%X The nitrogen-cycling bacteria in a near-shore marine-cultural sediments were investigated. Results indicated that ammonifying and nitrate-reducing bacteria (NRB) were the most abounding populations. The abundance of nitrate-reducing bacteria occurred in the surface layer of the sediment was higher than that in the bottom layer. 106 bacterial strains were obtained from sediment samples and were tested for their nitrate reducing ability. The results showed that 58 strains of them were able to reduce nitrate. The dominant nitrate-reducing strains were preliminarily identified as Gram positive bacteria and belong to the genus of Bacillus, Halobacillus, Brevibacillus, Planococcus and Planomicrobium.The richness of diversity of nitrate-reducing bacteria was further revealed by the analysis of the sequences of their 16S rRNA genes.
