Abstract excerpt
Azotobacter vinelandii cydAB mutants lacking cytochrome bd lost viability in stationary phase, irrespective of temperature, but microaerobiosis or iron addition to stationary phase cultures prevented viability loss. Growth on solid medium was inhibited by a diffusible factor from neighbouring cells, and by iron chelators, In(III) or Ga(III); microaerobic growth overcame inhibition by the extracellular factor....
