Response to cystine / cysteine in aerobic versus anaerobic conditions in long-time motility-plate assays. (A) Bacteria were inoculated in the center of minimal media plates. Growth conditions were as described in Fig. 1C. See Experimental Procedures for description of the anaerobic chamber. (B) Chemical-in-plug assay. The hard-agar plugs on the right contain the test chemical, which diffuses into the soft-agar media (see Experimental Procedures). Bacteria were inoculated at some distance and plates incubated for 22 h at 37°C. BC only* (JW20).
