Outline of Final Research Achievements

Arsenic is a pollutant causing serious public health problem, and anaerobic arsenite-oxidizing bacteria are thought to have a great influence on dynamics of arsenic in environment. In this study, new methods to analyze distribution and diversity of anaerobic arsenite-oxidizing bacteria in environments were developed and applied. The obtained results suggested that arsenite-oxidizing bacteria in environments are more diverse than previously thought.
