Abstract
The diversity of ammonia-oxidizing bacteria in aquatic sediments was studie d by retrieving ammonia monooxygenase and methane monooxygenase gene sequen ces. Methanotrophs dominated freshwater sediments, while beta-proteobacteri al ammonia oxidizers dominated marine sediments. These results suggest that gamma-proteobacteria such as Nitrosococcus oceani are minor members of mar ine sediment ammonia-oxidizing communities.
