a
The gene or designation before the slash indicates the genetic background; the gene after the slash indicates the plasmid-borne, autonomously expressed marker.
b
Percentage of wild-type swarm diameter on 0.3% Bromfield agar after 36 h at 30°C. Values are the means of results from four replicates.
