Rice straw (RS) collected from Egyptian agricultural environment (Al-Masied village-Alsharqia Governorate-Egypt) was used as substrate for three fungal isolates namely: 4b, 1Asp, Pleurotus ostreatus NRRL 3501 and mixed culture of (4b, 1Asp). Isolates number 4b and 1Asp were identified using the molecular technique (18S rRNA). Isolate 4b and 1Asp, were identified as Trichoderma saturnisporum MN1-EGY and Aspergillus niger MN2-EGY, respectively. Trichoderma saturnisporum MN1-EGY extract exhibited the highest antimicrobial activity compared to the other fungal extracts. Total phenolic, antimicrobial and antioxidant activities were also determined from the ethyl acetate extract of rice straw inoculated by these fungi. The antioxidant scavenging concentration(SC50) values of the tested samples were 88.84, 91.45, 94.65 and 100.0µg/ml, respectively for Pleurotus sp., Aspergiluus niger, Aspergiluus niger + Trichoderma sp., and Trichoderma sp., after 15 days incubation, compared to ascorbic acid as positive control with SC50 value equal to 8.0 µg/ml. Total phenolic contents (TPCs) were maximum in Pleurotus sp. extract and found to be the most polyphenolic enriched sample (380.64 mg GAE/g dry extract) compared to extracts of Aspergiluusniger, Aspergiluus niger + Trichoderma sp., and Trichoderma sp. (261.89, 198.52, and 119.80 mg GAE/g dry extract), respectively. The GC-MS analysis has been also performed for the promising extracts.

“…p-Hydroxybenzoic, p-coumaric and cinnamic acids were identified in the extract at the following concentrations, respectively: 66 ± 4, 43.7 ± 0.9 and 37.5 ± 0.3 µg/g extract (Table A2). The presence of these compounds was reported in many other mushrooms species (Nattoh, Musieba, Gatebe, & Mathara, 2016). However, according to Carrasco-González, Serna-Saldívar, and Gutiérrez-Uribe (2017), mushrooms' chemical composition varies drastically with the substrate where they grow.…”

A B S T R A C TA study with Pleurotus sajor-caju was conducted to: evaluate the nutritional and chemical composition of the fruiting bodies; optimize the preparation of bioactive phenolic extracts; and characterize the optimized extract in terms of bioactive compounds and properties. P. sajor-caju revealed an equilibrated nutritional composition with the presence of hydrophilic (sugars and organic acids) and lipophilic (tocopherols and PUFA) compounds. pHydroxybenzoic, p-coumaric and cinnamic acids were identified in the extract obtained with ethanol (30 g/l ratio) at 55°C for 85 min. This extract showed antioxidant properties (mainly reducing power and lipid peroxidation inhibition), antibacterial activity against MRSA and MSSA and cytotoxicity against NCI-H460, MCF-7 and HeLa. Furthermore, as the extract showed capacity to inhibit NO production in Raw 264.7 macrophages, molecular docking studies were performed to provide insights into the anti-inflammatory mechanism of action, through COX-2 inhibition by the phenolic acids identified.

“…At 4 mg/mL, A. auricula had a reducing power of 0.403 nm, the results indicate that A. auricula has a greater potential for hydrogen donation, implying that it possesses significant reducing power (Packialakshmi et al, 2017). Nattoh et al (2016) examined reducing power assay on four different parts of the body of Pleurotus djamor, those being spawn mycelia phase, early young fruiting body, young fruiting body, and mature fruiting body. Results showed the ethanolic extract of young fruit body yield at 5 mg/ mL concentration had the highest (11.491) reducing power activity, higher than water extract of young fruit body of P. djamor (10.077).…”

Pleurotus spp. and Auricularia spp. are popular species consumed by the Malaysian community. Recently, due to increased awareness, both mushrooms are also being consumed for their bioactive compounds, ergothioneine, and antioxidant properties and has been used since earlier ages as therapeutic remedies. The bioactive compounds such as phenol, flavonoid and ergothioneine found in both Pleurotus and Auricularia mushrooms were explored. Differences in heat treatments (microwave, hot air drying, and solar drying) and cooking methods may affect the content of bioactive compounds and their properties. Similarly, sensory acceptance by consumers may be affected too. Antioxidant properties using DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical and FRAP (ferric reducing antioxidant power) assay of both raw and heat-treated mushrooms are included. Microwave drying retained color characteristics and bioactive compounds in both mushrooms. To add value to this review, a survey on the consumption pattern of Pleurotus and Auricularia species among Malaysians has been conducted online and concluded that Pleurotus species is the most considered species compared to Auricularia mushroom and almost half of the respondents were not aware that heat may deplete nutritional contents in mushroom despite agreeing both gave beneficial health in diets.
