Reduction of Ferric Compounds by Soil Bacteria [PDF]
Journal of General Microbiology, 1954 SUMMARY: Reduction of ferric lactate by washed cell suspensions of Bacillus circulans, B. megaterium and Aerobacter aerogenes takes place in the presence of suitable hydrogen donors. Ferric hydroxide is reduced when αα'-dipyridyl is present in the cell + substrate system.

Evaluation of electron-shuttling compounds in microbial ferric iron reduction [PDF]
FEMS Microbiology Letters, 2003 Iron-reducing bacteria can transfer electrons to ferric iron oxides which are barely soluble at neutral pH, and electron-shuttling compounds or chelators are discussed to be involved in this process. Experiments using semipermeable membranes for separation of ferric iron-reducing bacteria from ferric iron oxides do not provide conclusive results in ...
