Cold shock proteins of Lactococcus lactis MG1363 are involved in cryoprotection and in the production of cold-induced proteins

The 7-kDa cold shock proteins of Lactococcus lactis MG1363 not only protect the bacterium from low temperatures but also regulate the production of non-7-kDa cold-induced proteins. Lactic acid bacteria are used in industrial fermentation and they undergo a variety of temperature changes during this process.
