“…Another characteristic is valuable in the region of polysaccharides vibrations between 1150-796 cm −1 (Table 3). More specifically, the bands at about 807 cm −1 and 930 cm −1 are corroborating for mannan [α (1-6) linked backbone with α (1-3) and α (1-2) linked branches] a type of glucan that is one component of fungal cell walls and chitin (Nacetylglucosamine based polymer), respectively [64]. A weak shoulder at around 1740 cm −1 indicated the presence of cell membrane phospholipids [61].…”

Valorization of Hazelnut Shells as Growing Substrate for Edible and Medicinal Mushrooms

Recently, the cultivation of hazel is undergoing a large expansion. Italy is the world’s second largest producer of hazelnuts, with a production of around 98,530 tons in 2019. The processing of hazelnuts produces large amounts of waste, especially woody pericarps, due to the cracking process, generally used for domestic heating, causing air pollution. The high lignin content present in the pericarps makes them a suitable substrate for the cultivation of edible and medicinal mushrooms. To this aim, Ganoderma lucidum, Lentinula edodes, and Pleurotus cornucopiae were grown and cultivated on different hazelnut-shell-based substrates: Hazelnut Shell (HS), Hazelnut Shell and Wheat Straw (HS-WS), and Wheat Straw mixed with Beech Chips (WS-BC) as control. In vitro mycelial grow rate, the degradation capacity of the lignocellulosic fraction, the biological efficiency, and the qualitative differences between mushrooms growing on different substrates by using Attenuated Total Reflectance–Fourier transform infrared (ATR-FTIR) spectroscopy were investigated. Our results suggested the ability of G. lucidum, L. edodes, and P. cornucopiae to grow and decay the lignocellulosic fraction of HS. Cultivation trials showed a similar biological efficiency but a different Fruiting Body Production (FBP) in the presence of HS with respect to the control. ATR-FTIR analysis provided a chemical insight for the examined fruiting bodies, and differences were found among the substrates studied. These results provide attractive perspectives both for more sustainable management and for the improvement of mushroom cultivation efficiency.

Fourteen different Pleurotus ostreatus cultivars (Po_1–Po_14) were tested for free amino acid content (fAA), total polyphenol content (TPC), and antioxidant capacity (Ferric Reducing Ability of Plasma—FRAP) to select the cultivars with the most favorable traits. Automatic amino acid analyzer (fAA) and spectrophotometric assay (TPC, FRAP) results as well as Fourier-transform near infrared (FT-NIR) spectra were evaluated with different chemometric methods (Kruskal–Wallis test, Principal Component Analysis—PCA, Linear Discriminant Analysis—LDA). Based on total free amino acid concentrations and FRAP values, the Po_2 cultivar was found to be the most favorable. Types Po_3, Po_8, Po_10 and Po_12 were separated using PCA. Based on the spectral profile, they may contain polyphenols and reducing compounds of different qualities. LDA classification that was based on the concentrations of all free amino acids, cysteine, and proline of the cultivars was performed with an accuracy of over 90%. LDA classification that was based on the TPC and FRAP values was performed with an accuracy of over 83%.

“…Regarding the vitamins content, its represent the only vegetarian source of vitamins D [1] and an important source of B group vitamin [2]. Moreover, mushrooms serve also as vegetarian source of protein [3]. On the other hand, wild mushrooms are thought to be richer in flavor, taste, texture, nutrition and medical effects [4].…”

Edible mushrooms have been recognized as highly nutritional food for a long time, due to their specific flavor, texture and also for therapeutic effects. This study proposes a new simple approach, based on FT-IR analysis, followed by statistical methods, in order to differentiate three wild mushrooms species from Romanian spontaneous flora, namely Armillaria mellea, Boletus edulis and Cantharellus cibarius. The preliminary data treatment consisted of data set reduction with principal component analysis (PCA), which provided scores for the next methods. Linear discriminant analysis (LDA) manage to 100% classify the three species and the cross validation step of the method returned 97.4% of correctly classified samples. Only one A. mellea sample overlapped on B. edulis group. When kNN was used in the same manner as LDA, the overall percent of correctly classified samples from the training step was 86.21%, while for holdout set the percent raised at 94.74%. The lowered values obtained for the training set was due to one C. cibarius sample, two B. edulis and five A. mellea, which were placed to other species. Anyway, for holdout sample set, only one sample from B. edulis was misclassified. The fuzzy c-means clustering (FCM) analysis successfully classified investigated mushroom samples according to their species, meaning that in every partition the predominant specie had the biggest DOMs, while samples belonging to other specie had lower DOMs.
