactis Il1403

Lactococcus lactis subsp. lactis. This subspecies is used to make soft cheeses. Lactococcus lactissubsp. lactis Il1403. This strain is used widely in laboratory research and is a plasmid-free derivative of strain IL594 isolated from a cheese starter culture. The genome shows many insertion sequences and prophages, and surprisingly, a large number of genes involved in respiration, suggesting that this organism may aerobically respire.
