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

Article Abstract:

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.

Analysis of the role of 7 kDa cold-shock proteins of Lactococcus lactis MG1363 in cryoprotection

Article Abstract:

Research was conducted to examine the effect of low temperature treatment on the survival of the lactococcus bacterial species after freezing (cryoprotection). Results show that cells shocked to 10 degrees C for 4 h exhibit 7 kD cold-induced proteins which confer a 100-fold cryoprotection.
