Fluorescent method for monitoring cheese starter permeabilization and lysis
Article Abstract:
Research has been conducted on the lysis of the cheese starter bacteria. The fluorescence method of monitoring this lysis via dual staining with the LIVE/DEAD BacLight bacterial visibility kit is described.

Glutathione protects Lactococcus lactis against oxidative stress
Article Abstract:
Research demonstrates that Lactococcus lactis subsp. cremoris strain SK11 in their stationary phase exhibit about five-fold increased resistance to hydrogen peroxide stress in the presence of glutathione. Data indicate that glutathione mediated resistance may be due to the activation of glutathione-glutathione peroxidase-glutathione reductase system.

Lysis of Lactococcus lactis subsp. cremoris SK110 and its nisin-immune transconjugant in relation to flavor development in cheese
Article Abstract:
Transposon Tn5276-NI was conjugated with the Lactococcus lactis subsp. cremoris SK110 strain to create a nisin-producing cheese starter. The transconjugant strain was found to induce a more bitter flavor in cheese. An analysis of the sensitivity of induced lysis under various growth conditions revealed differences in the sensitivity of strain SK110 cells and transconjugant SK110::Tn5276-NI cells to temperature-induced lysis. A difference was also observed in the peptidoglycan compositions of the transconjugant and strain SK110.
