“…Of particular interest was that the pine needle substrate contained significantly higher concentrations of the majority of the elements examined, with the only exceptions Be, Mg, Mo, Ni and Se. This observation is in accordance with previous findings demonstrating strong bioaccumulation in the needles of pine species not only as regards heavy metals [42,43] but also with respect to rare earth elements [44]. Grape marc plus cotton gin trash was also rich in most of the elements studied, presenting the highest concentrations of Be and Mg, whereas extracted olive press cake, nut shells and olive mill by-products were the substrates with the lowest element concentrations (Table 1).…”

“…This finding is indicative of the antagonistic relationship between P and the aforementioned elements as was previously reported in plants [65,73], while it also suggests that high P content might mitigate potential adverse effects related to the absorption of heavy metals by the fungus. The same type of correlation was recently reported between P and rare earth elements for the same mushroom species [44]. Moreover, the relationship existing between crude protein content and Se-through the pivotal role of the latter in the formation of selenoproteins (e.g., selenocysteine [74])-is confirmed by the findings of the present work, where a significant correlation was detected for both C. cylindracea and P. ostreatus (r = 0.70 and r = 0.78, p < 0.05, respectively).…”

Few data exist about the effect of substrates’ elemental content on the respective concentrations in cultivated mushrooms, on the degradation of lignocellulosics or on production parameters. Sixteen elements (14 metals and 2 metalloids) were measured by inductively coupled plasma mass spectrometry (ICP-MS) in Pleurotus ostreatus and Cyclocybe cylindracea mushrooms, and in their seven cultivation substrates composed of various plant-based residues. Results revealed a high variability in elemental concentration among substrates which generally led to significant differences in the respective mushroom contents. High bioconcentration factors (BCFs) were noted for Cd, Cu, Mg and Zn for both species in all substrates. BCF of each element was variously affected by substrates’ pH, crude composition, and p and K content. Significant positive correlations were demonstrated for Cu, Fe, Mn and Li concentrations vs. a decrease of cellulose and hemicellulose in P. ostreatus substrates, and vs. mushrooms’ biological efficiency. In the case of C. cylindracea, Be, Mg and Mn concentrations were positively correlated with the decrease of hemicellulose in substrates, while a significant positive correlation was also recorded vs. mushroom productivity. Finally, it was found that 15% to 35% of the daily dietary needs in Mg, Se and Zn could be covered by mushroom consumption.

“…Although analysis of elements has been the subject of numerous papers for the last 20 years [10,11], in the case of selected elements such an as Hf, Nb, Ta, Tm or W, literature data are still highly limited [12]. The development of analytical chemistry has allowed the content of these elements to be determined in different mushroom species [13,14]. The content of elements in particular mushroom species is highly diverse and is usually mushroom species-dependent [12].…”

The multi-elemental composition of 4 edible wild-growing mushroom species that commonly occur in Polish forests was compared to 13 cultivated mushroom species available in trade. A considerable variation in the macroelements content was revealed with cultivated species containing higher amounts of macroelements. The mean content of B, Co, Cr, Fe, Pb, Pr, Pt, Sb, Sm, Sr, Te, and Tm was higher in cultivated mushroom species, while the opposite was noted for Ba, Cd, Cu, Hg, La, Mo, Sc, and Zn. Selected cultivated forms exhibited increased content of Al (F. velutipes), As (H. marmoreus, F. velutipes), Ni (P. ostreatus, A. polytricha, H. marmoreus), and Pb (P. ostreatus, A. polytricha, F. velupites, and L. edodes). Wild-growing species, B. boletus, I. badia, and S. bovinus contained high Hg levels, close to or exceeding tolerable intakes. Compared to cultivated mushrooms, they also generally revealed a significantly increased content of Al (with the highest content in B. edulis and I. badia), As and Cd (with the highest content in B. edulis and S. bovinus in both cases). In turn, the cultivated mushrooms were characterized by a higher content of Ni (particularly in A. bisporus) and Pb (with the highest content in P. eryngii). The exposure risks may, however, differ between wild and cultivated mushrooms since the former are consumed seasonally (although in some regions at a high level), while the latter are available throughout the year. Both cultivated and wild-growing mushrooms were found to be a poor source of Ca and Mg, and only a supplemental source of K, Cu, Fe, and Zn in the human diet. These results suggest that mushrooms collected from the wild or cultivated, should be consumed sparingly. The study advocates for more strict monitoring measures of the content of toxic metals/metalloids in mushrooms distributed as food, preferentially through the establishment of maximum allowance levels not limited only to a few elements and mushroom species.

“…Usually all rare earths in different materials follow the same pattern, i.e., they are all enriched or depleted: fava Santorini’s [26]; Italian milk [30]; mushrooms substrates [31]. However, this pattern is differentiated by genetic factors as seen in two different mushroom species [31]. The production method could also differentiate the pattern as seen in game and farmedrabbits [25].…”

Greek Graviera Cheese Assessment through Elemental Metabolomics—Implications for Authentication, Safety and Nutrition

This study presents the comprehensive elemental profile of Greek Graviera (Gruyère) cheeses. In total, 105 samples from nine different geographic regions produced from sheep, goat and cow milk and their mixtures were assessed. Elemental signatures of 61 elements were investigated for determination of geographic origin and milk type. Regional and milk type classification through Linear Discriminant Analysis was successful for almost all cases, while a less optimistic cross validation exercise presented lower classification rates. That points to further research using a much larger sample set, increasing confidence for cheese authentication utilizing also bioinformatics tools under development. This is the first study reporting signatures of 61 elements in dairy products including all sixteen rare earth elements and all seven precious metals. Safety and quality were assessed regarding toxic and nutritive elements. According to both EU and USA regulations and directives, Graviera is a nutritional source for trace and macro elements with low levels of toxic elements.

Rare earth elements concentration in mushroom cultivation substrates affects the production process and fruit‐bodies content of Pleurotus ostreatus and Cyclocybe cylindracea

Abstract: The content of REEs in cultivation substrates and in mushrooms revealed that the bioaccumulation of elements differed in each fungus. The nature/origin of substrates seemed to affect the concentration of REEs in mushrooms to a considerable extent. © 2018 Society of Chemical Industry.
