Use of green fluorescent protein to monitor cell envelope stress in Lactococcus lactis.


ABSTRACT: A Lactococcus lactis reporter system suitable to detect cell envelope stress in high-throughput settings was developed by fusing the CesR-regulated promoter of llmg0169 to the gfp(uv) gene. A dot blot assay allowed fast detection of green fluorescent protein (GFP) fluorescence even at low production levels. Unexpectedly, this promoter was also induced by mitomycin C via CesR.
