DosD positively regulates aerobic biofilm production in S. putrefaciens CN32.

(A) Schematic of the genetic arrangement of DosD and its domain architecture. (B) Aerobic biofilm mass profiles of WT (white columns) and ΔdosD (gray columns) with simultaneous determination of growth of WT (solid line) and ΔdosD (dashed line). (C) Biofilm formation by ΔdosD complemented by vector-bearing dosD driven by its native promoter. The empty vector was transformed into WT and ΔdosD mutants as a control. (D) Attachment abilities of WT and ΔdosD. The average number of cells attached to the cover slips was counted in randomly picked areas of ten microscopic images. Each experiment was repeated at least three times and representative results are provided. Error bars refer to the standard deviation of the three samples.
