Lytic polysaccharide monooxygenases (LPMOs) facilitate cellulose nanofibrils production

Biotechnology for Biofuels, 2019
Background Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that cleave polysaccharides through an oxidative mechanism. These enzymes are major contributors to the recycling of carbon in nature and are currently used in the ...

Population structure of graptolite assemblages [PDF]

, 1998
Graptolite rhabdosomes display a diverse suite of morphologies. The range of morphotypes present within most moderate to high diversity assemblages from the Ordovician and Silurian is similar, despite the different taxonomic composition of the faunas at ...

Hominid butchers and biting crocodiles in the African Plio-Pleistocene. [PDF]

, 2017
Zooarchaeologists have long relied on linear traces and pits found on the surfaces of ancient bones to infer ancient hominid behaviors such as slicing, chopping, and percussive actions during butchery of mammal carcasses.

Spatial Variation in Soil Fungal Communities across Paddy Fields in Subtropical China

mSystems, 2020
Fungi underpin almost all terrestrial ecosystem functions, yet our understanding of their community ecology lags far behind that of other organisms. Here, red paddy soils in subtropical China were collected across a soil depth profile, comprising 0-to-10-
