“…They were identified by comparing their morphological characters against related literature [5]. Mushroom extraction was carried out using chloroform, 70% ethanol, and hot water solvents [6, 7]. A 100 g of powdered mushroom was mixed with 0.5 L of each solvent in a conical flask at 25°C and was shaken using an incubator shaker at 150 rpm for 72 h. The extracts were centrifuged at 3000 rpm for 15 min, filtered with Whatman No.1 filter paper, and evaporated and dried using a rotary evaporator at 50°C.…”

“…These bioactive compounds are found in various cellular components and secondary metabolites, which have been isolated and identified from the fruiting bodies [6]. The fruiting bodies and mycelium of mushrooms exhibit health promoting values such as immunostimulatory, antibacterial, and antioxidative properties [7]. The synergistic effect of these substances would give potential therapeutic values.…”

Objective. This study has investigated the antimicrobial activity of extracts of indigenous wild mushrooms against selected organisms. Methods. Thirty-five (35) indigenous wild mushrooms were collected from Arabuko-Sokoke and Kakamega National Reserve Forests, Kenya. All mushrooms were identified and their contents were extracted and screened for their antimicrobial activities against Escherichia coli (clinical isolate), Klebsiella pneumoniae (ATCC 13883), Pseudomonas aeruginosa (clinical isolate), Pseudomonas aeruginosa (ATCC 27853), Staphylococcus aureus (ATCC 25923), MRSA (ATCC 33591), Candida albicans (clinical isolate), and Candida parapsilosis (ATCC 90018) using tetrazolium microtiter plate bioassay method. Results. Of the 35 tested mushroom extracts, extracts of three (3) mushrooms, namely, Trametes spp. (Arabuko-Sokoke forest), Trametes, and Microporus spp. (Kakamega forest), have shown promising antimicrobial activities against the tested organisms. The S. aureus (ATCC 25923), P. aeruginosa (ATCC 27853), and Methicillin-Resistant Staphylococcus aureus (MRSA) (ATCC 33591) were the most susceptible to chloroform extract of Trametes spp. collected from Arabuko-Sokoke forest. Of the tested organisms, S. aureus (ATCC 25923) was the most susceptible whereas E. coli was the most resistant organism to the hot water extract of Trametes spp. collected from Arabuko-Sokoke forest. Chloroform extract of Microporus spp. has shown the highest antibacterial activity against S. aureus (ATCC 25923), MRSA (ATCC 33591), and K. pneumoniae (ATCC 13883) but limited activity against E.coli. All extracts of the three wild mushrooms have shown the most antibacterial activities against S. aureus (ATCC 25923). Conclusion. The present study has shown that the extracts of the three wild mushrooms have shown promising antimicrobial activities against the tested organisms.

“…Twenty-six species, including Pleurotus eryngii (PE), Pleurotus citrinopileatus (PC), Pleurotus flabellatus (PFL), Pleurotus ostreatus (PO), Pleurotus djamor var. roseus (PDR), and Pleurotus florida (PF), have been reported to be cultivated using different types of lignocellulosic wastes [3][4][5][6][7][8][9][10][11]. A large number of Pleurotus species were identified and commercialized.…”

Cultivation and Nutritional Value of Prominent Pleurotus spp.: An Overview

et al. 2020

View full text Add to dashboard Cite

Pleurotus species are commercially essential mushrooms and widely cultivated throughout the world. The production of Pleurotus mushrooms alone accounts for around 25% of that total cultivated mushrooms globally. In America and Europe, Pleurotus species are considered specialty mushrooms, whereas, in Korea, their cultivation is economically profitable, and it is one of the highly consumed species. Pleurotus species are predominantly found in tropical forests and often grow on fallen branches, dead and decaying tree stumps, and wet logs. Biographical studies have shown that the Pleurotus genus is among the more conspicuous fungi that induce wood decay in terrestrial ecosystems worldwide due to its formidable lignin-modifying enzymes, including laccase and versatile peroxidases. Pleurotus species can be grown easily due to their fast colonization nature on diversified agro-substrates and their biological efficiency 100%. Pleurotus mushrooms are rich in proteins, dietary fiber, essential amino acids, carbohydrates, water-soluble vitamins, and minerals. These mushrooms are abundant in functional bioactive molecules, though to influence health. Pleurotus mushrooms are finding unique applications as flavoring, aroma, and excellent preservation quality. Apart from its unique applications, Pleurotus mushrooms have a unique status delicacy with high nutritional and medicinal values. The present review provides an insight into the cultivation of Pleurotus spp. using different agro-waste as growth substances paying attention to their effects on the growth and chemical composition.

“…Pleurotus eryngii is a significant source of lovastatin, also known as monocline k, which is a naturally occurring compound, and the hypolipidemic agent acts through the inhibition of the HMG-CoA reductase [22]. Lovastatin not only reduces blood cholesterol, but it also has anti-inflammatory, anticoagulation, antioxidative, anti-fungal, and anti-carcinogenic effects [23,24]. Acidic and alkalic-extractable zinc polysaccharides extracted from P. eryngii mycelia have demonstrated hepatoprotective and antioxidant effects [25].…”

Selenium and Zinc Biofortification of Pleurotus eryngii Mycelium and Fruiting Bodies as a Tool for Controlling Their Biological Activity

et al. 2020

Pleurotus eryngii (DC:Fr.) Quel. is a cultivated mushroom of high culinary value and medicinal properties. Mycelium of P. eryngii is characterized by the ability of effective bio-elements absorption from growth media so it could be biofortified with trace elements with a functional activity in the human body. In this study, the ability of P. eryngii mycelia from in vitro cultures as well as fruiting bodies were investigated in terms of their effectiveness in zinc and selenium accumulation. The effect of Se and Zn biofortification on productivity, chemical compounds, and bio-elements content of P. eryngii was determined as well. To enhance Se and Zn content in P. eryngii fruiting bodies and mycelia, substrates were supplemented with sodium selenite, at a concentration of 50 mg L−1, zinc sulfate, and zinc hydro-aspartate at a concentration of 87.2 and 100.0 mg L−1, respectively. Mentioned Zn concentrations contained the same amount of zinc(II) ions, namely 20 mg L−1. The content of organic compounds include phenolic compounds and lovastatin, which were determined by a high-performance liquid chromatography with diode-array detector (HPLC-DAD) and reverse phase high-performance liquid chromatography (RP-HPLC) method with UV detection. The ability of P. eryngii to accumulate zinc and selenium from the culture medium was demonstrated. The degree of accumulation of zinc turned out to be different depending on the type of salt used. The present study also showed that conducting mycelium of P. eryngii in in vitro culture, with a higher content of zinc ions, can result in obtaining the materials with better antioxidant ability. The results of this study can be used to develop the composition of growing media, which ensures the production of biomass with the desired composition of elements.
