Oceans are regarded as a plentiful and sustainable source of biological compounds.
Enzymes are a group of marine biomaterials that have recently drawn more attention …

Extracellular enzymes produced by heterotrophic microbial communities are major drivers of
carbon and nutrient cycling in terrestrial, freshwater, and marine environments. Although …

Heterotrophic microbial communities play a central role in the marine carbon cycle. They are
active in nearly all known environments, from the surface to the deep ocean, in the …

Arctic marine microbes are affected by environmental changes that may ultimately influence
their functions in carbon cycling. Here, we investigated in concert the structure and …

Aquatic sediments harbour diverse microbial communities that mediate organic matter
degradation and influence biogeochemical cycles. The pool of bioavailable carbon …

Heterotrophic microbes initiate the degradation of high molecular weight organic matter
using extracellular enzymes. Our understanding of differences in microbial enzymatic …

Increasing glacial discharge can lower salinity and alter organic matter (OM) supply in fjords,
but assessing the biogeochemical effects of enhanced freshwater fluxes requires …

The identities and biochemical properties of extracellular enzymes present in natural
environments are poorly constrained. We used a series of competitive inhibition experiments …

The “priming effect,” in which addition of labile substances changes the remineralization rate
of recalcitrant organic matter, has been intensively studied in soils, but is less well …

Marine microorganisms and their extracellular enzymes (ECEs) play an important role in the
remineralization of organic material by hydrolyzing high-molecular-weight substrates to …
