Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested have a central part global biogeochemical nitrogen cycle since oxygenation Earth. The cultivation several ammonia-oxidizing archaea (AOA) as well discovery that archaeal monooxygenase (amo)-like gene sequences are nearly ubiquitously distributed in environment and outnumber their bacterial counterparts many habitats fundamentally revised our understanding nitrification. Surprising insights into physiological distinctiveness AOA mirrored by recognition phylogenetic uniqueness these microbes, which fall within novel phylum now known Thaumarchaeota. relative importance nitrification, compared bacteria (AOB), is still under debate. This minireview provides synopsis current knowledge diversity physiology AOA, factors controlling ecology, role carbon cycling potential involvement production greenhouse gas nitrous oxide. It emphasizes activity-based analyses studies formulates priorities for future research.

Methane yield phenotypes linked to differential gene expression in the sheep rumen microbiome

Ruminant livestock represent the single largest anthropogenic source of potent greenhouse gas methane, which is generated by methanogenic archaea residing in ruminant digestive tracts. While differences between individual animals same breed amount methane produced have been observed, basis for this variation remains to be elucidated. To explore mechanistic production, we measured yields from 22 sheep, revealed that are a reproducible, quantitative trait. Deep metagenomic and metatranscriptomic sequencing demonstrated similar abundance methanogens methanogenesis pathway genes high low emitters. However, transcription was substantially increased sheep with yields. These results identify discrete set rumen whose profiles correlate provide new targets CH 4 mitigation at levels microbiota composition transcriptional regulation.

A critical review of mineral–microbe interaction and co-evolution: mechanisms and applications

National Science Review, Год журнала: 2022, Номер 9(10)

Опубликована: Июль 4, 2022

Mineral–microbe interactions play important roles in environmental change, biogeochemical cycling of elements and formation ore deposits. Minerals provide both beneficial (physical chemical protection, nutrients, energy) detrimental (toxic substances oxidative pressure) effects to microbes, resulting mineral-specific microbial colonization. Microbes impact dissolution, transformation precipitation minerals through their activity, either genetically controlled or metabolism-induced biomineralization. Through these interactions, microbes co-evolve Earth history. typically occur at microscopic scale but the effect is often manifested global scale. Despite advances achieved decades research, major questions remain. Four areas are identified for future research: integrating mineral ecology, establishing biosignatures, linking laboratory mechanistic investigation field observation, manipulating mineral–microbe benefit humankind.

Aerobic gammaproteobacterial methanotrophs mitigate methane emissions from oxic and anoxic lake waters

Limnology and Oceanography, Год журнала: 2016, Номер 61(S1)

Abstract Freshwater lakes represent a substantial natural source of methane to the atmosphere and thus contribute global climate change. Microbial oxidation is an important control on release from these systems, where oxygen appears be most essential electron acceptor for this process. However, there extensive geochemical evidence that also oxidized under anoxic conditions in lakes, though details about exact mechanism have still not been resolved. Here, we investigated fate water column meromictic Lake Zug. We provide ongoing at oxic/anoxic boundary hypolimnion, both apparently mediated by aerobic methane‐oxidizing bacteria. Gammaproteobacterial methanotrophs (gamma‐MOB) dominated indigenous methanotrophic community were active all conditions—oxic, sub‐oxic anoxic. Methane was stimulated additions or iron manganese oxides conditions. In latter case, trace amounts may required activation, yet findings indicate gamma‐MOB Zug might able respire acceptors other than oxygen. propose are actively removing lake waters, contributing mitigation habitats.
