“…The selenium concentration in unenriched substrate was found to be higher (1.960.8 mg Se/g dw) than in the earlier reports which lay in the range of 0.09-0.19 mg Se/g dw in different substrates (27,28) and the resulting concentrations in fruiting bodies were in the range of 2.9-5.2 mg Se/g dw, which is almost comparable to the range (0.12-3.4 mg Se/g dw) of selenium conentartion in wild and edible species of Pleurotus (29)(30)(31). The fruiting bodies (first flush) of all species of Pleurotus harvested from Se-rich wheat straw containing a total Se concentration of 24.060.2 mg Se/g dw, were noted to accumulate significantly higher (p,0.0001) selenium as compared to control mushrooms grown on control wheat straw (1.960.8 mg Se/g dw).…”

“…The fruit bodies of P. ostreatus and P. pulmonarius strains were collected from 19 mushroom farms. The tested fruit bodies were obtained from each mushroom grower in several cultivation cycles each year Bernaś et al 2006;Maihara et al 2008;Muñoz et al 2005;Kalač 2010;Costa-Silva et al 2011;Zhu et al 2011) b P. florida (Alam et al 2008;Mallikarjuna et al 2013) c P. djamor (Rodriguez Estrada andRoyse 2007, Guo et al 2007;Lee et al 2009, Mallikarjuna et al 2013 d P. citrinopileatus (Rodrigues et al 2015) e P. eryngii (Rodriguez Estrada andRoyse 2007, Akyüz andKirbağ 2010;Zhu et al 2011) f P. pulmonarius (Oliveira Silva et al 2002;Vetter 2003, 2005, Borovicka et al 2011 in the period 2009-2015.

“…Studies of cultivated P. ostreatus from the European market by Costa-Silva et al (2011) showed that Se was at 0.10 ± 0.01 to 0.26 ± 0.20 mg kg −1 dm, while the Se content of samples from the USA was 0.2 mg kg −1 dm (Hong et al 2011). Cultivated mushrooms A. bisporus, P. ostreatus, P. florida, P. eryngii, and L. edodes contained As in amounts ranging between 0.009 and 0.210 mg kg −1 dm (Maihara et al 2008).…”

Considering the worldwide popularity of cultivated Pleurotus mushrooms as food, analyses of their chemical composition are required to ensure product safety. The aim of this study was to compare the content of 62 elements in fruit bodies of six cultivated species of the genus Pleurotus (five strains of Pleurotus ostreatus, Pleurotus eryngii, Pleurotus djamor, Pleurotus citrinopileatus, Pleurotus florida, and Pleurotus pulmonarius), collected from their producers between 2009 and 2015. Only 31 elements (Al, As, B, Ca, Cd, Cr, Cu, Er, Fe, In, K, Lu, Mg, Mn, Na, Nd, P, Pb, Pt, Re, Rh, Sc, Se, Sr, Te, Th, Ti, Tm, U, Zn, and Zr) were detectable in the tested Pleurotus species in each year of their collection. The obtained results revealed three significantly diverse groups with similar abilities to accumulate 31 elements within 7 years of mushroom production. The species and strains were grouped as follows: P. florida and P. pulmonarius (first group); P. ostreatus HK35, P. ostreatus 930, P. eryngii, and P. djamor (second group); and P. ostreatus 80, P. ostreatus H195, P. ostreatus K22, and P. citrinopileatus (third group). In spite of differences between the tested Pleurotus species and strains, presented in the form of graphical Heatmaps, the intake of these mushrooms was not related with any health risk for consumers.

“…Mushrooms usually contain small amounts of Se, but some species have the capacity to accumulate the element (COSTA-SILVA et al, 2011;KALAČ, 2013). The addition of Se to the substrate resulted in an increase of its content in the fruiting bodies (Tables 1-3).…”

The phenolic and fl avonoid contents and composition and the antioxidant ability in Hericium erinaceus, Ganoderma lucidum, and Agrocybe aegerita under selenium (Se) addition to growth medium were studied. The contents of total Se in fruiting bodies of controls (0 mM of Se) were 4.58 (A. aegerita), 8.53 (G. lucidum), and 14.29 (H. erinaceus) mg kg -1 dry weight (DW), and was signifi cantly increased by Se enrichment of substrate. The total phenolics in fruiting bodies of controls of H. erinaceus, G. lucidum, and A. aegerita were signifi cantly lower (17.10, 28.11, and 16.05 mg of gallic acid equivalent (GAE)/g of extract, respectively) than for Se-rich mushrooms (26.29, 40.29, and 20.07 mg GAE/g of extract, respectively). Total fl avonoid content for H. erinaceus, G. lucidum, and A. aegerita increased after Se supplementation from 368.6 to 445.6, 469.9 to 627.7, and 318.1 to 393.9 μg g -1 of extract, respectively. The results show that the mushrooms have superior antioxidant properties after Se addition, because the scavenging ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals was improved.
