Description and Significance
Nitrosarchaeum limnium (formerly Nitrosoarchaeum limnia) is a member of the low-salinity ammonia-oxidizing archaea (AOA), first enriched from sediments in north San Francisco Bay estuary, CA, USA (Blainey et al., 2011; Mosier et al., 2012).
As a member of the ammonia-oxidizing archaea (AOA), N. limnium grows using energy obtained from the oxidation of ammonia (NH4+) to nitrite (NO2-), the first step in nitrification. This process is a critical step in the global nitrogen cycle, as buildup of ammonia in environments can lead to eutrophication and other consequences.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Environment
Habitat; symbiosis; biogeochemical significance; contributions to environment.
