Nitrite and Nitrite Reductases: From Molecular Mechanisms to Significance in Human Health and Disease

, 2012
Nitrite, previously considered physiologically irrelevant and a simple end product of endogenous nitric oxide (NO) metabolism, is now envisaged as a reservoir of NO to be activated in response to oxygen (O-2) depletion.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, Volume 16, Issue 10, Page 1911-1924, October 2026.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Immunoinformatics‐Based Design of a Multi‐Epitope Vaccine Targeting a Conserved Copper–Associated Protein in Neisseria gonorrhoeae

Biotechnology and Applied Biochemistry, Volume 73, Issue 5, Page 2373-2387, October 2026.
ABSTRACT Neisseria gonorrhoeae poses an urgent public health challenge due to rapidly increasing antimicrobial resistance and the absence of an effective vaccine. Targeting conserved bacterial pathways involved in essential physiological processes may provide new opportunities for vaccine antigen discovery.

Antioxidant Responses to Dietary Supplementation With Non‐Enriched and Selenium‐Enriched Mushrooms and Selenized Yeast in Piglets

Molecular Nutrition &Food Research, Volume 70, Issue 19, 15 October 2026.
The findings highlight tissue‐specific responses to dietary selenium supplementation, with hepatic antioxidant modulation occurring without changes in plasma parameters, while selenium deposition patterns differed among tissues, emphasizing the complex relationship between selenium sources, metabolism, and antioxidant defense.

Multifactorial Role of Phytogenic CeO2 NPs in Crop Improvement and Stress Alleviation: A Mechanistic Overview

Plant-Environment Interactions, Volume 7, Issue 5, October 2026.
The graphical abstract illustrates how CeO2 nanoparticles help plants withstand biotic and abiotic stresses. Their application reduces excessive ROS through enhanced antioxidant defenses, whereas modulating stress signaling, phytohormones, and gene expression.

Long‐Term Low‐DO Operation Changes the Ammonia Oxidizer Community and Oxygen Kinetics

Water Environment Research, Volume 98, Issue 10, October 2026.
Lower dissolved oxygen reduces energy demand for wastewater treatment but slows ammonia removal. This study investigates a pilot process maintaining complete nitrification, documenting ammonia oxidizer adaptation to low dissolved oxygen. ABSTRACT Low–dissolved oxygen (DO) biological nutrient removal is an attractive option for energy and cost reduction,

Perspectives for pharmaceutical screening at XFEL sources using the example of Lassa virus endonuclease

Acta Crystallographica Section D, Volume 82, Issue 10, Page 1181-1194, October 2026.
To facilitate structure‐based drug development, XFEL sources are of paramount interest. Here, we analyse the feasibility and data quality of serial femtosecond X‐ray crystallography compound screening at Linac Coherent Light Source and compare it with PETRA III synchrotron experiments.

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 ...

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 ...
