| Abstract: | Background aim and scope Though the tidal Anacostia River, a highly polluted riverine system, has been well characterized with regard to contaminants,
its overall resident bacterial populations have remained largely unknown. Improving the health of this system will rely upon
enhanced understanding of the diversity and functions of these communities. Bacterial DNA was extracted from archived (AR,
year 2000) and fresh sediments (RE, year 2006) collected from various locations within the Anacostia River. Using a combination
of metabolic and molecular techniques, community snapshots of sediment bacterial diversity and activity were produced. |
