Eukaryotic cells change their shapes, actively segregate their DNA, and contain membrane networks, facilitated by a complex cytoskeleton containing actin filaments, microtubules made from tubulin, and other components. These filaments have ancient…

Characterisation of the bacterial and archaeal microbiota in processed colostrum collected from a spring-calving dairy herd

Lower-order streams in agricultural landscapes receive major anthropogenic nitrogen inputs. Streambed sediments host diverse microbial communities that can influence nitrogen (N) fluxes and water chemistry. Both bacterial and archaeal ammonia oxidizers…

Fluorescent probes as markers of cell envelope structure and function in halophilic archaea
