FIG 2.

Influence of chpT and ctrA on the swimming behavior of AM1 cells. The swimming ability of chpT and ctrA mutant strains was tested. (A) Swimming of BV3 (AM1 ΔfleQ::Kan^r ΔchpT::Ω^Spc) strain, and complementation with plasmid pRK_chpT. (B) Swimming of EA1 (AM1 ΔfleQ::Kan^r ΔctrA::aadA) and complementation with the plasmid pRK_ctrA. Plates were prepared with Sistrom's minimal medium containing 15 mM succinic acid and 0.22% agar. After inoculation the plates were incubated anaerobically under continuous illumination for 60 h.
