Linking crenarchaeal and bacterial nitrification to anammox in the Black Sea
Active expression of putative ammonia monooxygenase gene subunit A (amoA) of marine group I Crenarchaeota has been detected in the Black Sea water column.... |

New processes and players in the nitrogen cycle: the microbial ecology of anaerobic and archaeal ammonia oxidation
The element nitrogen (N) is an essential nutrient for all organisms, and as a critical component of proteins, N is fundamental to the structures and biochemical processes that define life. N is of such centrality that it has been suggested to be perhaps the best bio-signature…. |

Groundwater Ammonia and Nitrate Bioremediation
Based on our work, microbial driven bioremediation of ammonia and nitrate contaminated groundwater is now feasible and reasonable. Science’s understanding of the nitrogen cycle has changed dramatically in the past few years. Previously, fragile nitrifying and denitrifying bacteria were the focus. Recent studies show the majority of ammonia oxidation is driven by robust Crenarchaea and related Archaeal organisms, even at low oxygen levels. And evidence is accumulating that Archaea are also responsible for denitrification, even under aerobic conditions.....

Archaea improves Ammonia Removal
Ammonia removal is an important aspect of biological nutrient removal in wastewater treatment processes. However, due to process constraints, inhibiting compounds or more stringent discharge standards the ammonia removal rate can be insufficient.... |

Crenarchaeota colonize terrestrial plant roots
Microorganisms that colonize plant roots are recruited from, and in turn contribute substantially to, the vast and virtually uncharacterized phylogenetic diversity of soil microbiota. The diverse, but poorly understood, microorganisms that colonize plant roots mediate mineral transformations and nutrient cycles that are central to biosphere functioning.... |

The Prokaryotes
Prokaryotes are the original inhabitants of this planet, the first successful living organisms may have looked very like some of today's Archaea. Both Archaea and Bacteria evolved somewhere between 3 or 4 billion years ago, as far as we are able to tell from the fossil record. This means they have been around twice as long as the Protozoans and more than 3 times as long as animals..... |
