Key players in the marine nitrogen cycle use cyanate and urea

The ammonia oxidizing archaea, or Thaumarchaeota, are among the most abundant marine microorganisms. Yet, scientists are still discovering which factors allow them to thrive in the ocean. A research team from the Max Planck ...

Utah soil's slippery grip on nutrients

Lawns in the Salt Lake Valley up to 100 years old are not yet saturated in the nutrient nitrogen, which is added by fertilizer, according to a new study from University of Utah researchers. The result is surprising, since ...

Continental microbes helped seed ancient seas with nitrogen

Like our oceans, today's continents are brimming with life. Yet billions of years ago, before the advent of plants, continents would have appeared barren. These apparently vacant land forms were believed to play no role in ...

Microbes with a reserve pack of sulfur

SUP05 bacteria are often found in places where there is really no basis for life for them. Researchers in Bremen have now discovered that they are even quite active there – possibly with consequences for the global nitrogen ...

Understanding microbial competition for nitrogen

Nitrogen is a hot commodity in the surface ocean. Primary producers including phytoplankton and other microorganisms consume and transform it into organic molecules to build biomass, while others transform inorganic forms ...

New method measures rare traces of a volatile gas

The gas nitrogen monoxide (NO) belongs to the group of nitrogen oxides, infamous as toxic emissions in urban agglomerations. But NO is also produced in nature and plays a role in the nitrogen cycle, which is essential for ...

Research reveals a new survival strategy in key bacteria

New research shows that a bacteria and promising microbial cell factory will not immediately shut down when deprived of nitrogen – instead 'waiting' until absolutely necessary to stop functioning.
