Pleurotus opuntiae revisited e An insight to the phylogeny of dimitic Pleurotus species with emphasis on the P. djamor complex
2018
Abstract The name Pleurotus opuntiae is indiscriminately used for describing mushrooms with white to off-white to white-grey pilei with short or absent stipe and dimitic hyphal system, which grow on plants of the genera Opuntia, Yucca, Agave, Phytolacca etc. However, the outcome of the present study evidences that this name should be reserved for specimens deriving from the Mediterranean area only; an epitype originating from Italy on Opuntia ficus-indica is designated. Pertinent material was sequenced by using the internal transcribed spacer region (ITS) and found to be phylogenetically related to P. djamor from Kenya and Nigeria, while members of the P. djamor complex from other continent…
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 …
JNK pathway and heat shock response mediate the survival of C26 colon carcinoma bearing mice fed with the mushroom Pleurotus eryngii var. eryngii wit…
2021
In the last few years, there has been emerging interest in developing treatments against human diseases using natural bioactive content. Here, the powder of the edible mushroom Pleurotus eryngii var. eryngii was mixed with the normal diet of mice bearing C26 colon carcinoma. Interestingly, it was evidenced by a significant increase in the survival rate of C26 tumor-bearing mice accompanied by a significant increase in Hsp90 and Hsp27 protein levels in the tumors. These data were paralleled by a decrease in Hsp60 levels. The mushroom introduced in the diet induced the inhibition of the transcription of the pro-inflammatory cytokines IL-6 and IL-1 exerting an anti-inflammatory action. The eff…
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…
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 …
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…
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…
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…
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.
The nutritional and medicinal value of Pleurotus species from Italy
2015
The genus Pleurotus is a cosmopolitan group of fungi which comprises ca. 30 species and subspecific taxa. The genus Pleurotus also represents the second main group of cultivated edible mushrooms in the world. The Pleurotus species are efficient colonizers and bioconverters of lignocellulosic agro‐industrial residues into palatable human food with medicinal properties. Besides Pleurotus species demonstrates significant nutritional and their bioactive compounds (mainly polysaccharides) possess antibacterial, antibiotic, antitumor, hypocholesterolemic and immunomodulation properties. Extracts of the Mediterranean culinary‐medicinal Oyster mushrooms P. eryngii var. eryngii, P. eryngii var. feru…
