Biotic–Abiotic Hybrid Strategies for Photosynthetic Nitrogen Fixation and Green Ammonia Synthesis

ChemistryEurope, Volume 4, Issue 4, April 2026.
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‐

Salinity induced responses in the marine cyanobacterium Anacystis dimidiata

Ciencias Marinas, 1993
Growth and changes in biochemical composition were studied in the marine cyanobacterium Anacystis dimidiata, collected from a mangrove environment where salinities ranged from 5 to 40ppt. The cyanobacterium showed optimum growth at 2ppt salinity. At Iow

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, Volume 41, Issue 3, Page 520-539, April 2026.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Metatranscriptomic Sequencing of a Cyanobacterial Soil-Surface Consortium with and without a Diverse Underlying Soil Microbiome. [PDF]

, 2020
Soil surface consortia are easily observed and sampled, allowing examination of their interactions with soil microbiomes. Here, we present metatranscriptomic sequences from Dark Green 1 (DG1), a cyanobacterium-based soil surface consortium, in the ...

Seasonal nitrate drawdown transitions lake ecosystems from phosphorus to nitrogen deficiency in annual cycles

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Phytoplankton biomass is often limited by nitrogen (N) and/or phosphorus (P). Quantifying the relative availability of N and P in an ecosystem is useful in indicating nutrient limitation status. In subtropical lakes, nitrate availability generally follows a seasonal pattern with maxima in the late winter/early spring and minima in late summer ...

Green Synthesis of ZnO Nanoparticles From Spirulina platensis: Antimicrobial and Cytotoxic Evaluation With Molecular Docking Studies

ChemistryOpen, Volume 15, Issue 4, April 2026.
Algal‐extract‐derived ZnO nanoparticles show shape anisotropy and are bio capped by phytochemicals. These green‐synthesized NPs strongly inhibit S. aureus and K. pneumoniae biofilms. Molecular docking suggests stable binding of surface biomolecules to microbial targets, highlighting synergistic antibacterial mechanisms.

The Transcriptional Cycle Is Suited to Daytime N₂ Fixation in the Unicellular Cyanobacterium “Candidatus Atelocyanobacterium thalassa” (UCYN-A)

mBio, 2019
Symbiosis between a marine alga and a N2-fixing cyanobacterium (Cyanobacterium UCYN-A) is geographically widespread in the oceans and is important in the marine N cycle. UCYN-A is uncultivated and is an unusual unicellular cyanobacterium because it lacks

Toward Industrial Application of Cyanobacterial Biosorption: Insights From Real Electroplating Effluents

Water Environment Research, Volume 98, Issue 4, April 2026.
The study demonstrates that exopolysaccharide‐producing cyanobacteria are effective biosorbents for metals contained in electroplating wastewater. Ni uptake (2.3–2.9 mmol/g) was higher than for precious metals such as palladium (Pd) and gold (Au) (lower than 0.1 mmol/g). D. salina 16Som2 and Cyanothece sp. CE 4 showed the best performances.

The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...
