Summary: In recent years, microbial conversion of inorganic selenium into a safe and efficient form of organic selenium has been a focus of research. Selenium nanoparticles derived from nanotechnology offer higher safety, absorption, and biological activity compared to other selenium forms. This paper reviews the conversion of inorganic selenium to less toxic organic selenium and the biosynthesis of selenium nanoparticles by microbes. The synthesis method, potential mechanism, and characterization of selenium in different forms are also discussed.

Summary: The current study aimed to investigate the response of soybean plants to biofertilization and selenium supplementation treatments under galaxolide contamination of soil. The results showed that biofertilization and selenium supplementation treatments led to a decrease in oxidative stress in contaminated soil, resulting in improved physiological and biochemical traits in soybean plants. Furthermore, the combined treatment of biofertilization and selenium supplementation showed even better improvement in plant adaptation and tolerance against galaxolide contamination.

Summary: In this work, selenium nanoparticles stabilized with cocamidopropyl betaine were synthesized for the first time. Positively charged Se NPs had a cocamidopropyl betaine shell, while negatively charged Se NPs were formed by SeO32- ions. Different ions influenced the stability of Se NPs, following the Schulze-Hardy rule. The stability of Se NPs solutions was also affected by the active acidity of the medium.

Summary: A novel microwave-assisted green synthesis of selenium nanoparticles (SeNPs) using yeast extract as a non-toxic reducing and capping agent was presented. The effects of synthesis and gastrointestinal digestion conditions on the size distribution and concentration of biogenic Se particles were evaluated. It was found that the size of SeNPs varied depending on the synthesis conditions, and their size changed after incubation in simulated gastric juice but returned to the initial value after simulated intestinal juice addition. Biomolecules in yeast extract were identified and found to play a predominant role in the synthesis of SeNPs using LC Orbitrap ESI MS. This study provides important insights into the formation and behavior of SeNPs under gastrointestinal conditions, which is crucial for their potential use as a selenium source.

Summary: In this study, Morchella sextelata polysaccharide (MSP) was used as a stabilizer for the synthesis of selenium nanoparticles (SeNPs). The synthesized MSP-SeNPs exhibited red color, spherical shape, and amorphous nature. They showed high scavenging activity against DPPH and ABTS radicals, and significant anti-proliferation effect on HepG2 and Hela cancer cells. The mitochondria-dependent apoptosis pathway was identified as the mechanism of action.

Summary: Selenium is an essential element for human health, incorporated into selenocysteine in the body and used to synthesize selenoproteins. While it has beneficial properties, excessive intake can lead to toxicity. Selenium nanoparticles are a less toxic alternative for delivering drug payloads to specific cells, with potential applications in cancer therapy.

Summary: This study aimed to evaluate the effect of different selenium application methods (soil or foliar) and sources (organic or inorganic) on the total selenium content and speciation in selenium-enriched soybean grains. The results showed that all treatments with inorganic selenium increased the selenium content in grains compared to the control. More than 80% of the total selenium was present as selenomethionine (SeMet), and the speciation was influenced by the selenium source and application method. The treatments using inorganic selenium, applied via soil or foliar, produced the highest content of SeMet in soybean grains. Finally, the preservation of selenium species in products derived from soybean grains should be evaluated.

Summary: Recent findings suggest that the biosynthesis of selenium nanoparticles (SeNPs) in plants might be common. By growing a variety of plants in controlled conditions and analyzing them, we found strong evidence that SeNPs are widely present in vegetables. This indicates that SeNPs are common ingredients in plant-based food and are therefore consumed by most humans daily.

Summary: It has been discovered that certain hydroponically grown plants can synthesize selenium nanoparticles (SeNP) through biosynthesis when exposed to selenite. These SeNP have a narrow size distribution and contain approximately 2 million selenium atoms, proving the possibility of green synthesis of SeNP in both plant extracts and living organisms. This research provides new insights into the biochemistry of selenium in plants and its impact on nutrition, food sciences, and medicine. To the best of our knowledge, this is the first report on the synthesis of elemental nanoparticles, specifically selenium nanoparticles, by living plants.

Summary: Plant metabolites have a significant impact on soil microbiomes. Despite some studies shedding light on plant-microbe interactions, our understanding of how plants recruit their microbiome remains limited. In this review, we discuss the dynamic progress of typical metabolites shaping microbes through various factors, including physiographic, cultivar, phylogeny, and environmental stress. Several types of metabolites, such as plant primary metabolites (PPMs), phytohormones, and plant secondary metabolites (PSMs), are reviewed. The microbes assembled by plant metabolites, in turn, exhibit beneficial effects on plants and have been widely applied in agriculture. Furthermore, we highlight existing issues and future research directions, such as unclear mechanisms, limited species, simplistic components, and disregard for absolute abundance. This review may inspire readers to further investigate plant-metabolite-microbe interactions.

Summary: Bamboo is nutritionally valuable globally due to its high calorie and nutritional fiber content and low cholesterol. However, it has been found that bamboo shoots also contain significant amounts of heavy metals, including arsenic. In this study, researchers investigated the possible attenuation of arsenic toxicity in bamboo plants through the co-application of iron oxide nanoparticles and selenium nanoparticles. The results showed that the co-application significantly improved antioxidant enzyme activities, total flavonoid and phenolic content, and various physiological and growth parameters of the bamboo plants. The most effective approach for increasing bamboo's ability to recover from arsenic toxicity was the concurrent use of selenium nanoparticles and iron oxide nanoparticles.
