Antibacterial activity of Pleurotus species
2013
Basidiomycetes express promising antitumor, immune modulating, cardiovascular and hypercholesterolemia, antiviral, antibacterial and antiparasitic effects (Wasser & Weis, 1999; Reshetnikov et al., 2001; Wasser, 2002, Didukh et al., 2003). They are also well known for their safety and efficacy as functional foods and dietary supplements (Wasser & Akavia, 2008). The antibacterial and antiviral value of different genera of Basidiomycetes has been tested by different authors (Benedict & Brady, 1972; Donnelly et al., 1986; Gao et al., 2003;). In particular the antibacterial and antiparasitic therapeutic effects were investigated in the genera Flammulina P. Karst, Fomes (Fr.) Fr., Ganoderma P. Ka…
A reappraisal of the Pleurotus eryngii complex – New species and taxonomic combinations based on the application of a polyphasic approach, and an ide…
2014
The Pleurotus eryngii species-complex comprises choice edible mushrooms growing on roots and lower stem residues of Apiaceae (umbellifers) plants. Material deriving from extensive sampling was studied by mating compatibility, morphological and ecological criteria, and through analysis of ITS1-5.8S-ITS2 and IGS1 rRNA sequences. Results revealed that P. eryngii sensu stricto forms a diverse and widely distributed aggregate composed of varieties elaeoselini, eryngii, ferulae, thapsiae, and tingitanus. Pleurotus eryngii subsp. tuoliensis comb. nov. is a phylogenetically sister group to the former growing only on various Ferula species in Asia. The existence of Pleurotus nebrodensis outside of S…
Taxonomic Identity, Geographic Distribution, and Commercial Exploitation of the Culinary-Medicinal Mushroom Pleurotus nebrodensis (Basidiomycetes)
2016
An updated overview of the outcome of studies conducted on the culinary-medicinal mushroom Pleurotus nebrodensis is presented by placing emphasis on the clarification of the taxonomic identity of P. nebrodensis and other related taxa possessing entirely white to cream basidiomes, which grow in association with different plants of the family Apiaceae. Cultivation techniques, quality of the product sold and sales price, as well as nutritional and medicinal aspects are discussed. Taking also into consideration the high economic importance of P. nebrodensis, it is essential to proceed with the verification of the commercial strains currently available in the international market under the name …
Medicinal Properties of Mediterranean Oyster Mushrooms: Species of Genus Pleurotus (Higher Basidiomycetes)
2017
The term “Mediterranean area,” applied in this chapter, refers to the definition reported in Med-Checklist and particularly to all countries bordering the Mediterranean Sea plus Portugal, Bulgaria, the Crimea (Ukraine), and Jordan. The “Mediterranean oyster mushrooms” is a geographically and ecologically well-defined group of Basidiomycetes. The medicinal properties of some widely investigated species such as Pleurotus ostreatus and P. eryngii are recognized worldwide, while in the case of some other Mediterranean Pleurotus taxa, there is still a lack of knowledge. A substantial increase in knowledge about the anticancer and antibacterial properties of the group of Pleurotus species growing…
Functional bread supplemented with Pleurotus eryngii powder: A potential new food for human health
2022
The purpose of this study was to develop functional breads with powdered Pleurotus eryngii. The breads were produced applying the traditional Italian style sourdough technology. P. eryngii powder was added to flour of tender wheat varieties (Grano Dei Miracoli, Inalettabile, Mentana, Gentilrosso, Ardito and a mix of Rieti, Verna, and Mentana) or semolina of durum wheat landrace (Saragolla) and subjected to sourdough fermentation. Sourdough inoculum was produced with selected strains of lactic acid bacteria (LAB) belonging to the species Levilactobacillus brevis, Weissella cibaria and Leuconostoc citreum. The addition of Pleurotus powdered (PP) (10% w/w) did not influence the fermentation pr…
Ethnobotany of the Aegadian Islands: safeguarding biocultural refugia in the Mediterranean
2021
Abstract Background The Aegadian Islands are located west of Trapani, Sicily. Once the site of bountiful tuna fisheries and fruit orchards (plums, peaches, apricots), grapevines, prickly pears, and grains, the local economy is now based on tourism, and many traditional agricultural and maritime practices have been abandoned. In this study, we aimed to evaluate the state of traditional ecological knowledge (TEK) concerning the use of wild and cultivated plants and fungi for human health, food, maritime, and agricultural purposes on the islands of Levanzo, Favignana, and Marettimo and compare present-day practices with those documented in the past. Methods In-depth semi-structured interviews …
The cultivation of Pleurotus and Lentinus mushrooms in tropical and subtropical areas: an overview
2010
The cultivation of edible mushrooms dates back a long time (CHANG & QUIMIO, 1982). The oyster mushrooms [Pleurotus (Fr.) P. Kumm.] are among the most popular edible mushrooms, and their cultivation is practiced throughout the world (KONG, 2004). P. ostreatus (Jacq.) P. Kumm. is the most widely-cultivated Pleurotus species for which many commercial strains have been developed. Other Pleurotus spp., i.e. P. cystidiosus O.K. Mill., P. djamor (Rumph. ex Fr.) Boedijn and P. pulmomarius (Fr.) Quél., are also exploited in both tropical and subtropical regions. In addition, Lentinus tuber-regium (Fr.) Fr., a common mushroom species in the southern part of Nigeria, is being studied and cultivated fo…
In vitro antitumor effects of the cold-water extracts of Mediterranean species of genus Pleurotus (higher Basidiomycetes) on human colon cancer cells
2014
The aim of this study was to evaluate whether the cold-water extracts of Pleurotus eryngii var. ferulae (CWE-Pef) and Pleurotus nebrodensis (CWE-Pn), 2 of the most prized wild and cultivated edible mushrooms, can affect the tumor phenotype of human colon cancer HCT116 cells. Our results showed that treatment with CWE- Pef and CWE-Pn resulted in a significant inhibition of the viability of HCT116 cells and promoted apoptosis, as also demonstrated by the increase of Bax-to-Bcl-2 messenger RNA ratio. Moreover, we observed that both extracts were able to inhibit cell migration and to affect homotypic and heterotypic cell-cell adhesion. It also was found that treatment with CWE-Pef and CWE-Pn ne…
Pleurotus eryngii var. thapsiae var. nov. from Sicily
2002
Field investigation in the Sicilian territory allowed the study of Pleurotus eryngii basidiomata growing in association with Thapsia garganica. The evaluation of morphological, ecological, distribution and isozyme, and PCR-RAPD data together with a revision of Bresadola's herbarium specimens kept in the Herbarium Botanische Staatssamlung (M) led to the description of a new variety, Pleurotus eryngii var. tahpsiae var. nov.
In vitro antitumor effects of the cold-water extracts of Pleurotus eryngii var ferulae and Pleurotus nebrodensis on human colon cancer cells
2013
For centuries, mushrooms have been used as folk medicines especially in Asian countries where their medicinal properties are well known. On the basis of numerous experimental evidences collected in the last decades, the immunomodulatory and anti-neoplastic properties of substances extracted from various species belonging to genera of edible mushrooms [Agaricus L., Auricularia Bull. ex Juss., Ganoderma P. Karst., Grifola Gray, Lentinus Fr., Schizophyllum Fr., Tremella Dill ex L., etc.] are extensively recognized also at scientific levels. Several works have demonstrate that anti-cancer property of these molecules is due to their ability to enhance immune system activity and/or to act directl…
