Abstract

Bioreduction of ferric iron in anoxic conditions with respect to biological and environmental aspects is an important process. This process is considered in PADDY SOILS and mostly controlled by microbial activities. Ferric iron is one of the most terminal electron acceptor in these soils. Present study with the aim of isolation and identification of some bacteria with high ability in ferric iron reduction in PADDY SOILS of northern Iran was conducted. Testing of ability of isolated ferric iron reducing bacteria was conducted in nutrient broth according to biogenic Fe (II) produced and the results was compared with Shewanella sp that showed the highest concentration of ferrous iron. Then three superior bacteria were chosen and genomic DNA of these bacteria tested by using of PCR and fd1 and rd1 primers for 16S rRNA amplification sequence analysis. By using the BLAST program of these isolates and isolates in data bases, all selective isolates were belonged to Bacillus sp. Sequence of PS11 isolate showed 99.4% of homology with Geobacillus stearothermophilus and PS23 showed 98.4% homology with PS23 and B. subtilis.Sequence of PS23 also showed 98% homology with B. subtilis and B. thuringiensis that these isolates have ability to reduce ferric to ferrous iron in vitro conditions.
