In this transdisciplinary study, we investigated, using genomic tools and physico-chemical parameters, the effect of Moringa oleifera seed (MOS) on the removal of microorganisms and pharmaceutic residues (antibiotics), and also the development of antibiotic-resistant genes (ARGs) in water samples from a domestic wastewater treatment plant (WWTP) prototype. Water samples were analyzed with and without the addition of powder of MOS. The results showed that MOS addition reduced the total bacterial load from 1.

Background: Stannous fluoride has long been an effective antibacterial, anticaries, antisensitivity, and antigingivitis addition to toothpaste formulas. However, in the past its chemical properties in aqueous solution have made it difficult to stabilize with desirable results. The recent development of a novel formulation of 0.

Article Synopsis
- Sb(III) oxidation by microorganisms is crucial for antimony geochemical cycling and bioremediation, highlighting the role of Phytobacter sp. X4 as a novel bacterium that oxidizes Sb(III) under anaerobic conditions.
- The study showed that high Sb(III) concentrations lead to increased secretion of extracellular polypeptides (EPS), particularly polysaccharides, which help regulate the environmental response to Sb(III) toxicity.
- Functional groups on the cell surface help absorb Sb(III) to prevent its entry, while changes in the antioxidant system demonstrate the involvement of hydroxyl radicals and hydrogen peroxide in the anaerobic oxidation process, with qPCR revealing significant regulation of proteins that contribute to antimony resistance.
