Trans complementation of the sorbitol utilization regulatory machinery in L. plantarum 90. Bacteria carrying (A,E,F) pRCR16 (,
), (B,E,F) pRCR17 (
,
), (C,E,F) pRCR18 (
,
) or (D,E,F) pRCR19 (
,
) were grown in MRSG and at time 0 were transferred to fresh MRSS (open symbols) or to MRSG (closed symbols). OD600nm and fluorescence of the cultures were monitored every hour. Overlays of images of the cultures taken at time 0 and after 2, 4, and 6 h incubation by phase contrast and fluorescent microscopy are depicted. The experiments were performed in triplicate and the mean value and standard deviation is depicted.
