A master's thesis at the College of Science at the University of Basra discussed the use of some bacteria isolated from hydrocarbon-contaminated soils and water in Basrah Governorate to bio-produce silver nanoparticles and the use of these particles in cracking Congo red dye.

The letter of researcher Rawaa Rahim Yali showed the ability of the bacteria Pseudomonas aeruginosa to produce silver nanoparticles.

The thesis aims to manufacture silver AgNPs nanoparticles by bacteria and use them in the

The thesis concluded the ability of bacterial species isolated from sewage water and soils contaminated with hydrocarbons to produce silver AgNPs nanoparticles.

The thesis recommended the manufacture of different types of nanoparticles and the use of silver nanoparticles produced in the decomposition of different types of dyes, encouraging the use of environmentally friendly natural dyes, and limiting the use of chemical dyes.
