  • a Biolog Phenotype MicroArray comparisons were identified using the opm package (63 [see Materials and Methods]) for WT CL150 compared to the all-ECF σ deletion strain RFF625c.

  • b Shown are the plate number and then well number of Biolog Phenotype MicroArray 96-well plates. PM2, carbon sources; PM4, phosphorous and sulfur sources; PM9, osmolytes; PM11 to -20, chemical sensitivity tests for bacteria.

  • c For chemical stress tests, the number indicates which of the four concentrations (where 1 is lowest and 4 is highest) had a significant effect.

  • d AUC, area under the concentration-time curve (see Materials and Methods).

  • e Compounds listed as "antibacterial" possess antibacterial activity; however, their primary commercial use may not be treatment of bacterial infections (examples include tolylfluanid, tinidazole, and bleomycin).
