In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

Some N2-fixing cyanobacteria form symbiosis with diverse protists. In the plankton two groups of diazotrophic symbioses are described: (1) a collective group of diatoms which associate with heterocystous cyanobacteria (Diatom Diazotroph Associations, DDA)

Quantifying Under‐Ice Phytoplankton Blooms in the Changing Arctic and Southern Oceans
Abstract Historically, polar marine phytoplankton were thought to primarily grow after the seasonal breakup of sea ice, when there is plentiful light available in the surface ocean. However, observations of substantial productivity under sea ice has called this assumption into question.

Iron and phosphorus co-limit nitrogen fixation in the eastern tropical North Atlantic [PDF]
The role of iron in enhancing phytoplankton productivity in high nutrient, low chlorophyll oceanic regions was demonstrated first through iron-addition bioassay experiments1 and subsequently confirmed by large-scale iron fertilization experiments2.

This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Biotic–Abiotic Hybrid Strategies for Photosynthetic Nitrogen Fixation and Green Ammonia Synthesis
Biotic‐abiotic photosynthetic systems integrate light‐harvesting semiconductors with nitrogenase's selective N2 reduction under ambient conditions, offering a sustainable alternative to conventional ammonia synthesis. Advancing rational interface design, efficient energy‐reaction coupling, and system integration is critical to realizing scalable, solar‐

Dynamics of diazotroph particle colonization in the Arctic Ocean. [PDF]
Abstract Global warming is causing sea ice retreat and intensifying algal blooms in the Arctic Ocean, in turn increasing nitrogen limitation in surface waters. Dinitrogen fixation by diazotrophic microorganisms, usually favored in low reactive nitrogen systems, may become an increasingly important source of nitrogen in the Arctic ...
