Abstract

Selenium nanoparticles are attracting the attention of researchers due to their multiple applications, including medicine. The biosynthesis of selenium nanoparticles has become particularly important due to the environmentally friendly character of the process and special properties of the obtained particles. The possibility of performing the biosynthesis of selenium nanoparticles via the living culture of starting from sodium selenite was studied. The bioaccumulation capacity of the culture, along with changes in the main biochemical parameters of the biomass, the ultrastructural changes in the cells during biosynthesis and the change in the expression of some genes involved in stress response reactions were determined. Protein, lipid and polysaccharide fractions were obtained from the biomass grown in the presence of sodium selenite. The formation of selenium nanoparticles in the protein fraction was demonstrated. Thus, culture can be considered a suitable matrix for the biosynthesis of selenium nanoparticles.

摘要

硒纳米颗粒因其包括医学在内的多种应用而吸引了研究人员的关注。由于该过程的环境友好特性以及所得颗粒的特殊性质，硒纳米颗粒的生物合成变得尤为重要。研究了从亚硒酸钠出发通过活培养物进行硒纳米颗粒生物合成的可能性。测定了培养物的生物积累能力，以及生物质主要生化参数的变化、生物合成过程中细胞的超微结构变化以及一些参与应激反应的基因表达的变化。从在亚硒酸钠存在下生长的生物质中获得了蛋白质、脂质和多糖组分。证明了在蛋白质组分中形成了硒纳米颗粒。因此，该培养物可被视为硒纳米颗粒生物合成的合适基质。
