Heterogeneity in respiratory electron transfer and adaptive iron utilization in a bacterial biofilm

Biofilm formation in Bacillus subtilis requires high levels of ferric iron. Here, Qin et al. show that iron accumulation requires production of dihydroxybenzoate (a precursor in siderophore biosynthesis), and matrix-associated iron may be acting as extracellular electron acceptor during respiratory...
