“…Studies have shown that Se NPs have broad-spectrum antibacterial effects that target both gram-positive and gram-negative bacteria ( Indhira et al, 2023 ). The antibacterial activity of Se NPs is attributed to several mechanisms, including disintegration of the bacterial cell wall and membrane, hampering bacterial metabolism and impeding bacterial DNA replication ( Abadi et al, 2022 ). When compared to traditional antibiotics, Se NPs have been shown to have advantages such as a smaller size, higher surface area-to-volume ratio, and greater ability to penetrate bacterial cell walls, which make them effective antimicrobial agents.…”

Introduction:Bacillus species are known for their ability to produce nanoparticles with various potential applications.Methods: In this study, we present a facile approach for the green synthesis of selenium nanoparticles (Se NPs) using the biogenic selenate-reducing bacterium Bacillus paramycoides 24522. We optimized the growth conditions and sodium selenite reduction efficiency (SSRE) of B. paramycoides 24522 using a response surface approach.Results: Se NPs were synthesized by reducing selenite ions with B. paramycoides 24522 at 37 °C, pH 6, and 140 r/min, resulting in stable red-colored Se NPs and maximal SSRE (99.12%). The synthesized Se NPs demonstrated lethality against Staphylococcus aureus and Escherichia coli with MICs of 400 and 600 μg/mL, and MBCs of 600 and 800 μg/mL, respectively, indicating the potential of Se NPs as antibacterial agents. Furthermore, the Se NPs showed promising antioxidant capabilities through scavenging DPPH radicals and reducing power.Discussion: This study highlights the environmentally friendly production of Se NPs using B. paramycoides 24522 and their possible applications in addressing selenium pollution, as well as in the fields of environment and biotechnology.

“…Carbohydrates are rich in reducing groups, such as hydroxy and carboxy, which can bind and reduce metal atoms, thereby acting as reducing agents. Moreover, due to the supramolecular interactions by inter- and intra-molecular hydrogen bonding, they can stabilize formed nanoparticles and prevent further agglomeration, acting as capping agents [ 16 , 31 ]. The potential of secretory carbohydrates from C. vulgaris was tested by the removal of biomass from the culture and used for the synthesis of FeOOH NPs [ 32 ].…”

Over the years, microalgae have been a source of useful compounds mainly used as food and dietary supplements. Recently, microalgae have been used as a source of metabolites that can participate in the synthesis of several nanoparticles through inexpensive and environmentally friendly routes alternative to chemical synthesis. Notably, the occurrence of global health threats focused attention on the microalgae application in the medicinal field. In this review, we report the influence of secondary metabolites from marine and freshwater microalgae and cyanobacteria on the synthesis of nanoparticles that were applied as therapeutics. In addition, the use of isolated compounds on the surface of nanoparticles to combat diseases has also been addressed. Although studies have proven the beneficial effect of high-value bioproducts on microalgae and their potential in medicine, there is still room for understanding their exact role in the human body and translating lab-based research into clinical trials.

“…Furthermore, natural compounds are abundant in all parts of the plant, which provides suitable conditions for the synthesis of Bio-SeNPs ( Jadoun et al, 2020 ; Ikram et al, 2021 ). In the synthesis of Bio-SeNPs, plant extracts provide three major groups of substances, including reducing agents, stabilizers, and capping agents ( Abadi et al, 2022 ; Khan et al, 2022 ). In addition, plant extracts are abundant in antibacterial substances such as phenols, phenolic acids, terpenoids, and alkaloids ( Alibi et al, 2021 ), which contribute to the synthesis and bioactivity of antibacterial nanomaterials.…”

Effective control of foodborne pathogen contamination is a significant challenge to the food industry, but the development of new antibacterial nanotechnologies offers new opportunities. Notably, selenium nanoparticles have been extensively studied and successfully applied in various food fields. Selenium nanoparticles act as food antibacterial agents with a number of benefits, including selenium as an essential trace element in food, prevention of drug resistance induction in foodborne pathogens, and improvement of shelf life and food storage conditions. Compared to physical and chemical methods, biogenic selenium nanoparticles (Bio-SeNPs) are safer and more multifunctional due to the bioactive molecules in Bio-SeNPs. This review includes a summarization of (1) biosynthesized of Bio-SeNPs from different sources (plant extracts, fungi and bacteria) and their antibacterial activity against various foodborne bacteria; (2) the antibacterial mechanisms of Bio-SeNPs, including penetration of cell wall, damage to cell membrane and contents leakage, inhibition of biofilm formation, and induction of oxidative stress; (3) the potential antibacterial applications of Bio-SeNPs as food packaging materials, food additives and fertilizers/feeds for crops and animals in the food industry; and (4) the cytotoxicity and animal toxicity of Bio-SeNPs. The related knowledge contributes to enhancing our understanding of Bio-SeNP applications and makes a valuable contribution to ensuring food safety.
