Bacterial Contribution to Hydrogen Peroxide Decomposition in Lake Erie Cyanobacterial Harmful Algal Bloom Communities Is Dependent on Bloom Stage

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
A seasonal time series metatranscriptome dataset suggests that neutralising hydrogen peroxide in Microcystis blooms requires a complex division of labour that is further complicated by seasonality and bloom development. ABSTRACT Cyanobacterial harmful algal blooms (cHABs) are expanding globally and often involve toxin‐producing species such as ...

Comparative analysis of NR and NiR gene families reveals nitrite formation mechanisms in two Toona species

Chemical and Biological Technologies in Agriculture
Background Toona sinensis and Toona ciliata both belong to the same genus in the Meliaceae family; however, the nitrate and nitrite contents in T. sinensis are significantly higher than those in T. ciliata.

Microbial Community Restructuring Under Zinc Oxide Nanoparticle Stress in Membrane Bioreactors

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Long‐term ZnO nanoparticle exposure induced extracellular stress responses and restructured microbial communities, with reduced taxonomic and phylogenetic richness and loss of key nitrogen‐transforming taxa. These ecological changes were accompanied by impaired nitrification, demonstrating that prolonged ZnO exposure can compromise the functional ...

Biofloc‐based aquaculture: From monoculture to integrated systems

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract The demand for high‐quality protein has been growing in recent years, led by population growth. The development of aquaculture has been considered one of the solutions to ensure food security worldwide. New farming technologies have been promoted to increase productivity and, at the same time, minimize environmental impacts.

Effects of dietary nitrate supplementation on peak oxygen uptake following 10 days of Ramadan fasting in healthy adults

Experimental Physiology, Volume 111, Issue 10, Page 4636-4645, 1 October 2026.
Abstract Ramadan is a sacred religious practice observed by Muslims that involves abstaining from food and water from sunrise to sunset for 1 month. Prior work has reported that peak oxygen uptake (V̇O2peak${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{peak}}}}$) can decline during Ramadan in parallel with reduced physical activity.

The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.
