FIG 1.

Growth inhibition of B. subtilis ATCC 6633 and B. halodurans C-125 by sublancin 168. (a) Time-dependent changes in OD₆₀₀ of cultures of B. subtilis ATCC 6633 in the absence (circles) or presence of sublancin 168 at 1× MIC (squares) and 4× MIC (triangles). (b) Aliquots of the cultures in panel a were analyzed for CFU. (c) Time-dependent changes in OD₆₀₀ of cultures of B. halodurans C-125. The same symbols are used as in panel a. (d) Aliquots of the cultures in panel c were analyzed for CFU. The mean values of the data from one experiment conducted in triplicate are shown. The data are representative of the results from three independent experiments. The error bars indicate standard deviations. When error bars are not visible, they are smaller than the size of the symbol used.
