FIG. 3.

Growth of wild-type C. jejuni strains in defined medium supplemented with different carbon sources. (A) Basal medium was supplemented with d-glucose (50 mM), l-fucose (50 mM), sodium pyruvate (20 mM), or a combination of l-aspartate, l-glutamate, l-proline, and l-serine (DEPS; 390 mM, 360 mM, 560 mM, and 1.3 mM, respectively). White columns, NCTC 11168; gray columns, 81116; black columns, 81-176. Bars represent the mean viable cell counts ± standard errors from three separate experiments. (B) Passage of wild-type NCTC 11168 in defined medium containing l-fucose (50 mM). Points represent mean viable cell counts ± standard errors from three separate experiments. Arrows indicate passage after 24 h of growth to fresh medium at a 1:100 dilution.
