Advances in the Study of Selenium‐Enriched Probiotics: From the Inorganic Se into Se Nanoparticles

Abstract

Selenium (Se) is a momentous metallic element that plays an irreplaceable role in biochemical activities. Se deficiency remains a nutritional challenge across the world. Organic Se supplementation is the most effective treatment means for Se deficiency. Organic Se transformed from Se‐enriched probiotics show outstanding excellent properties in antibacteria, anti‐oxidation, anti‐inflammation, and immunoregulation. Studying the influencing factors for Se enrichment capacity and enrichment mechanisms of Se‐enriched probiotics is conducive to the exploit of more potent Se‐enriched probiotics. Se‐enriched probiotics transform inorganic Se into Se nanoparticles (SeNPs), which have been widely used in animal husbandry and biomedical field. In this paper, the novel development of Se‐enriched probiotics is reviewed, and the bioactivities of SeNPs are assessed, so as to display their potential application prospects. The excellent role of SeNPs in anti‐oxidation is summarized, and the mechanism by which SeNPs improve Se deficiency and boost animal health is explained.

The Clothes Matter—Exploiting Agronomical Functions of Trichogenic Selenium Nanoparticles Sharing Activities with Biological Systems Wherein (Were) Formed

“…Due to its biological characteristics (resulting from its physical and chemical properties), Se is regarded as an element of great potential in various scientific fields, such as biomedical, food, agricultural, and environmental [6][7][8][9]. Selenium has not been classified…”

Biogenic Selenium Nanoparticles Synthesized Using Alginate Oligosaccharides Attenuate Heat Stress-Induced Impairment of Breast Meat Quality via Regulating Oxidative Stress, Metabolome and Ferroptosis in Broilers

“…On the other hand, it has been demonstrated that dietary Se deficiency induces oxidative stress, inflammatory damage, and apoptosis in a variety of tissues [14], and adversely affects broiler performance [15]. As a new form of Se supplement, selenium nanoparticles (SeNPs) can maximize the beneficial effects of Se because of their high surface activity and nanoscale effect [16]. Compared with organic and inorganic selenium, SeNPs have lower toxicity and higher biological activity [17].…”
