From: Role of the small RNA RyhB in the Fur regulon in mediating the capsular polysaccharide biosynthesis and iron acquisition systems in Klebsiella pneumoniae

Figure 5

Deletion of ryhB decreases K. pneumoniae Δ fur siderophore production assessed using CAS assay. Each of the strains, Δfur and Δfur ΔryhB, was grown overnight in LB medium or M9 minimal medium, and then 5 μl each of cultures respectively was added onto a CAS agar plate. The orange halos formed around the colonies correspond to the iron-chelating activity of the siderophores in bacteria.
