Isolation and Characterization of a Mesophilic Bacterium Capable of Chemolithotrophic Growth on Ferric Iron Using PCR Amplified Gene Coding for 16S rDNA in Iron Mine Overburden Spoil.

摘要

ABSTRACT Iron (trace element) plays an important role in bacterial metabolism and biogeochemical redox reactions in an ecosystem. Iron mining disrupts ecosystem stability and function due to the mine overburden spoil. Being deficient in nutrients and pyrite (FeS2) contamination, the iron mine spoil harbors specific groups of microbial community (chemolithotrophs), which reduced Fe(III) that act as an electron sink to Fe(II) specifically by the iron reducing bacteria. Besides, microbial reductio.
