Fig. 1From: Screening for inhibitors of mutacin synthesis in Streptococcus mutans using fluorescent reporter strainsPopulation wide activation of the mutacin VI promoter of S. mutans UA159 by MIP. Reporter strain S. mutans 423p – gfp + was cultivated in BM medium supplemented with 0.5% glucose and 2.5 μM MIP (for induction of mutacin transcription). After 8 h of growth (37 °C, 5% CO2) cells were observed under the fluorescence microscope. See Methods for further detailsBack to article page
