“…The integration of mushroom production and agro-based wastewaters as a nutrient supply constitutes a sustainable and effective way for the treatment of the latter [42]. Moreover, the use of nutritional supplements in mushroom cultivation can provide the fungi with readily available nitrogen and carbon, thus promoting an earlier and larger mushroom production [35,43]. A few research works have reported the use of SMW as a substrate supplement in mushroom cultivation.…”

This study investigates the sustainable production of Shiitake (Lentinula edodes) mushroom using agro-industrial wastes. The substrate of Shiitake (80% rice straw + 20% sugar cane bagasse) was moistened with 0 (freshwater as control), 50, and 100% concentrations of secondarily treated dairy plant and sugar mill wastewaters (DPW and SMW). After proper sterilization, the cultivation was carried out under controlled environmental conditions using the bag log method for 100 days. The results revealed that DPW and SMW moistening significantly (p < 0.05) increased the nutrient levels of the formulated substrate which later gave better mushroom yield. The highest Shiitake mycelial coverage (90.70 ± 1.47 and 88.65 ± 1.82%), yield (186.00 ± 3.10 and 176.09 ± 4.12 g/kg fresh substrate), biological efficiency (80.00 ± 0.58 and 75.73 ± 0.93%), total phenol (2.84 ± 0.03 and 2.69 ± 0.03 mg/g), ascorbic acid (0.34 ± 0.03 and 0.32 ± 0.02 mg/g), and β-carotene (2.48 ± 0.06 and 2.29 ± 0.02 μg/g) contents with the minimum time taken for spawn running (60 ± 1 days) was observed using a 50% concentration treatment of both DPW and SMW, respectively. Besides this, the kinetic studies using a first-order-based model showed acceptable accuracy in predicting the rate constant for substrate delignification and heavy metal uptake by Shiitake mushroom. These findings suggest a novel approach for sustainable mushroom cultivation using agro-industrial wastes. The concept can be used for the production of high-quality mushrooms for edible and medicinal purposes while contributing toward the United Nations’ Sustainable Development Goals (SDGs 12) on responsible consumption and production of superfoods.

“…The nutritional quality of commercially produced mushrooms is strongly determined by the chemical composition of the growing substrate [8][9][10][11][12][13][14][15] and the type of supplements added to them [12,14]. Agaricus bisporus, commonly known as the white button mushroom, is cultivated on a fermented substrate composed of a mixture of lignocellulosic materials, mainly horse and chicken manure [8,16,17].…”

The present study focused on the use of sewage sludge (SS) as a casing material amendment and the potential uptake of metal elements by the cultivated white button (Agaricus bisporus: MS-39) mushroom. Laboratory experiments were performed under controlled environmental conditions to grow A. bisporus on the composted wheat straw substrate for 50 days. Different treatments (0, 50, 100, 150, and 200 g/kg) of casing material were prepared by mixing garden and dried SS and applied on the mushroom substrate after proper sterilization. The results revealed that SS application was significant (p < 0.05) in accelerating mushroom yield with a biological efficiency of 65.02% for the mixing rate of 200 g/kg. Moreover, the maximum bioaccumulation of selected metal elements (Cu, Cr, Cd, Fe, Mn, and Zn) was observed using the same treatment. Additionally, the multiple regression models constructed for the uptake prediction of metal elements showed an acceptable coefficient of determination (R2 > 0.9900), high model efficiency (ME > 0.98), and low root mean square error (RMSE < 0.410) values, respectively. The findings of this study represent sustainable use of SS for the formulation of mushroom casing material contributing toward synergistic agro-economy generation and waste management.

“…It is ranked as the second most cultivated mushroom in the world [8] and is well known for its high nutritional value (carbohydrates, protein, minerals) and medicinal properties (vitamins and antioxidants) [9]. It is mainly grown on wheat straw substrate [10,11] beside many other substitutes like spent mushroom substrate (SMS) [12,13], spent coffee grounds [14], maize wastewater [15], tea leaves [16] and so on. It is noteworthy that the type of substrate affects majorly the yield and composition of produced mushrooms [17,18].…”

The exponential disposal of agro-industrial wastes onto the environment has endangered all forms of life. The implementation of these wastes in mushroom production is an eco-friendly and promising solution. The effect of olive and tea leaves extracts represented in culture media treatments: potato dextrose agar (PDA) 80% + tea extract (TE) 20% (T2), PDA 80% + olive extract (OE) 20% (T3), PDA 80% + OE 10% + TE 10% (T4), PDA 70% + OE 20% + TE 10% (T5) on mycelial growth diameter (MGD) and linear growth rate (MLGR) of Pleurotus ostreatus var. florida was compared to the one of PDA used as control (T1) at 22, 25 and 28°C inoculation temperatures. Optimum MGD was observed at 28°C in T1 (day 2), while it was significantly increased by 1.1–1.4 folds (days 4, 6, 8) in culture media containing plant extracts nevertheless the inoculation temperature. MLGR was improved by 102%–145% in olive/tea culture media compared to PDA nevertheless the inoculation temperature. Optimum growth induction index (GII) was observed in T3 (22.2%) at 22°C, T5 (21.9%) at 25°C and T4 (18.2%) at 28°C. These findings suggest the combination of olive and tea leaves extracts in the production of Pleurotus ostreatus.
