Abstract: Selenium is an essential micro-nutrient for living organisms, but elevated concentrations of it in water can adversely affect health. Nitrate is often found in selenium-contaminated water and negatively correlates with selenium removal. In this study, we investigate the effect of nitrate co-existence on selenium bioremediation in chemically modified zeolite columns. Dynamic sorption-reduction experiments were conducted using natural and iron-coated zeolite columns to remove selenite and selenate oxyanions sepa… Show more

“…Therefore, it was expected to find 37 ASVs and 27,507 reads belonging to the order Veillonellales-Selenomonadales (phylum Firmicutes) in T. conica samples, while none were detected in T. swinhoei . These bacteria, known for their selenium-reducing capabilities, include species such as Megaspheara , notably prevalent in wastewater rich in selenium ( 39 ). In addition, Firmicutes are known to harbor a notable number of organisms that exhibit all three traits for selenium utilization and use a wide array of selenoproteins ( 40 ).…”
