From: Garvicin Q: characterization of biosynthesis and mode of action
Mode of action of garvicin Q. A Sensitivity of L. monocytogenes EGDe, L. monocytogenes EGY2, L. innocua LMG2785, L. lactis IL1403 and C. glutamicum ATCC13032 towards purified garvicin Q. B and C Viable cell count (log cfu/ml) of L. lactis IL1403 B and L. innocua LMG2785 C after treatment with garvicin Q (GarQ). As controls, bacteria were treated with nisin (Nis; bacteriolytic), chloramphenicol (Cm; bacteriostatic) or water (H2O; negative control). D Fluorescence intensity ration with emission at 520 nm after excitation at 400 and 480 nm (ratio RFU 400/480) biosensors L. innocua LMG2785/pNZ-pHin2Lm (Lin) and L. lactis IL1403/pNZ-pHin2Lm (Lla) following treatment with a garvicin Q RPC preparation (GarQ), and nisin (6.25 µg/ml; Nis) compared to unreated controls (LMB). All values are mean ± standard deviation of n = 3 independent cultures
