Ganoderma lucidum (Curt.: Fr.) Karst. – health-promoting properties. A review
2015
Summary This paper presents the characteristics of the species Ganoderma lucidum in terms of health-promoting properties. This species is rare in Poland, and is subject to strict protection. Reishi is classified as a medicinal mushroom which fruiting bodies are characterized by a content of active substances with diverse positive effects on human health. G. lucidum is particularly rich source of bioactive compounds, which are obtained from fruiting bodies, mycelium and spores of this species. The therapeutic effect of G. lucidum extracts has been demonstrated in many scientific studies. The most important pharmacological and physiological effects include: immunomodulatory, anti-cancer, anti…
Biokumulacja pierwiastków w grzybach wielkoowocnikowych - przegląd wybranej literatury
2017
Celem pracy było dokonanie analizy bibliometrycznej wybranych publikacji dotyczących akumulacji pierwiastków w grzybach wielkoowocnikowych (ektomikoryzowych i saprofitycznych) występujących na terenie Europy. Analizie poddano wybrane publikacje z lat 2001-2016 dostępne poprzez serwisy, np.: Springer, Science Direct i Web of Science. Przeanalizowano m.in. akumulowane mikro- i makropierwiastki, miejsca prowadzenia badań oraz typ badań (m.in. badania in situ, badania laboratoryjne). W wyniku przeprowadzonych badań literaturowych stwierdzono, że temat translokacji pierwiastków do grzybów wielkoowocnikowych jest nadal aktualny i cieszy się dużym zainteresowaniem naukowców z wielu krajów europejs…
Pholiotina cyanopus, a rare fungus producing psychoactive tryptamines
2014
Abstract Pholiotina cyanopus was collected from wood chips and other woody remnants of undetermined tree species. Its basidiomata were found in June within the area of closed sawmill in the central part of Żywiec city (SW Poland). Description and illustration of Ph. cyanopus based on Polish specimens are provided and its ecology, general distribution and comparison with similar taxa – Pholiotina smithii, Pholiotina sulcatipes, and others are discussed as well. The identity of the active compounds of Ph. cyanopus was additionally determined. Liquid chromatography–mass spectrometry (LC-MS) data sets were obtained to support the occurrence of psilocybin and its analogues – psilocin, baeocystin…
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…
Ferdinands Erdmanis Štolls. Sēņu pasaule
2023
“Muzeja sērijas” trešā grāmata “Ferdinands Erdmanis Štolls. Sēņu pasaule.” Tā ir neliels ieskats mikologa F. E. Štolla (Ferdinand. Erdman Stoll; 1874–1966) vairāk kā 1000 lapu lielajā sēņu attēlu kolekcijā, ko zinātnieks ir izveidojis pētot Latvijas sēnes un, kas pamatā sastāv no paša pētnieka zīmētajiem akvareļiem. Akvareļu kolekcija ir viens no Latvijas Universitātes Muzeja Botānikas un mikoloģijas kolekciju dārgumiem, kas joprojām ir ne tikai pētnieku interešu objekts, bet spēj iepriecināt jebkuru interesentu ar savām estētiskajām kvalitātēm. Publicētos akvareļus raksturo citāti no 1934. gadā izdotās F. E. Štolla grāmatas “Latvijas sēnes”, kas ir pirmā izdotā mikoloģijas grāmata latviešu…

Quantification of Platinum in Edible Mushrooms Using Voltammetric Techniques
2021
Edible mushrooms are a food source with interesting nutritional values. The chief objective of this research was to develop a consistent method for the quantitative ultra-trace analysis of Pt in mushrooms, which is complex because it cannot be readily quantified by common analytical procedures. This research is one of the first analytical methods to establish Pt amount in these vegetables. In this research, 28 different edible mushroom samples from Italy were investigated. Determination of Pt in mushrooms was completed using Differential Pulse Voltammetry (DPV). In this study, we applied the standard addition method because there are no certified reference mushrooms containing platinum grou…
