Solar light-driven complete mineralization of aqueous gram-positive and gram-negative bacteria with ZnO photocatalyst

TiO2 nanopowder and nanofilm catalysts in the disinfection and mineralization of S. aureus with solar-simulated radiation

“…This is because the TOC values, measured for the gross reaction mixture after 3 h, include living bacteria, broth organics and cell walls from the mineralized bacteria. As reported earlier, 16,47 the S. aureus bacteria have thick walls which resist photodegradation. The TOC value is thus expected to increase.…”

Potential Application of Agriculture by-Products in Heavy Metals Bioremediation

“…Heavy metals are dangerous because they are taken up and stored faster than they are broken down or extracted (metabolized) they tend to accumulate, and they alter the structure of bacterial cells by affecting their enzyme activity, and structure and attaching to the surface of the bacterial cell. The presence of Cu and Zn may have resulted from their release from the extensive use of anti-fouling paints by shipping activities found in the Suez Bay (Zyoud et al, 2019). It was found that; rice husk showed high efficiency for the sorption of the investigated.…”

Landfill fire impact on bee health: beneficial effect of dietary supplementation with medicinal plants and probiotics in reducing oxidative stress and metal accumulation

“…The adsorption of metals by bacteria takes place through the charges or bonds formed on the surface of their cell wall. Bacteria are divided into gram-positive or gram-negative bacteria depending on the composition and thickness of their cell wall (Zyoud et al 2019). Notably the cell wall of gram-positive bacteria has thicker peptidoglycan layers connected by amino acid bridges (Abdi and Kazemi 2015;Zyoud et al 2019).…”
