Swarming assay and tumbling bias of B. pseudofirmus OF4 strains

Strain	Colony diameter (mm)^a	Tumbling^b
811M (wild-type)	17.5 ± 2.0	±
SC34 (ΔncbA)	11.8 ± 1.0	++
SC34 / pSC-CFP	15.8 ± 1.9	±
SC34 / pCFP	12.0 ± 0.5	++
SC34-R (ΔncbA, ncbA restored)	17.0 ± 1.8	+

^a)

Measured after 10 hr on MYE medium, pH 10, solidified with 0.3% agar. Mean values of three independent experiments with standard deviations of the mean.

^b)
