DGGE profile of the enrichment culture grown in media containing various concentrations of 4-aminopyridine. The enrichment culture was used to inoculate basal medium without 4-aminopyridine (lane 1) and with 4-aminopyridine (lane 2, 2.13 mM; lane 3, 10.6 mM; and lane 4, 53.2 mM), and the subcultures were incubated at 30°C with shaking. After 4 days of cultivation, the subcultures were sampled for PCR-DGGE analysis. The standard amplified fragments from strains 4AP-A, 4AP-B, 4AP-C, 4AP-D, 4AP-E, 4AP-F, and 4AP-G were loaded in lane M.
