Article Title: The Extracytoplasmic Function Sigma Factor SigV Plays a Key Role in the Original Model of Lysozyme Resistance and Virulence of Enterococcus faecalis
doi: 10.1371/journal.pone.0009658
Figure Lengend Snippet: The parental strain E. faecalis JH2-2 ( 1 ), and its derivative mutants Δ sigV ( 2 ), SAS pMSP3535 ( 3 ), and SAS pMSP3535- sigV ( 4 ) were grown on LB solid medium without lysozyme ( A ) or supplemented with 20 mg/ml of lysozyme ( B ). Five µl of 10 −2 dilution of overnight cultures adjusted to OD 600 = 1 in physiological water were plated on solid medium, incubated at 37°C for 48 hours and photographed.
Article Snippet: For this purpose, SigV was overproduced using SAS pMSP3535 -sigV and SAS pMSP3535 (control) strains under appropriate condition of nisin (0.5 µg/ml) induction and we analyzed the transcription of these genes using RT-qPCR.
