Insights into the Role of Sulfate-reducing Bacteria in Iron (III) Reduction from Transcriptome Analysis

We established three sulfate-reducing bacteria (SRB) enrichment cultures from different paddy soils and compared their metabolism characters under sulfa-containing and sulfate-free conditions using transcriptome analysis. In this manuscript we attempted to assess the function of DsrAB and DsrC during sulfate reducing process in SRB community level and study the metabolism of SRB enrichment cultures influenced by sulfate. We also investigated the corresponding differences in sulfates between different SRB community structures.
