“…However, we obtained a better result against E. coli with a MIC value of 20 mg/mL. In another study by Erdo gan Eliuz [53], the antimicrobial effect of ethanolic extracts of L. edodes and A. bisporus against K. pneumoniae, S. aureus, and A. baumannii was evaluated. The author demonstrated that the extracts of L. edodes were more effective, showing MIC values ranging from 5.9 to 6.01 mg/mL, while the extracts of A. bisporus displayed MICs ranging from 7.21 to 9.54 mg/mL [53].…”

According to Taofiq et al [29], the ethanolic extracts of P. ostreatus and L. edodes were more efficient than those of A. bisporus in inhibiting the growth of MR and MS S. aureus, with MIC values of 2.5 mg/mL and 10 mg/mL, respectively.…”

Waste generated in mushroom cultivation represents a valuable raw material with health benefits, the use of which contributes to a reduction in food waste and to the circular economy. Hydroethanolic extracts obtained by ultrasound-assisted extraction of four edible mushroom species (Agaricus bisporus var. Portobello, Boletus edulis, Lentinula edodes, and Pleurotus ostreatus) were characterized according to their antioxidant, antibacterial, and cosmeceutical potential. The extract with the best properties was incorporated into a cosmetic cream. Concerning the phenolic contents and antioxidant capacity, the extracts of A. bisporus and B. edulis stood out from the other two due to their higher levels. The compounds p-hydroxybenzoic and gallic acids were present in all mushrooms in the ranges of 0.010 to 2.554 µg/g DW and 0.032 to 0.112 µg/g DW, respectively. The extract of B. edulis inhibited all the bacterial isolates, with minimum inhibitory concentration values ranging from 5 to 20 mg/mL for Gram-positive and 10–20 mg/mL for Gram-negative strains. In the anti-hyaluronidase assay, A. bisporus extract (10 mg/mL) was the most effective, with 74.4 ± 7.5% enzyme inhibition, and was selected for incorporation into the cosmetic cream. The cream with A. bisporus extract showed significantly higher phenolic contents and antioxidant capacity than the cream without the extract. Overall, our results support the high value of mushroom reuse as a source of natural antioxidants in the cosmetic industry.

“…All plates were incubated at 37 °C for 24 h and growth (turbidity) was measured at 600 nm. The substance concentration at which growth was inhibited by 99.9 % (MIC99) was calculated with the following formula (Equation 2 and 3) [35] . All experiments were performed in triplicate and each measurement was read three times and averaged.

In this study, Schiff bases were synthesized by utilizing the reaction of 4‐ and 5‐aminoindane with substituted benzaldehydes. After the reduction of isolated Schiff bases with NaBH4, the corresponding secondary amine derivatives were obtained. The structures of all synthesized molecules were confirmed by 1H‐NMR, 13C‐NMR, FTIR, and ESI‐MS. Antioxidant activities of all synthesized molecules were investigated by DPPH method, and IC50 values were calculated. In addition, antibacterial activities of targets were investigated by the well diffusion method, and then MIC99 values were calculated. While only four of the sixteen synthesized molecules showed a high level of antioxidant activity, all of the molecules exhibited biological activity against gram‐positive and gram‐negative bacteria to varying degrees. In addition, all the synthesized molecules showed high antifungal activity. In antioxidant capacity studies, the IC50 values of 2‐(((2,3‐dihydro‐1H‐inden‐5‐yl)amino)methyl)‐6‐methoxyphenol (4d) and 2‐(((2,3‐dihydro‐1H‐inden‐4‐yl)amino)methyl)‐6‐methoxyphenol (7d) were determined to be 18.1 µg and 35.1 µg, respectively, and these values are much stronger than BHT (butylated hydroxytoluene) and BHA (butylated hydroxyanisole) used as positive controls. The fact that targets have the same core structure with different substituents has revealed a good structure‐activity relationship.

Edible mushrooms are seen as a way of increasing dietary diversity and achieving food security in Ethiopia. The aim of this study was to develop substrates using locally available agro-industrial by-products and animal manures to enhance the production of Shiitake (Lentinula edodes) mushrooms in Ethiopia. The hypothesis was L. edodes mushroom production on seven different substrates: 100% sugarcane bagasse (S1), 80% sugarcane bagasse, 20% cow dung (S2), horse manure (S3), chicken manure (S4), cottonseed hulls (S5), sugarcane filter cake (S6), and sugarcane trash (S7). Mushroom yield and biological efficiency were significantly affected by substrate type (p < 0.05). A significantly higher yield (434.33 g/500 g of substrate) and biological efficiency (86.83%) were obtained using substrate S4 while lower yield (120.33 g/500 g) and biological efficiency (24.33%) were obtained using substrate S7 than when using other substrates. The largest first flush of mushrooms was obtained on S4, and five flushes were produced on this substrate. S4 also had the highest biological efficiency, the highest nitrogen content, and the lowest C:N. Chicken manure is rich in nitrogen, magnesium, calcium, and potassium, which are crucial for Shiitake mushroom growth. Thus, substrate S4 would be a viable option for cultivating Shiitake mushrooms, particularly in regions where chicken manure is readily available. Substrate S2 also provided high yields and rapid fructification and would be a suitable alternative for Shiitake mushroom cultivation.
