ABSTRACT

The phylogenetic affiliation and physiological characteristics (e.g.,

K s

and maximum specific growth rate [μ max ]) of an anaerobic ammonium oxidation (anammox) bacterium, “ Candidatus Scalindua sp.,” enriched from the marine sediment of Hiroshima Bay, Japan, were investigated. “ Candidatus Scalindua sp.” exhibits higher affinity for nitrite and a lower growth rate and yield than the known anammox species.
