Physiological characterization of an anaerobic ammonium-oxidizing bacterium belonging to the "Candidatus scalindua" group.

چکیده
The phylogenetic affiliation and physiological characteristics (e.g., Ks and maximum specific growth rate [μmax]) 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.

Anaerobic ammonium oxidation (anammox) is both a promising process in wastewater treatment and a long overlooked microbial physiology that can contribute significantly to biological nitrogen cycling in the world's oceans. Anammox is mediated by a monophyletic group of bacteria that branches deeply in the Planctomycetales. Here we describe a new genus and species of anaerobic ammonium oxidizing ...
متن کاملThe metagenome of the marine anammox bacterium ‘Candidatus Scalindua profunda’ illustrates the versatility of this globally important nitrogen cycle bacterium
Anaerobic ammonium-oxidizing (anammox) bacteria are responsible for a significant portion of the loss of fixed nitrogen from the oceans, making them important players in the global nitrogen cycle. To date, marine anammox bacteria found in marine water columns and sediments worldwide belong almost exclusively to the 'Candidatus Scalindua' species, but the molecular basis of their metabolism and ...

Anaerobic ammonium oxidizing (anammox) bacteria are responsible for a significant portion of the loss of fixed nitrogen from the oceans, making them important players in the global nitrogen cycle. To date, marine anammox bacteria found in both water columns and sediments worldwide belong almost exclusively to "Candidatus Scalindua" species. Recently the genome assembly of a marine anammox enric...
متن کاملDraft Genome Sequence of Anammox Bacterium “Candidatus Scalindua brodae,” Obtained Using Differential Coverage Binning of Sequencing Data from Two Reactor Enrichments
We present the draft genome of anammox bacterium "Candidatus Scalindua brodae," which at 282 contigs is a major improvement over the highly fragmented genome assembly of related species "Ca. Scalindua profunda" (1,580 contigs) which was previously published.
متن کاملEnrichment using an up-flow column reactor and community structure of marine anammox bacteria from coastal sediment.
We established an enrichment culture of marine anaerobic ammonium oxidation (anammox) bacteria using an up-flow column reactor fed with artificial sea water supplemented with nitrogen and minerals and inoculated with coastal surface sediment collected from Hiroshima Bay. After 2 months of reactor operation, simultaneous removal of NH(4)(+) and NO(2)(-) was observed, suggesting that an anammox r...
