The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

Anaerobic ammonium oxidation (anammox) represents a promising technology for
wastewater nitrogen removal. Organics management is critical to achieving efficient and …

Despite the fact that heterotrophic nitrification was identified more than 100 years ago, the
biochemistry of heterotrophic nitrifiers is poorly known and their contribution to nitrification in …

Ammonia-oxidizing archaea (AOA) are one of the most abundant groups of microbes in the
world's oceans and are key players in the nitrogen cycle. Their energy metabolism—the …

Acetate is a major nutrient that supports acetyl-coenzyme A (Ac-CoA) metabolism and thus
lipogenesis and protein acetylation. However, its source is unclear. Here, we report that …

Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …

Nitrification is the aerobic process of the nitrogen cycle that converts ammonia to nitrate and
is facilitated by ammonia-oxidizing and nitrite-oxidizing microorganisms. Ammonia-oxidizers …

Reactive oxygen species (ROS) are omnipresent in the ocean, originating from both
biological (eg, unbalanced metabolism or stress) and non-biological processes (eg …

Besides the ecotoxicological consequences of microplastics and associated chemicals, the
association of microbes on plastics has greater environmental implications as microplastics …

Ammonia oxidation is a fundamental core process in the global biogeochemical nitrogen
cycle. Oxidation of ammonia (NH3) to nitrite (NO2−) is the first and rate-limiting step in …
