Refinement of the “ Candidatus Accumulibacter” genus based on metagenomic analysis of biological nutrient removal (BNR) pilot-scale plants operated with reduced aeration

Citation
Stewart et al. (2024). mSystems 9 (3)
Names
“Accumulibacter”
Abstract
ABSTRACT Members of the “ Candidatus Accumulibacter” genus are widely studied as key polyphosphate-accumulating organisms (PAOs) in biological nutrient removal (BNR) facilities performing enhanced biological phosphorus removal (EBPR). This diverse lineage includes 18 “ Ca . Accumulibacter” species, which have been proposed based on the phylogenetic divergence of the polyphosphate kinase 1 (

Refinement of the “CandidatusAccumulibacter” Genus Based on a Metagenomic Analysis of Biological Nutrient Removal (BNR) Pilot-Scale Plants Operated with Reduced Aeration

Abstract
ABSTRACTMembers of the “CandidatusAccumulibacter” genus are widely studied as key polyphosphate-accumulating organisms (PAOs) in biological nutrient removal (BNR) facilities performing enhanced biological phosphorus removal (EBPR). This diverse lineage includes 18 “Ca. Accumulibacter” species, which have been proposed based on the phylogenetic divergence of the polyphosphate kinase 1 (ppk1) gene and genome-scale comparisons of metagenome-assembled genomes (MAGs).

Medium-Chain Fatty Acid Synthesis by “ Candidatus Weimeria bifida” gen. nov., sp. nov., and “ Candidatus Pseudoramibacter fermentans” sp. nov

Abstract
Chain elongation by medium-chain fatty acid (MCFA)-producing microbiomes offers an opportunity to produce valuable chemicals from organic streams that would otherwise be considered waste. However, the physiology and energetics of chain elongation are only beginning to be studied, and many of these organisms remain uncultured. We analyzed MCFA production by two uncultured organisms that were identified as the main MCFA producers in a microbial community enriched from an anaerobic digester; this c

Autotrophic and mixotrophic metabolism of an anammox bacterium revealed by in vivo13C and 2H metabolic network mapping

Abstract
AbstractAnaerobic ammonium-oxidizing (anammox) bacteria mediate a key step in the biogeochemical nitrogen cycle and have been applied worldwide for the energy-efficient removal of nitrogen from wastewater. However, outside their core energy metabolism, little is known about the metabolic networks driving anammox bacterial anabolism and mixotrophy beyond genome-based predictions. Here, we experimentally resolved the central carbon metabolism of the anammox bacterium Candidatus ‘Kuenenia stuttgart

Abstract
ABSTRACTChain elongation is emerging as a bioprocess to produce valuable medium-chain fatty acids (MCFA; 6 to 8 carbons in length) from organic waste streams by harnessing the metabolism of anaerobic microbiomes. Although our understanding of chain elongation physiology is still evolving, the reverse β-oxidation pathway has been identified as a key metabolic function to elongate the intermediate products of fermentation to MCFA. Here, we describe two chain-elongating microorganisms that were enr

Integrated Omic Analyses Provide Evidence that a “ Candidatus Accumulibacter phosphatis” Strain Performs Denitrification under Microaerobic Conditions

“Accumulibacter phosphatis”
Abstract
“ Candidatus Accumulibacter phosphatis” is widely found in full-scale wastewater treatment plants, where it has been identified as the key organism for biological removal of phosphorus. Since aeration can account for 50% of the energy use during wastewater treatment, microaerobic conditions for wastewater treatment have emerged as a cost-effective alternative to conventional biological nutrient removal processes. Our report provides strong genomics-based evid

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “ Candidatus Nitrospira nitrosa”

Abstract
Nitrospira -like bacteria are among the most diverse and widespread nitrifiers in natural ecosystems and the dominant nitrite oxidizers in wastewater treatment plants (WWTPs). The recent discovery of comammox-like Nitrospira strains, capable of complete oxidation of ammonia to nitrate, raises new questions about specific traits responsible for the functional versatility and adaptation of this genus to a variety of environments.
