Microbial ferric iron reduction, with organic carbon or hydrogen as the electron donor, is one of the most important biogeochemical processes in anoxic paddy soils; however, the diversity and community structure of hydrogen-dependent dissimilatory iron-reducers remain unknown. Potential H2-dependent Fe（III）-reducing bacteria in paddy soils were explored using enrichment cultures with ferrihydrite or goethite as the electron acceptor and hydrogen as the electron donor. Terminal restriction fragment length polymorphism （T-RFLP） analysis and cloning/sequencing were conducted to reveal bacterial community structure. Results showed that Geobacter and Clost^dium were the dominant bacteria in the enrichment cultures. Fe（III） oxide mineral phases showed a strong effect on the community structure; Geobaeter and Clostridium were dominant in the ferrihydrite treatment, while Glostridium spp. were dominant in the goethite treatment. These suggested that H2-dependent Fe（liI）-redueing bacteria might be widely distributed in paddy soils and that besides Geobacter, Clostmdium spp. might also be an important group of H2-dependent Fe（III）-reducing microorganisms.
