The class Deltaproteobacteria comprises an ecologically and metabolically diverse group of
bacteria best known for dissimilatory sulphate reduction and predatory behaviour. Although …

High throughput sequencing of phylogenetic and functional gene amplicons provides
tremendous insight into the structure and functional potential of complex microbial communities. …

Sulfur-cycling microorganisms impact organic matter decomposition in wetlands and consequently
greenhouse gas emissions from these globally relevant environments. However, their …

Extracellular DNA is a major macromolecule in global element cycles, and is a particularly
crucial phosphorus, nitrogen and carbon source for microorganisms in the seafloor. …

Microorganisms in marine sediments play major roles in marine biogeochemical cycles by
mineralizing substantial quantities of organic matter from decaying cells. Proteins and lipids …

Genes encoding dissimilatory sulfite reductase ( DsrAB ) are commonly used as diagnostic
markers in ecological studies of sulfite‐ and sulfate‐reducing microorganisms. Here, we …

Recent evidence for intimate relationship of plants with their microbiota shows that plants
host individual and diverse microbial communities that are essential for their survival. …

Seafloor microorganisms impact global carbon cycling by mineralizing vast quantities of
organic matter (OM) from pelagic primary production, which is predicted to increase in the Arctic …

Ammonia-oxidizing archaea (AOA) play an important role in the nitrogen cycle and account
for a considerable fraction of the prokaryotic plankton in the ocean. Most AOA lack the …

Microbial diversity in the environment is mainly concealed within the rare biosphere (all
species with <0.1% relative abundance). While dormancy explains a low-abundance state very …
