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 (

Abstract
ABSTRACT Filamentous Chloroflexota are abundant in activated sludge wastewater treatment plants (WWTPs) worldwide and are occasionally associated with poor solid-liquid separation or foaming, but most of the abundant lineages remain undescribed. Here, we present a comprehensive overview of Chloroflexota abundant in WWTPs worldwide, using high-quality metagenome-assembled genomes (MAGs) and 16S rRNA amplicon data from 740 Danish and global WWTPs. Many novel taxa were descri

Abstract
ABSTRACT The phylum Gemmatimonadota comprises mainly uncultured microorganisms that inhabit different environments such as soils, freshwater lakes, marine sediments, sponges, or corals. Based on 16S rRNA gene studies, the group PAUC43f is one of the most frequently retrieved Gemmatimonadota in marine samples. However, its physiology and ecological roles are completely unknown since, to date, not a single PAUC43f isolate or me

Metagenomic Discovery of “ Candidatus Parvarchaeales”-Related Lineages Sheds Light on Adaptation and Diversification from Neutral-Thermal to Acidic-Mesothermal Environments

Abstract
“ Candidatus Parvarchaeales” microbes may represent a lineage uniquely distributed in extreme environments such as AMD and hot springs. However, little is known about the strategies and processes of how they adapted to these extreme environments.

Comparative Genomic Insights into the Evolution of Halobacteria -Associated “ Candidatus Nanohaloarchaeota”

Citation
Zhao et al. (2022). mSystems 7 (6)
Names
Ca. Nanohaloarchaeota
Abstract
The DPANN superphylum is a group of archaea widely distributed in various habitats. They generally have small cells and have a symbiotic lifestyle with other archaea.

Reevaluation of the Phylogenetic Diversity and Global Distribution of the Genus “CandidatusAccumulibacter”

Abstract
“CandidatusAccumulibacter” is the most studied PAO, with a primary role in biological nutrient removal. However, the species-level taxonomy of this lineage is convoluted due to the use of different phylogenetic markers or genome sequencing approaches. Here, we redefined the phylogeny of these organisms, proposing a comprehensive approach which could be used to address the classification of other diverse and uncultivated lineages.

Deciphering Symbiotic Interactions of “ Candidatus Aenigmarchaeota” with Inferred Horizontal Gene Transfers and Co-occurrence Networks

Abstract
Recent advances in sequencing technology promoted the blowout discovery of super tiny microbes in the Diapherotrites , Parvarchaeota , Aenigmarchaeota , Nanoarchaeota , and Nanohaloarchaeota (DPANN) superphylum. However, the unculturable properties of the majority of microbes impeded our investigation of their behavior and symbiotic lifestyle in the corresponding c

Production and Excretion of Polyamines To Tolerate High Ammonia, a Case Study on Soil Ammonia-Oxidizing Archaeon “ Candidatus Nitrosocosmicus agrestis”

Citation
Liu et al. (2021). mSystems 6 (1)
Names
Ca. Nitrosocosmicus Ca. Nitrosocosmicus agrestis
Abstract
Ammonia tolerance of AOA is usually much lower than that of the AOB, which makes the AOB rather than AOA a predominant ammonia oxidizer in agricultural soils, contributing to global N 2 O emission. Recently, some AOA species from the genus “ Ca. Nitrosocosmicus” were also found to have high ammonia tolerance.
