Genome-resolved metagenomics reveals site-specific diversity of episymbiotic CPR bacteria and DPANN archaea in groundwater ecosystems

Nature Microbiology, Journal Year: 2021, Volume and Issue: 6(3), P. 354 - 365

Published: Jan. 25, 2021

Abstract Candidate phyla radiation (CPR) bacteria and DPANN archaea are unisolated, small-celled symbionts that often detected in groundwater. The effects of groundwater geochemistry on the abundance, distribution, taxonomic diversity host association CPR has not been studied. Here, we performed genome-resolved metagenomic analysis one agricultural seven pristine microbial communities recovered 746 genomes total. sites, which serve as local sources drinking water, contained up to 31% 4% archaea. We observed little species-level overlap metagenome-assembled (MAGs) across indicating may be differentiated according physicochemical conditions populations. Cryogenic transmission electron microscopy imaging genomic analyses enabled us identify lineages reproducibly attach cells showed growth seems stimulated by attachment host-cell surfaces. Our reveals site-specific coexist with diverse hosts aquifers. Given organisms have identified human microbiomes their presence is correlated diseases such periodontitis, our findings relevant considerations water quality health.

Multiple energy sources and metabolic strategies sustain microbial diversity in Antarctic desert soils

Proceedings of the National Academy of Sciences, Journal Year: 2021, Volume and Issue: 118(45)

Published: Nov. 3, 2021

Significance Diverse microbial life has been detected in the cold desert soils of Antarctica once thought to be barren. Here, we provide metagenomic, biogeochemical, and culture-based evidence that Antarctic soil microorganisms are phylogenetically functionally distinct from those other adopt various metabolic ecological strategies. The most abundant community members metabolically versatile aerobes use ubiquitous atmospheric trace gases potentially meet energy, carbon, and, through water production, hydration needs. Lineages capable harvesting solar oxidizing edaphic inorganic substrates, or adopting symbiotic lifestyles were also identified. Altogether, these findings insights into adaptation extreme energy limitation will inform ongoing efforts conserve unique biodiversity on this continent.

Halophiles and Their Biomolecules: Recent Advances and Future Applications in Biomedicine

Marine Drugs, Journal Year: 2019, Volume and Issue: 18(1), P. 33 - 33

Published: Dec. 30, 2019

The organisms thriving under extreme conditions better than any other organism living on Earth, fascinate by their hostile growing parameters, physiological features, and production of valuable bioactive metabolites. This is the case microorganisms (bacteria, archaea, fungi) that grow optimally at high salinities are able to produce biomolecules pharmaceutical interest for therapeutic applications. As along as microbiota being approached massive sequencing, novel insights revealing environmental which compounds produced in microbial community without more stress sharing same substratum with peers, salt. In this review reported molecules described halophilic a spectrum action vitro: antimicrobial anticancer. mechanisms these molecules, urgent need introduce alternative lead current aspects exploitation its limitations discussed.

Undinarchaeota illuminate DPANN phylogeny and the impact of gene transfer on archaeal evolution

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Aug. 7, 2020

Abstract The recently discovered DPANN archaea are a potentially deep-branching, monophyletic radiation of organisms with small cells and genomes. However, the monophyly early emergence various clades their role in life’s evolution debated. Here, we reconstructed analysed genomes an uncharacterized archaeal phylum ( Candidatus Undinarchaeota), revealing that its members have and, while being able to conserve energy through fermentation, likely depend on partner for acquisition certain metabolites. Our phylogenomic analyses robustly place Undinarchaeota as independent lineage between two highly supported ‘DPANN’ clans. Further, our suggest exchanged core genes hosts, adding difficulty placing tree life. This pattern can be sufficiently dominant allow identifying known symbiont-host based routes gene transfer. Together, work provides insights into origins hosts.

Ancestral Absence of Electron Transport Chains in Patescibacteria and DPANN

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: Aug. 17, 2020

Recent discoveries suggest that the candidate superphyla Patescibacteria and DPANN constitute a large fraction of phylogenetic diversity Bacteria Archaea. Their small genomes limited coding potential have been hypothesized to be ancestral adaptations obligate symbiotic lifestyles. To test this hypothesis, we performed cell-cell association, genomic, analyses on 4,829 individual cells Archaea from 46 globally distributed surface subsurface field samples. This confirmed ubiquity abundance in environments, size their cells, divergence gene content other Our most studied environments do not form specific physical associations with microorganisms. These data also unusual genomic features prevalent auxotrophies may result ancestral, minimal cellular energy transduction mechanisms lack respiration, thus relying solely fermentation for conservation.

Microbiome of the deep Lake Baikal, a unique oxic bathypelagic habitat

Limnology and Oceanography, Journal Year: 2019, Volume and Issue: 65(7), P. 1471 - 1488

Published: Dec. 30, 2019

Abstract Lake Baikal is the deepest lake in world. Its depth provides only bathypelagic (> 1000 m deep) freshwater habitat on Earth and its oxic, ultra‐oligotrophic features make it a counterpart of deep ocean. Here we have analyzed metagenomes from 1250 1350 samples built 231 metagenome‐assembled genomes (MAGs). We detected high fractions Thaumarchaeota (ca. 20% 16S rRNA reads) members candidate phyla radiation (CPR) (3–4.5%). Among MAGs, obtained ammonia‐oxidizing archaea (AOA, Nitrosopumilaceae) bacteria (AOB, Nitrosomonadaceae), nitrite‐oxidizers (Nitrospirae) indicating very active nitrification. A new clade SAR202 Chloroflexi methanotrophs ( Methyloglobulus ) were also remarkably abundant, latter reflecting possible role methane oxidation as well. Novel species streamlined cosmopolitan such Ca. Fonsibacter or acI Actinobacteria more abundant at surface but present waters. Conversely, CPRs, Myxococcales, Chloroflexi, DPANN (Diapherotrites, Parvarchaeota, Aenigmarchaeota, Nanoarchaeota Nanohaloarchaeota) archaea, Gammaproteobacteria found samples. noted various important taxonomic metabolic differences between aphotic region marine waters similar depth: Betaproteobacteriales, CPR, superphylum Baikal, while Deltaproteobacteria, Gammaproteobacteria, Alphaproteobacteria prevailed oceanic The genes mediating ammonia oxidation, aromatic compound degradation, alkane/methanesulfonate monooxygenases higher numbers compared to their counterparts own surface. Overall, seems be less relevant than salinity configuring microbial community.
