In this work, the photokilling of Escherichia coli using a “one-pot” synthesized suspension of anatase crystallized nanoparticles is evaluated. Preliminary to the biological tests concerning the antibacterial efficiency, the fabricated suspension, using a derived solgel process in soft chemistry condition, is characterized. Structural properties of the nanoparticles are investigated using.

An experiment devised in Griffith University’s Centre for Quantum Dynamics has for the first time demonstrated Albert Einstein’s original conception of "spooky action at a distance. their use of.

The researchers found one compound, called C10, that did not kill the TB bacteria but prevented them from forming a biofilm. Further experiments showed that blocking. of isoniazid-resistant TB.

When Griffith injected mice with the S strain, which he discovered were encapsulated, they died. When he injected them with the R strain, they did not die. In trying to determine what factor was responsible for the S strain’s virulence, Griffith heat-killed the S bacteria to destroy the capsule.

Sulfide toxicity is a common disease generally associated with iron toxicity which occurs in rice fields when the Sulfate-Reducing Bacteria (SRB) produce sulfides ions in anaerobic conditions. The high quantity of sulfides ions in the soil solution upsets the mineral element balance in the rice, affects its growth and causes crop yield losses.
