“…production in Egypt are chopped rice straw (Daba et al, 2008). Only a small percentage of fruit bodies sold in the Egyptian markets and they are always either Pleurotus or Agaricus mushroom (Shbeeb et al, 2019). It was reported that the maximum yield production of Pleurotus fruiting bodies were found during winter (14-27 • C, and relative humidity at 70-80%) (Uddin et al, 2010).…”

One strategy to manage resistant pathogens and develop potential anticancer drugs is the search for new, promising, and cost-effective medicinal benefits in the field of bioactive metabolites derived from mushrooms. In the current study, Egyptian cultivated Pleurotus ostreatus fruiting bodies polar extract was prepared to evaluate its antimicrobial activities as well as its cytotoxic effect on various cancer cell lines. The Pleurotus ostreatus polar extract (PoPE) was characterized by its phenolic and flavonoid content. The phenolics and flavonoids of PoPE were 6.94 and 0.15 mg/g, respectively. P. ostreatus polar extract showed potent antimicrobial activity against four pathogens, including Candida albicans, Staphylococcus aureus, Micrococcus luteus, and Escherichia coli. PoPE was found to inhibit Fusarium oxysporum (47%), Fusarium solani (28%) as well as Rhizoctonia solani (21%). PoPE was found to be 13 times more selective and toxic to MCF-7 cells than Vero normal cells, with the lowest IC50 value (4.5 μg/mL), so they were selected to examine the potential cytotoxic effects of PoPE. In MCF-7 cells, PoPE appeared to promote cell cycle arrest in the sub-G1 stage, as well as apoptosis. It significantly increased TNF-α production while decreasing IL-6 levels. PoPE’s total antioxidant capacity, lipid peroxide, and glutathione reductase activity were recorded 0.14 ± 0.02 mM/L, 15.60 ± 0.015 nmol/mL, and 9.50 ± 1.30 U/L, respectively. The existence of different bioactive metabolites was investigated via GC-MS, which confirmed the presence of 15 compounds with well-known biological activity.

“…Because of its high phenolic content, one of the most well‐known therapeutic properties of P. ostreatus is its antioxidant activity (Barbosa et al, 2020). This mushroom, which has both delicious and medicinal properties, is marketed as fresh, canned, frozen, or dried (Shbeeb et al, 2020). Dried mushrooms are used as ingredients in soups, pizzas, and ready‐to‐eat canned foods, and are also used as a mushroom powder in different food ingredients (Özünlü & Ergezer, 2021).…”

In this research, extraction parameters were optimized for the maximization of the antioxidants of mushrooms. Firstly, the total antioxidant status (TAS) and total oxidant status (TOS) of mushrooms under different extraction parameters were determined. Then, artificial neural network (ANN) and multiobjective particle swarm optimization (MOPSO) were applied for modeling and optimization of the extraction process, respectively. The three variables affecting this process were extraction temperature (40 to 70°C), extraction time (4 to 10 h), and extraction concentration (0.25 to 2 mg/ml). The developed ANN‐based model could predict with a correlation coefficient of 0.986 and 0.991 for TAS and TOS values, respectively. The optimum extraction parameters were extraction temperature of 40.721°C, extraction time of 6.267 h, and extraction concentration of 2 mg/ml. These results indicated that the ANN‐MOPSO hybrid model provides an accurate prediction and optimization method for TAS and TOS values of Pleurotus ostreatus extracts. Novelty impact statement This research has three stages: experimental study, modeling, and optimization. Artificial neural network (ANN) was used for modeling stage and multiobjective particle swarm optimization algorithm (MOPSO) was used for the optimization process. It is the first time two methodologies have been combined for Pleurotus ostreatus extraction optimization. ANN‐MOPSO hybrid model can be used to optimize mushroom extraction to save time, labor, and money.

“…Demand for edible mushrooms has elevated due to their taste and nutrient content (5,6). Mushrooms are preferred over animal proteins, and this fact has been supported by various studies (5,(7)(8)(9). Several types of vitamins in mushrooms are responsible for improving human health by decreasing the risk of various diseases (10).…”

Background: The growing population and limited agricultural land have pushed the demand for higher food production per land area. Edible mushrooms are a rich source of protein. Agaricus bisporus is the most common edible mushroom with high economic value. One of the most important steps in the production process of white button mushroom is the production of spawn. It is highly important to make pure high-quality mycelium during the production of spawn. Studies have shown that at this stage of production, a high level of morphological changes occurs in some mushrooms, which causes the formation of fluffy-shaped mycelium. This phenomenon is a kind of strain degeneration in edible mushrooms and is one of the biggest concerns of the producers of white button mushroom. Objectives: The purpose of this study was to investigate the nature of stroma (strain degeneration) in white button mushroom, and to identify the causes of genetic changes. Methods: In this experiment, ten successive subcultures were produced from the mother mycelium on potato dextrose agar medium (pH: 6.2), and the genetic changes of mycelium were examined after ten successive subcultures. DNA extraction was performed after sampling of the mother, normal, and fluffy mycelia. Six pairs of designed primers and propagated parts were loaded into six polyacrylamide gels. DNA fragments were visualized using silver staining. Genetic comparisons were made between the mother, normal, and fluffy mycelia by the amplified fragment length polymorphism (AFLP) method, and the results were evaluated using POPGENE software. Results: The AFLP marker produced 137 fragments for the H2 strain, of which 57 fragments had polymorphism between the mother, normal, and fluffy mycelia. For the 737 strain, 149 fragments were produced, of which 73 fragments had polymorphism between the mother, normal, and fluffy mycelia. On average, the mother, normal, and fluffy mycelia had about 42 and 49% polymorphism for the H2 and 737 strains, respectively. The degree of polymorphism among the samples confirmed genetic differences between the mother, normal, and fluffy mycelia. Conclusions: Based on the results of the present study, we concluded that strain degeneration, which manifests as the fluffy mycelium of white button mushroom, has a genetic origin. These genetic differences can be attributed to diverse factors, such as the phenomenon of heterokaryosis, asexual recombination, and the formation of mitosis crossing over. These factors and their effects require further evaluations.
