A unique bacteriohopanetetrol stereoisomer of marine anammox [PDF]

, 2020
Anaerobic ammonium oxidation (anammox) is a major process of bioavailable nitrogen removal from marine systems. Previously, a bacteriohopanetetrol (BHT) isomer, with unknown stereochemistry, eluting later than BHT using high performance liquid ...

Challenging protein purification from anammox bacteria

International Journal of Biological Macromolecules, 2006
The anaerobic ammonium oxidation (anammox) is a fascinating microbial pathway contributing to the global biogeochemical nitrogen cycle. The anammox pathway of nitrogen conversion can only be elucidated after the responsible proteins have been purified and characterised.

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to
