S. marcescens is a motile organism and can grow in temperatures ranging 5–40 °C (41–104 °F) and in pH levels ranging from 5 to 9. It is differentiated from other Gram-negative bacteria by its ability to perform casein hydrolysis, which allows it to produce extracellular metalloproteinases which are believed to function in cell-to-extracellular matrix interactions.
Its property of not having a carbon backbone, but a chemically robust silicon backbone instead, reduces its potential as a food source for dangerous waterborne bacteria such as Legionella. Non-dyed silicone rubber tape with an iron(III) oxide additive (making the tape a red-orange colour) is used extensively in aviation and aerospace wiring ...
This silicone dish drying mat has a ribbed design that elevates your dishes and allows maximum air flow to keep bacteria at bay. It’s also really easy to clean and store once you’re done using it.
Thallium compounds such as thallium sulfate have been used for impregnating wood and leather to kill fungal spores and bacteria, and for the protection of textiles from attack by moths. [24] Thallium sulfate has been used as a depilatory and in the treatment of venereal disease, skin fungal infections, and tuberculosis.
A dry-cleaning expert explains what dry cleaning is for, exactly how dry cleaning works, and what's in dry cleaning, including chemicals to avoid.
A 2021 report from the California Office of Environmental Health Hazard Assessment found that kids who have food dyes, including red dye No. 3, can become more hyper than usual and have difficulty ...
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.
