“…Despite its relevant characteristics, Se is not present in appropriate levels in most types of food and this low ingestion level has been associated with a massive list of direct and indirect negative health effects. 6,[8][9][10][11] About half of the world population suffers from the malnutrition of Fe, Zn, Ca, I and Se. 8 Hence, increasing the concentration of bioavailable elements in edible crop tissues (biofortification) has become a promising strategy to increase the intake of some micronutrients.…”

“…The authors concluded that sprouted wheat with high levels of selenomethionine for bread-making should contain relatively low amylase activity. Egressy-Molnár et al 9 evaluated the analogy in Se enrichment and Se speciation between selenized yeast and lion's mane mushroom. The results showed that the high selenomethionine content and the presence of Se-adenosyl compounds in fortified mushroom opened the possibility for a functional food alternative to selenized yeast based dietary supplements.…”

The effect of selenate and selenite enrichment on mineral composition of a red type of lettuce cv. "Veneza roxa" was evaluated using inductively coupled plasma-optical emission spectroscopy (ICP OES), molecular modeling and principal component analysis (PCA). Both Se species did not show toxicity, while selenate promoted the greatest Se accumulation by the plant. There was an increase of 886 µg of Se per 100 g of fresh sample at different concentrations of selenate, but for selenite the maximum variation was only of 114 µg per 100 g. Selenate promoted the absorption of Mo and S and the reduction of K, Mn and P, meanwhile selenite increased Mn and decreased Mo accumulation. Copper and Fe absorption was negatively affected, Ca and Mg showed a slight increase, and Na and Zn were not affected by Se species. Despite the changes in the nutritional balance, Se-enriched lettuce can still be considered a potential dietary source of this essential element.

“…Organic Se-containing compounds may exhibit anticarcinogenic activity, and their bioavailability to human beings and animals are considered to be high ( Chun et al, 2006 ; Suhajda et al, 2000 ). Recently, there has been increasing interest in using selenized mushrooms as a source of Se supplementation ( Egressy-Molnár et al, 2016 ; Maseko et al, 2013 ; Rzymski et al, 2016 ). Mushrooms have long been appreciated for their flavor and texture, as a nutritious food, and as a source of biologically active compounds ( Cheung, Cheung & Ooi, 2003 ; Yan & Chang, 2012 ).…”

Recently, selenium (Se) enriched mushrooms have been exploited as dietary Se supplements, but our knowledge of the metabolic process during the Se enrichment process is far from complete. In this study, the uptake, tolerance and reduction of selenite in a widely cultivated mushroom, Flammulina velutipes, was investigated. The results showed that pH variation (from 5.5–7.5), metabolic inhibitor (0.1 mM 2,4-DNP) and P or S starvation led to 11–26% decreases in the selenite uptake rate of F. velutipes. This indicates that a minor portion of the selenite uptake was metabolism dependent, whereas a carrier-facilitated passive transport may be crucial. Growth inhibition of F. velutipes initiated at 0.1 mM selenite (11% decrease in the growth rate) and complete growth inhibition occurred at 3 mM selenite. A selenite concentration of 0.03–0.1 mM was recommended to maintain the balance between mycelium production and Se enrichment. F. velutipes was capable of reducing selenite to elemental Se [Se(0)] including Se(0) nanoparticles, possibly as a detoxification mechanism. This process depended on both selenite concentration and metabolism activity. Overall, the data obtained provided some basic information for the cultivation of the selenized F. velutipes, and highlighted the opportunity of using mushrooms for the production of Se(0) nanoparticles.
