✦ Synopsis
The ability to reduce ferric iron to the soluble ferrous state has been observed recently among a great number of bacteria, belonging to the Enterobacteriaceae, Bacillaceae and Pseudornonadaceae (OTTOW 1969, 19 70). Even among certain fungi the iron-reducing property was detected (OTTOW and VON KLOPOTEK 1969). The physiological role of ferric iron or the mechanism of iron-reduction still remains unexplained, although the enzyme nitrate reductase seems t o participate as an electron donor (OTTOW 1968, OTTOW and VON KLOPOTEK 1969). Among various enterobacteria and bacilli, two types of nitrate reductase Aand B occur that differ, among other properties, in their action towards chlorate
