“…[5] We have recently reported the bioconversion of sisal agro-industrial waste into high protein oyster mushrooms. [9] Nevertheless, little in known regarding the chemical composition of secondary bioactive compounds produced by Pleurotus species growing in different substrates. The chemical profile of Pleurotus ostreatus grown on sugar cane tops and sugar cane bagasse with wheat bran supplements was assessed by gas chromatography-mass spectrometry (GC/MS) and it revealed differences that reflected on the antioxidant and antimicrobial activity of the extracts.…”

“…Both cultures were grown in a potato‐dextrose‐agar (PDA) medium in Petri dishes and incubated at 25 °C in the dark for seven days. The inoculum was prepared with Sorghum bicolor grains, as described by Oliveira do Carmo, Mota da Silva, de Souza Rodrigues and Fermino Soares [9] . Three biological replication of each treatment was used in this study.…”

Pleurotus ostreatus is an edible fungus with high nutritional value that uses industrial and agricultural lignocellulosic residues as substrates for growth and reproduction. Understanding their growth metabolic dynamics on agro‐industrial wastes would help to develop economically viable and eco‐friendly biotechnological strategies for food production. Thus, we used UHPLC/MS/MS and GNPS as an innovative approach to investigate the chemical composition of two strains of P. ostreatus, coded as BH (Black Hirataki) and WH (White Hirataki), grown on sisal waste mixture (SW) supplemented with 20 % cocoa almond tegument (CAT) or 20 % of wheat bran (WB). Metabolite dereplication allowed the identification of 53 metabolites, which included glycerophospholipids, fatty acids, monoacylglycerols, steroids, carbohydrates, amino acids, and flavonoids. This is the first report of the identification of these compounds in P. ostreatus, except for the steroid ergosterol. Most of the metabolites described in this work possess potential biological activities, which support the nutraceutical properties of P. ostreatus. Thus, the results of this study provide essential leads to the understanding of white‐rot fungi chemical plasticity aiming at developing alternative biotechnologies strategies for waste recycling.

“…Crude protein is a general term for protein and nitrogen-containing compounds. Edible fungi contain more protein, with the protein content of fruit bodies accounting for 3–4% of fresh weight or 10–40% of dry weight, between meat and vegetables, and 3–6 times of common vegetables ( Oliveira do Carmo et al, 2021 ). Different treatments had certain effects on the crude protein content of fruiting bodies, and the crude protein content of all treatments except B5 was significantly different from that of the control.…”

The cultivation of Pleurotus eryngii was studied by different methods, such as puncturing and fixed-point mushroom production, shading treatment at the top of the bag, and pulling the top of the bag. The agronomic characters, yield, nutritional components, and antioxidant activities in vitro of fruiting bodies of P. eryngii were determined. The results showed that the number of buds in the perforated treatment was less than that in the production method of traditional fruiting bodies to a certain extent. When a circular hole with a diameter of 1.5 cm was drilled in the perforated treatment, the number of buds was 5, which was less than that in the control group. The efficiency of artificial removal of buds was significantly higher than that of the control group, but the harvesting date was longer than that of other methods. The number of buds in shading treatment and bag opening treatment was significantly less than that in the control group, which could effectively control the number of buds and reduce the cost of manpower and material resources. In terms of nutritional components, the A3 treatment group with a hole diameter of 1.0 cm and a quantity of one had the highest crude protein content of 151.34 g, and a significant difference was observed in crude fiber content compared with other treatments. The extraction rate of B5 crude polysaccharide was the highest, and the extraction rate was 12.90%. The antioxidant activities in vitro increased with the increase of crude polysaccharide concentration. Using A3 treatment to cultivate fruiting bodies is conducive to meeting people’s requirements for improving quality of life.

“…Thus, some agricultural waste was utilized as mushroom cultivation substrate instead of extracting bioactive compounds, such as rice straw, sugarcane, cotton seed, and wood sawdust. These wastes contain EM within that can help breakdown substrates and provide nutrient for mushroom mycelium to absorb (Sardar et al, 2017), which provides high content of vitamins, proteins, calcium, iron, and potassium for mushroom fruiting bodies (Oliveira do Carmo et al, 2021). Hence the reason for Pleurotus ostreatus to be considered as a functional and nutritional food Krakowska et al, 2020).…”

The mushroom cultivation industry in Malaysia is one of the fastest growing agricultural sectors due to its high return value and low production cost. With the Malaysian government forecasting an RM300 million worth of mushroom exporting by 2020, demand for high-quality mushrooms would rise. Commercially grown mushrooms in Malaysia include Pleurotus ostreatus, Pleurotus djamor, Pleurotus eryngii, and Schizophyllum commune. The mushroom cultivating technique is critical to achieving large yields. More mushrooms can be harvested in less time by employing Effective Microbes (EM) as a yield performance booster. However, EM is not yet commercially accessible, despite the fact that numerous potential EM exist, including dominant bacteria from mushroom production, bacteria bioinoculant, and anti-listerial agent. Furthermore, the EM activator found inside the substrate represents another yet-to-be-commercialized yield performance booster. Several possible EM activators, including as dairy wastewater, rice husk biochar, and tea compost, can be transformed from industrial waste with a steady increase in industrial waste. This paper reviewed the potential of EM in the mushroom cultivation industry. Additionally, the potential EM activator and how it enhances the mushroom yield performance is as well summarized.
