Abstract
Background and Objective: At the Musi River, activities such as industries, agriculture, plantation, coal stockpile, harbour and water transportation could probably contribute to the waste inputs containing some chemical components and eutrophication which have negative ecological impact on the aquatic organisms including bacteria. Materials and Methods: In the present study we analysed the abundance and community of Ammonia-Oxidizing Bacteria (AOB), during rainy and dry seasons in Musi River based on PCR T-RFLP analysis of 16S rRNA gene and amoA gene that were digested with AluI, BsuRI, and MspI. Results: Nitrosospira and Nitrosomonas were dominant of 16S rRNA gene and amoA gene in all sampling sites, but Nitrosococcus was clearly found only in brackish water sites. AOB communities of 16S rRNA gene and amoA gene in dry season were higher than in rainy season. The salinity, temperature, DO and nutrients contributed on the AOB community. But salinity significantly affected on the AOB community. Conclusion: Variability in salinity caused the spatial distribution of the AOB in the Musi River.
