“…In our study, the decreased soil pH under inoculations of A. chlamydospora may be related to the enrichment of the acidophilic fungus Pluteaceae . The members of Pluteaceae have been reported to mainly adapted to grow in acidic soil with pH 4.5–4.99 with a strong ability to decompose organic matter, thus playing an important role in soil bioremediation (Mohammadi-Sichani et al, 2017 ; Kunca and Pavlik, 2019 ). However, the increase of soil organic carbon, especially under Monosporascus sp.…”

Although desert plants often establish multiple simultaneous symbiotic associations with various endophytic fungi in their roots, most studies focus on single fungus inoculation. Therefore, combined inoculation of multiple fungi should be applied to simulate natural habitats with the presence of a local microbiome. Here, a pot experiment was conducted to test the synergistic effects between three extremely arid habitat-adapted root endophytes (Alternaria chlamydospora, Sarocladium kiliense, and Monosporascus sp.). For that, we compared the effects of single fungus vs. combined fungi inoculation, on plant morphology and rhizospheric soil microhabitat of desert plant Astragalus adsurgens grown under drought and non-sterile soil conditions. The results indicated that fungal inoculation mainly influenced root biomass of A. adsurgens, but did not affect the shoot biomass. Both single fungus and combined inoculation decreased plant height (7–17%), but increased stem branching numbers (13–34%). However, fungal inoculation influenced the root length and surface area depending on their species and combinations, with the greatest benefits occurring on S. kiliense inoculation alone and its co-inoculation with Monosporascus sp. (109% and 61%; 54% and 42%). Although A. chlamydospora and co-inoculations with S. kiliense and Monosporascus sp. also appeared to promote root growth, these inoculations resulted in obvious soil acidification. Despite no observed root growth promotion, Monosporascus sp. associated with its combined inoculations maximally facilitated soil organic carbon accumulation. However, noticeably, combined inoculation of the three species had no significant effects on root length, surface area, and biomass, but promoted rhizospheric fungal diversity and abundance most, with Sordariomycetes being the dominant fungal group. This indicates the response of plant growth to fungal inoculation may be different from that of the rhizospheric fungal community. Structural equation modeling also demonstrated that fungal inoculation significantly influenced the interactions among the growth of A. adsurgens, soil factors, and rhizospheric fungal groups. Our findings suggest that, based on species-specific and combinatorial effects, endophytic fungi enhanced the plant root growth, altered soil nutrients, and facilitated rhizospheric fungal community, possibly contributing to desert plant performance and ecological adaptability. These results will provide the basis for evaluating the potential application of fungal inoculants for developing sustainable management for desert ecosystems.

“…P. umbellatus is rarely found in Asia, Europe, and North America. 21 The screening showed that by using only Allium species in water, a wide range of meaty and savory odor impressions were obtained in submerged basidiomycetes fermentations. This developed fermentation system can be used to generate meaty flavors that could be applied to various meat alternatives.…”

One of the main reasons for consumer rejection of plant-based meat alternatives is the lack of meaty flavor after cooking. In this study, a platform was developed to generate meaty flavors solely from Allium substrates (chives, leeks, ramsons, and onions) using basidiomycete-mediated submerged fermentations. Polyporus umbellatus-mediated fermentation of onions resulted in an intense meaty and liver sausage-like flavor under proper fermentation parameters. Using multisolvent and solvent-free aroma extractions coupled with gas chromatography−mass spectrometry−olfactometry, 5 odorants with high assigned flavor dilution (FD) factors (≥ 256) were identified in the fermented sample that have been reported in the literature as important aroma compounds of meat products: methyl palmitate, bis(2-methyl-furyl) disulfide, (E,E)-2,4-decadienal, γ-nonalactone, and eugenol. Using selected ion monitoring, the presence of bis(2-methyl-furyl) disulfide (meaty, savory, FD 256) after fermentation was confirmed. It was proposed that P. umbellatus enzymatically forms bis(2-methyl-furyl) disulfide from intermediates derived from the thermal degradation of thiamine.

“…The potential for collecting mushrooms in Slovakia may be even higher when not mycorrhizal species of fungi are also considered. Slovak mushroom pickers also often harvest other, not ectomycorrhizal, mushrooms as parasols (Macrolepiota procera and M. mastoidea), oyster mushroom (Pleurotus ostreatus), umbrella polypore (Polyporus umbellatus) or early false morel (Verpa bohemica) [56].…”

Mushrooming is a widespread leisure activity for a significant part of the Slovak population. From the point of view of the ecosystem services, it combines a provisioning service (mushrooms as food or delicacies) and a cultural service (mushroom picking as physical activity in nature). For urban residents, the forest is a refuge from the daily work routine, and mushrooming contributes significantly to improving their quality of life. For mushroom pickers living in rural areas, the occurrence and availability of mushroom harvesting sites are often even more important since it contributes to their diet or even provides an occasional income. We summarised the ecological preferences of selected ectomycorrhizal mushrooms and applied them as parameters for modelling the potential of forest stands for mushroom growing in central Slovakia. In the second step, we analysed the theoretical demand for wild mushrooms as a subsistence provisioning service for the local population with a special focus on socially disadvantaged inhabitants. The results showed that there is a spatial overlap of forest stands with a high potential for mushroom growing and the districts with the highest proportion of unemployment or of inhabitants receiving social benefits, and the best mushroom forest stands are situated within walking distance from the settlements. This supports the initial assumption that wild mushrooms may contribute to a better life for disadvantaged local communities.
