Abundance and population structure of ammonia-oxidizing bacteria that inhabit canal sediments receiving effluents from municipal wastewater treatment plants.

A polyphasic, culture-independent study was conducted to investigate the abundance and population structure of ammonia-oxidizing bacteria (AOB) in canal sediments receiving wastewater discharge. The abundance of AOB ranged from 0.2 to 1.

Characterization and quantification of ammonia-oxidizing bacteria in eutrophic coastal marine sediments using polyphasic molecular approaches and immunofluorescence staining.

Tokyo Bay, a eutrophic bay in Japan, receives nutrients from wastewater plants and other urban diffuse sources via river input. A transect was conducted along a line from the Arakawa River into Tokyo Bay to investigate the ecological relationship between the river outflow and the distribution, abundance and population structure of ammonia-oxidizing bacteria (AOB). Five surficial marine sediments were collected and analysed with polyphasic approaches.
