The widespread use of antibiotics has led to the emergence of multidrug-resistant bacterial strains, and therefore a current concern for food safety and human health. The interest for new antimicrobial substances has been focused toward metal oxide nanoparticles. Specifically, dioxide TiO2 has been considered as an attractive antimicrobial compound due to its photocatalytic nature
It has no specific titanium content. Titanium minerals occur in alluvial and volcanic formations. Deposits usually contain between 3 and 12 percent heavy minerals, consisting of , leucoxene, zircon, and monazite. Mining and concentrating. Although workable known reserves of rutile are diminishing, ilmenite deposits are abundant
