Among modern various fields, nanoparticles are widely used in the medical and cosmetic industries. There are various ways to synthesize nanoparticles from Lactobacillus. Selected strains of microorganisms are effective and environmentally friendly substitutes for the synthesis of nanoparticles. One of the most important examples of the synthesis of nanoparticles is gold, which can be obtained by a simple redox reaction carried out in aqueous solution [1].
Another equally well-known metallic element for the nanoparticle synthesis is titanium oxide (TiO2). The biosynthesis of TiO2 is caused by ecological representatives of the human microflora, such as Lactobacillus sp. You can also use an alternative mechanism of TiO2 nanoparticle biosynthesis, in which pH and the partial pressure of hydrogen gas (rH2) or the redox potential of the culturing solution are one of the important components in the process [2].
One of the vital metals for humanity is silver thanks to its antibacterial properties. Swift and environmentally friendly biosynthesis of silver nanoparticles using lactic acid bacteria is an economical way of finding solution, and any research in this area is promising [3, 4].
Zinc nanoparticles are particularly important for biological applications, as ZnO is listed as a generally accepted safe (GRAS) material [5].
Nanoparticle production is a unique biotechnological practice. This is a complex and multi-stage process. It is important for the development of medicine in the country. Current methods of biosynthesis are truly cost-effective and capable of producing nanoparticles. Optimization of modern methods of nanoparticle production is an urgent task in the field of biotechnology.
