A mass spectrometric study of ions extracted from DC positive corona discharges in ambient air has been carried out within the pressure range 2.5 kPa–20 kPa. The multicomponent character spectra was confirmed. dominant series observed were type [H3O]+(H2O)n especially low current regime. In high regime, or 'streamer' regime discharge, atomic nitrogen and oxygen also discovered, but intensities these relatively comparison with peaks correpsonding to molecular ions. new mechanism responsible...

The purpose of the research was to examine decomposition rate beech (Fagus sylvatica) and aspen (Populus tremula) logs after an oyster mushroom (Pleurotus ostreatus) infection as well effect fruit body formation on chemical composition wood. highest mean value biological efficiency (B.E.) found (29.05%), but relatively high values B.E. were recorded also (21.69%). average content N about 37% higher in inoculated than control (not inoculated) ones. ash 90% logs. mineral elements Ca, Mn, Zn,...

Abstract The black timber bark beetle ( Xylosandrus germanus ) is a strongly invasive ambrosia and an important forest pest in Slovakia. This closely associated with symbiotic fungi used as its food source. We investigated the X. adults In this study, Beauveria bassiana , B. pseudobassiana Clonostachys rosea Fusarium oxysporum Ophiostoma quercus Phaeoacremonium scolyti Talaromyces amestolkiae were isolated identified by morphological molecular analyses. fungus was most frequently from living...

This article presents the ecological distribution of edible and medicinal mushroom Polyporus umbellatus in Central Europe. Our main motivation is to describe potential for commercial cultivation this species. All data considered study are based on records from 70 localities Slovakia. Fruiting bodies sclerotia have been recorded forests which beech, hornbeam, oak dominate, at altitudes ranging 150 935 m (mean altitude, 403 m). In Slovakia, these areas correspond warm, hilly, upland beech-oak...

This paper addresses the processes and investment evaluation of utilizing available dendromass in an easy close-to-nature way under Central European conditions Slovakia. Wood aspen (Populus tremula L.) that has generally been considered little economic value was efficiently used as a growth medium for oyster mushroom (Pleurotus ostreatus (Jacq.) P. Kumm.). The production fruiting bodies this were evaluated 5 years natural forest conditions. focused solely on wood, specifically, most valuable...

The mushroom today known as Ganoderma lingzhi has been used for centuries in the countries of Eastern Asia a very important medicinal mushroom. It prefers growing on rotten wood broadleaf trees and is mainly distributed tropics subtropics. Its relative G. lucidum occurs naturally almost all Earth, it colonizes mostly oak beech Central Europe. are similar species. To obtain qualitative parameters lucidum, several strains (five five ones) were chosen cultivated both Slovakia China, using chip...

Current research is focused on testing the cultivation of Paecilomyces hepiali mycelia various plant substrates and producing fungus or mycelial biomass with qualitatively interesting substances. P. was cultivated using solid-state fermentation different substrates. Mycelial then analyzed, antioxidant activity evaluated DPPH radical scavenging method for ethanolic extracts based a millet substrate (extract 1) chickpea 2). Extract 1 corresponds to half-maximal inhibitory concentration 1.73...

Abstract Two theories, explaining the time dependence of negative corona discharge current in air, are confronted with new experimental results. The influence ozone concentration on was experimentally confirmed dry air and mixtures nitrogen oxygen. Assuming that only dissociative electron attachment to molecule is a process being responsible for reduction component total mean current, value rate constant k = (3 ‐ 5.5) × 10 −9 cm −3 s −1 derived from measured concentration. calculated...

This research studies the influence of substrate on antioxidant activity alcohol extracts Paecilomyces hepiali. We used corn, rice, millet, and peas as substrates. Antioxidant was measured with DPPH radical scavenging method. Concentrations (6.25, 3.12, 1.56, 0.78, 0.39 mg/mL) were applied in all evaluations. Overall expressed concentration that decreased levels by 50% (IC50DPPH) for 7 methanol ethanol extracts. A comparison IC50DPPH allowed us to conclude are more active stable radicals...

Wood-inhabiting macromycete (WIM) communities in the ecosystem of uneven-aged spruce stands growing on former agricultural land were investigated relation to supply wood substrate, degree rot, and selected climatic ecological conditions. Altogether, 58 WIM species detected at research plots during 2016–2018. The abundance fruiting bodies richness increased from youngest oldest forest stands. highest numbers body recorded for Gymnopus perforans (11 756), Hypholoma fasciculare (2 971),...

Abstract The paper gives description of the growth conditions on output valuable components from fungus chaga. samples chaga represent two different regions Eurasia – Western Siberia and Czech Republic. results research proved that yield melanin in water extracts grown was 1.7% higher than analogue. Consequently, authors concluded harsher growth, which cause a slow fungus, lead to greater accumulation useful substances.

The Mushroom Training and Resource Centre (MTRC) is an organization aimed at helping to improve the standard of living for current future generations rural residents in Uganda through mushroom cultivation sales. This community was established 2007 with primary objective teaching people from marginalized areas how cultivate oyster a simple sustainable manner. fungi are grown on agricultural plant waste, which transformed into valuable food. production cycle, including formation fruiting...

Ambrosia beetles, particularly invasive species within the tribe Xyleborini, such as Xylosandrus germanus (Blandford, 1894), pose significant threats to various ecosystems and managed habitats worldwide. Monitoring these invaders is vital for effective pest management, typically accomplished through ethanol-baited traps. We compared trap efficacy using denatured ethanol versus absolute in orchards, tree nurseries, lumber yards northeastern Ohio, USA, finding that traps captured significantly...

There exist about 750 species of Cordyceps at present. A high price natural and its lack in nature caused that the attention has been focused to cultivation laboratory conditions. The demand for this “fungus-parasite” is still quite nowadays, as shown by amount commercial nutritional supplements. Phytochemical diversity ensured used an immunomodulatory antioxidant; it anti-cancer, anti-inflammatory, anti-diabetic, antibacterial, anti-HIV effects. In present study we on NMR IR...

Bareroot European beech (Fagus sylvatica L.) seedlings are frequently used in reforestation programs Central Europe. However, outplanting is often unsuccessful due to drought stress. In this study, the effects of a simulated water deficit and hydrogel ectomycorrhizal fungi (EMF) application were estimated on development 1 + seedlings. The roots 1-year-old bareroot treated with additives at time transplanting pots spring then exposed whole growing season under different watering regimes: (i)...

Various secondary metabolites isolated from Ophiocordyceps sinensis, the Chinese caterpillar fungus, have been reported to possess high therapeutic potential. Paecilomyces hepiali has even more biologically important chemical components with interesting pharmacological activity. Traditional medicine uses sinensis treat lung and respiratory system problems, hyposexuality, hypolipidemia kidney, or liver, heart, immune conditions. In addition, it used various forms of cancer, especially in...
