Enhanced Photocatalytic Activity of Ag‐Doped WO3 for Antibiotic and Bacterial Removal in Fishponds

Aquaculture Research, Volume 2025, Issue 1, 2025.
A nanocomposite of Ag/WO3 was synthesized through a two‐step process: first, the hydrothermal synthesis of WO3 using Na2WO4, followed by gamma irradiation to dope the material with silver nanoparticles (Ag). To study the effect of silver doping, three different Ag+ concentrations −1, 2, and 3 mmol were introduced to a fixed 20 mmol concentration of WO3.

A Comprehensive Review of Antibiotics and Antimicrobial Resistance in the Aquaculture Sector of the World and Bangladesh

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Antibiotics are molecules produced by a microbe to inhibit the growth of another microbe. Due to prolonged improper use, the situation in which these antibiotics do not work effectively on these microbes is termed antibiotic resistance or antimicrobial resistance (AMR).

Genes for selenium dependent and independent formate dehydrogenase in the gut microbial communities of three lower, wood-feeding termites and a wood-feeding roach [PDF]

, 2011
The bacterial Wood-Ljungdahl pathway for CO_2-reductive acetogenesis is important for the nutritional mutualism occurring between wood-feeding insects and their hindgut microbiota. A key step in this pathway is the reduction of CO_2 to formate,
