"Candidatus Scalindua" is a bacterial genus, and a proposed member of the order Planctomycetes. These bacteria lack peptidoglycan in their cell wall and have a compartmentalized cytoplasm. They are ammonium oxidizing bacteria found in marine environments.
"Candidatus Scalindua" is a bacterial genus, member of the order Planctomycetes. These bacteria lack peptidoglycan in their cell wall and have a compartmentalized cytoplasm.Candidatus Scalindua spp. can be further divided into three species: Scalindua brodae, Scalindua wagneri, and Scalindua sorokinii. They are ammonium oxidising bacteria found in marine environments. The genus Ca. Scalindua are the most abundant annamox bacteria in marine environments, so they are vital to the Earth's nitrogen cycle.
Members of the proposed genus Scalindua are anaerobic anammox (ammonium oxidizing) bacteria. The ammonium-oxidizing reaction composes a significant part of the global nitrogen cycle; by some estimates it is the cause of up to 50% of total nitrogen turnover in marine environments. It consists of the oxidization of ammonium using nitrite as an electron acceptor (both are fixed nitrogen) and subsequent generation of nitrogen gas:
“NH4+ + NO2− = N2 + 2H2O (ΔG° = -357 kj mol-1)”
