Opis:
The structure-bioactivity relationship of Tremella fuciformis polysaccharides (TFPs) in anti-aging in vivo is rarely reported. In the present study, a purified TFP, named HM, mainly composed of mannose, fucose, xylose, and glucose in a molar ratio of 4.14:0.98:0.81:0.62, was obtained from the fruiting body of T. fuciformis. Subsequently, two differentially degraded TFPs, named MM and LM, respectively, were prepared by a combined method of ultrasonic irradiation (US) and H2O2 treatment. Their structural properties, scavenging activities against free radicals in vitro, and anti-aging effects on D-galactose-induced aging of mice were determined. The average molecular weight of HM, MM, and LM was 58.3×106, 4.68×106, and 3.14×105 Da, respectively. All three TFPs were devoid of triple helix conformation and exhibited concentration- and molecular weight-dependent scavenging activity against radicals. The TFPs markedly relieved skin aging, effectively attenuated oxidative stress, and significantly decreased inflammation in D-galactose-induced aging mice. MM exhibited the best anti-aging effect among the TFPs. Additionally, TFPs partially restored the alterations in pH and the total content of short-chain fatty acids (SCFAs) in the colon but exhibited various impacts on the content of the individual SCFAs. These findings would provide rational guidance for a better application of TFPs in anti-aging foods and expand our understanding of the structure-function relationship of mushroom polysaccharides.

Opis:
Ganoderma sinense, a well-known medicinal macrofungus of Basidiomycetes, is widely used in traditional medicine for promoting health and longevity in East Asia. The fruiting bodies of G. sinense contain polysaccharides, ergosterol, and coumarin, which have antitumor, antioxidant, and anticytopenia activities. Mushroom cultivation requires suitable conditions for the formation of fruiting bodies and yield. However, little is known about the optimal culture conditions for mycelial growth and cultivation of G. sinense. In this study, the successful cultivation of a G. sinense strain collected from the wild was reported. The optimal culture conditions were identified by examining one factor at a time. The results of this study revealed that the nutritional requirements for the optimal mycelial growth of G. sinense were fructose (15 g/l) as the carbon source and yeast extract (1 g/l) as the nitrogen source. The optimal pH and temperature for G. sinense were 7 and 25–30EC, respectively. The mycelia grew fastest in treatment II (69% rice grains + 30% sawdust + 1% calcium carbonate). G. sinense produced fruiting bodies under all tested conditions and showed the highest biological efficiency (2.95%) in treatment B (96% sawdust, 1% wheat bran, 1% lime). In summary, under optimal culture conditions, G. sinense strain GA21 showed satisfactory yield and a high potential for commercial cultivation.

Opis:
Mushrooms are a rich source of antioxidants and nutritional values. Edible mushrooms, however, are susceptible to various diseases such as dry bubble, wet bubble, cobweb, bacterial blotches, and mites. Farmers face significant production losses due to these diseases affecting mushrooms. The manual detection of these diseases relies on expertise, knowledge of diseases, and human effort. Therefore, there is a need for computer-aided methods, which serve as optimal substitutes for detecting and segmenting diseases. In this paper, we propose a semantic segmentation approach based on the Random Forest machine learning technique for the detection and segmentation of mushroom diseases. Our focus lies in extracting a combination of different features, including Gabor, Bouda, Kayyali, Gaussian, Canny edge, Roberts, Sobel, Scharr, Prewitt, Median, and Variance. We employ constant mean-variance thresholding and the Pearson correlation coefficient to extract significant features, aiming to enhance computational speed and reduce complexity in training the Random Forest classifier. Our results indicate that semantic segmentation based on Random Forest outperforms other methods such as Support Vector Machine (SVM), Naïve Bayes, K-means, and Region of Interest in terms of accuracy. Additionally, it exhibits superior precision, recall, and F1 score compared to SVM. It is worth noting that deep learning-based semantic segmentation methods were not considered due to the limited availability of diseased mushroom images.

Opis:
Three forests, Beliatore, Gangajal-ghati (G-ghati), and Joyur, were surveyed for mushroom collection and biodiversity. Mushrooms in the rhizospheric zone of some trees, such as Shorea robusta, Petrocarpus marsupium, Terminalia bellrica, and Madhuca indica, were identified at the molecular level as Asterius asiaticus. Thereafter, the ecological diversity of this mushroom was determined in the forests. The diversity indices of Shorea robusta in the Beliatore, Joypur, and Gangajal-ghati forests were 2.303, 2.178, and 2.36, respectively. Notably, the diversity index of Madhuca indica in the Beliatore and Joypur forests was nearly the same as that in the Gangajal-ghati forest, with a value of 2.29. The total phenolics contents of the hot water, acetone, and hexane extracts of this mushroom were 6.8 ± 0.15, 3.95 ± 0.15, and 2.16 ± 0.26 mg GAE/g, respectively, and the total flavonoid contents were 2.03 ± 0.12, 1.65 ± 0.2, and 1.01 ± 0.08 mg QE/g, respectively. The ascorbic acid contents in the hot water, acetone, and hexane extracts were low. The antioxidant activity of the extracts was determined using the DPPH (1,1-Diphenyl-2-picrylhydrazyl) assay. The IC50 values of the hot water, acetone, and hexane extracts were 42.54 ± 1.25c µg/ml, 54.06 ± 1.50b µg/mL, and 82.97 ± 1.58a µg/ml respectively while that of the synthetic antioxidant, BHA (butylated hydroxyanisole), was 32.41 ± 1.26d µg/mL. Overall, the hot water extract of this mushroom had the highest antioxidant content and displayed the best radical scavenging power.

Opis:
Through this paper, the author tries to explore a simple yet complex question: how do we decentralize the human presence in conversations about climate-change? To do so, this speculative climate 2ction is presented through the non-human narrative perspective of mycelium (fungi). The speculative fiction provides a space for re-thinking our ontological and epistemological strategies and categorizations of nature/culture division, as well as how we understand nature in relation to human.The speculative climate-fiction proposes a reconsideration of human in relation to nature/climate, through fungi. It further explores how sensory, bodily, and multimodal methodologies may work in interaction to produce new possibilities to explore the corporealities of human-nature relationships and how a non-anthropocentric understanding of climate-change can allow for an emerging engagement with a vast mesh of human and beyond-human agencies. Drawing inspiration from Sylvia Plath, Ursula K. Le Guin, Margaret Atwood, and using Erin Manning’s understanding of a5ect as having a feltness that we often experience as a becoming-with, in this case, a becoming-with nature, the speculative-fiction (SF) is written as a dialogue between fungi and human. The SF also uses artwork created with mushrooms, fungal roots, as well as mushroom extracts, to exaggerate the presence of beyond-human beings in a new onto-epistemic strategy that reconsiders climate change and human–nature relationships.

Opis:
Oyster mushroom (Pleurotus ostreatus) is one of the most widely consumed mushrooms in the world. Its spores are highly potent allergens, but their main allergen, Pleo, has so far been very rarely reported. In indoor farms, fungal spores are often found to be floating in the air. This study presents a case of a non-atopic, healthy 32-year-old woman who opened an oyster mushroom farm with her husband. During the first harvest, after 30-minute exposure, she experienced dyspnoea. Similar symptoms occurred several more times while on the farm. A month later, during packing and sorting mushrooms, after 10 min, she again felt dyspnea, accompanied by weakness, rapid pulse, and skin itching with urticaria which occurred on her forearms. Immediately after one of the exposures to oyster mushrooms, spirometry was performed. The results showed a reduced airflow obstruction. Standard skin prick tests with an inhalant and food allergens were also performed – all rendering negative results. The diagnosis also included a prick-to-prick test with oyster mushrooms (a wheal size of 12 mm), this time with a positive result. Increased total IgE (78 iu/ml) in the serum was recorded. On the basis of her medical history, reported symptoms and diagnostic tests, the patient could be diagnosed with occupational anaphylaxis and work-related asthma. A constant exposure of indoor mushroom cultivators to Pleurotus ostreatus spores increases the risk of respiratory allergy development. An environmental monitoring of oyster mushroom spores is reasonable in the industry, as it may prove useful in the prevention of the disease.

Opis:
In this study, wild edible mushroom collected from Rivers and Imo state Nigeria were evaluated for heavy metals and dietary intake risks assessment. Four species of edible mushrooms were collected each in Imo (Lentinus squarrosulus, Pleurotus ostreatus, Lenziles betulina and Grifola polypilus frondosa) and River state (Lentinus squarrosulus, Pleurotus tuber-regium, Lenziles betulina, Auricularia aurucula) and metals extracted using HNO3 before analysis using flame atomic absorption spectrometry (F-AAS) in Varian AA 240 FS apparatus. Results showed that all metals showed concentrations lower than the permissible limits of World Health Organization (WHO) and Food and Agricultural Organization (FAO) while Pb was not detected in all samples analyzed and Cd in samples collected from Rivers state. However, Cd was only detected (0.003 mg/kg) in one sample (Lenziles betulina) collected from Imo state. Fe exceeded recommended values in Lentinus squarrosulus, Pleurotus ostreatus and Lenziles betulina in Imo State. Bioaccumulation factors for all mushrooms were generally low (< 3). However, the potential tolerable weekly intake and target hazard quotient values for the four mushroom species were usually extremely low except for Fe (2.24) in Lenziles betulina. Consumption of mushrooms from these areas might pose no potential risk in terms of heavy metals except for Fe content in Lenziles betulina from Rivers state. However, in general, it can be concluded that the consumption of the studied mushroom species from all sites does not present any health risk arising from their regular consumption.

Opis:
Pleurotus pulmonarius (Fr.) Quel. is a mushroom species that occurs widely in nature on all continents except Antarctica. It is most common in North America. Its fruiting bodies are characterised by a mild taste and a slight anise aroma. These mushrooms are valued as a source of nutrients and substances with a healing effect. The anticancer, anti-inflammatory and antioxidant properties of P. pulmonarius have been scientifically proven, as well as its strong antihyperglycemic activity. P. pulmonarius is easy to grow because it has a very aggressive mycelium towards cellulosecontaining materials. In Poland, it can be grown on substrates based on cereal straw and various types of organic waste, including agricultural, horticultural, textile and forestry. In intensive crops, the substrates are also enriched with protein and carbohydrates. On an industrial scale, P. pulmonarius is grown primarily in Asia and North America on locally available organic materials.

Opis:
Background. The dry bubble disease, caused by Lecanicillium fungicola, is the most common fungal disease of white button mushroom (Agaricus bisporus). The aim of this study was to estimate the effectiveness of two chemical agents based on periacetic acid and biopreparations Effective Microorganisms (EM) in inhibiting the growth of L. fungicola isolated from infected fruiting bodies of button mushrooms. Material and methods. The material was the pathogen L. fungicola isolated from bottom mushrooms, treated with disinfectants: Agrosteril (in concentration 1, 1.5, 2, 2.5, 3, 3.5%), Larasept (in concentration 0.2%, 0.5%, 1%) and various configurations with biopreparations based on effective microorganisms (EM). The activity of the chemical preparations was assessed in a plate (on PDA medium) and pot experiment (in infected casing soil). The fungicidal efficacy of EM preparations was performed only in vitro. Results. In a plate experiment Agrosteril disinfectant caused the complete inhibition of pathogen development at each tested concentration. In the case Lerasept the lack of mycelium growth was obtained only after the application of the highest dose of 1%. Biopreparation EM-5 and its combination with EM-NA in a dose of $100 mg·cm^(-3)$ of the medium turned out to be the most effective of EM preparations in inhibiting the development of L. fungicola. Those preparations also caused a significant decrease in sporulation of the pathogen. Chemical preparations applied in the form of sprinkling to the casing infected with the fungi turned out to be less effective. The highest decrease in the pathogen number was obtained on 7th day from inoculation of the casing. Conclusion. Tested disinfecting preparations were characterized by strong fungicidal properties in vitro. Based on the pot experiment it was found that chemical preparations used for disinfecting the casing, applied in doses recommended by the producer, caused only a partial inactivation of L. fungicola.
Celem badań było określenie skuteczności środków chemicznych Agrosteril i Lerasept oraz preparatów na bazie efektywnych mikroorganizmów EM w hamowaniu rozwoju patogenicznego grzyba Lecanicillium fungicola wyizolowanego z uprawy pieczarek. W doświadczeniu płytkowym preparat Agrosteril w każdym testowanym stężeniu (1%, 1,5%, 2%, 2,5% 3%, 3,5%) powodował całkowite zahamowanie rozwoju patogena. Natomiast pod wpływem Leraseptu brak wzrostu grzybni stwierdzono tylko po zastosowaniu najwyższej dawki 1%, zaś w niższych koncentracjach 0,2% i 0,5% jego działanie było słabsze. Spośród preparatów EM najbardziej skutecznym okazał się EM-5 i jego kombinacja z EM-NA w dawce $100 mg·cm^(-3)$ pożywki. Preparaty te również powodowały istotny spadek zarodnikowania. Na podstawie doświadczenia wazonowego stwierdzono, że użyte do odkażania okrywy preparaty chemiczne powodowały tylko częściową inaktywację L. fungicola.

Using titanium driven blind bolts with pin instead of ordinary hammer-bucked rivets, can improve the fatigue life of element made of aluminum alloy AW 2024T3. There are advantages of replacing riveted joints with modified hybrid (rivet & adhesive) joints in threefold increase in fatigue life of repaired airframe structures.

Opis:
The fruiting bodies of Hericium erinaceus have been widely used for the treatment of dyspepsia, chronic gastric ulcers, and enervation. There remains a lack of data on the role of an ethanol extract from H. erinaceus (EEH) on ethanol-induced gastric ulcers. The ethanol-induced experimental gastric injury model was used to evaluate the gastroprotective activity of extracts. Ultra-high performance liquid chromatography-triple quadrupole-time of flight tandem mass spectrometry (UPLC-Triple-TOF-MS) analysis was used to identify the possible compounds present in EEH. Transcriptome sequencing(RNA-seq) and bioinformatics analyses were conducted to reveal the characteristics and molecular mechanism underlying EEH’s protective effect of on gastric tissue injury. Administration of EEH at doses of 0.625, 1.25, and 2.5 g/kg body weight prior to ethanol ingestion dose-dependently inhibited gastric ulcers. EEH also significantly increased superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) content in the gastric tissue. Twelve compounds from EEH were identified including three diterpene compounds, two heteroterpene compounds, three isoindolinone compounds, one aromatic compound, N-(1-deoxy-D-fructos-1-yl)-L-valine, adenosine, and lumichrome. These compounds promote the inhibition of pathways involved in gastric ulcer formation. The RNA-seq results suggest that EEH indirectly protects the gastric tissue from injury by regulating the cell cycle and biological functions, up-regulating several signal molecules, or activating several proteasome functions. It was concluded that EEH represents a potential therapeutic option to reduce the risk of gastric ulceration.

Opis:
Plant material obtained by pruning and production of deciduous fruit trees was evaluated as substrates for the production of the oyster mushroom, Pleurotus ostreatus. Lignified branches and stems from peach, apple, and pear trees were processed using a ripping machine to reduce the size of chips and to optimize disinfection. A completely randomized experimental design was proposed with six treatments (novel substrates) and one absolute control (100% hay substrate). Morphological variables such as thickness and diameter of the pileus, stipe length were assessed, as well as production variables (sprouting, fresh weight, and biological efficiency) and bromatological analysis (ash, ethereal extract, crude fiber, and crude protein). Apart from the 100%-hay substrate, biological efficiency ranged between 27% (100% apple tree as the substrate) and 140% (50% hay + 50% peach tree as the substrate). According to morphological analysis, the highest diameters were recorded from mixed substrates (50% hay + 50% wood), and a highly significant positive correlation was found between diameter and stipe length. Morphological parameters were not significantly correlated with biological efficiency. Analysis of biological efficiency confirmed that mixed substrates clustered together with 100%-wood substrates. Bromatological analysis showed that the mixed substrate (50% hay + 50% pear tree) had the highest protein content among the novel tested substrates. Bromatological parameters were not significantly correlated with biological efficiency. In conclusion, pruning residues from fruit trees can be valuable by using them as substrates for the cultivation of P. ostreatus. Production is quantitatively competitive with that using hay, on the condition that wood is mixed with hay.

Opis:
Humans have used mushrooms from the beginning of their history. However, during the last few decades, the market demand for these fruiting bodies has increased significantly owing to the spread in the capabilities of culinary and pharmacological exploitation. Natural mushroom resources have become insufficient to meet the support needs. Therefore, traditional methods of extensive cultivation as well as modern technologies have been exploited to develop effective growing recommendations for dozens of economically important mushroom species. Mushrooms can decompose a wide range of organic materials, including organic waste. They play a fundamental role in nutrient cycling and exchange in the environment. The challenge is a proper substrate composition, including bio-fortified essential elements, and the application of growing conditions to enable a continuous supply of fruiting bodies of market quality and stabilized chemical composition. Many mushroom species are used for food preparation. Moreover, they are treated as functional foods, because they have health benefits beyond their nutritional value, and are used as natural medicines in many countries. Owing to the rapid development of mushroom farming, we reviewed the growing technologies used worldwide for mushroom species developed for food, processing, and pharmacological industries.

Opis:
Fungal diseases are a persistent problem in the cultivation of white button mushrooms (Agaricus bisporus). The chemical control of pathogens is becoming less effective and less desirable, so new ways to limit these infections are urgently required. What is more, the disease is mostly controlled through cultural practices and good hygiene on mushroom farms. The aim of this study was to evaluate the fungicidal effects of ozone on fungal pathogens of common mushrooms. Experiments with the use of ozone gas for disinfection of growing rooms after the completion of the mushroom growing cycle were carried out. The fungicidal effectiveness of ozone fumigation was evaluated on the basis of the survival rate of the spores of the pathogens tested (Lecanicillium fungicola, Cladobotryum dendroides, Mycogone perniciosa, and Trichoderma aggressivum). Spore suspension was applied to aluminum plates and then was exposed to gaseous ozone. The assessment of the growth of colonies of fungal isolates obtained from infected surfaces was carried out using Rodac contact test plates. The results showed that L. fungicola, M. perniciosa, and C. dendroides isolates were sensitive to the gas ozone. In order to achieve 100% efficacy against Mycogone strains, a minimum of 6 hours of ozonation had to be applied, whereas for Cladobotryum strains, a minimum of 8 hours had to be applied. The Lecanicillium species was the most sensitive to ozonation because 30 minutes of ozonation was enough to gain 100% inhibition of its growth. No satisfactory results were obtained in the case of the pathogenic species of Trichoderma, regardless of the experimental conditions. Nevertheless, this study has demonstrated the usefulness of ozone as a disinfectant for empty growing rooms after the completion of the mushrooms’ cultivation cycle.
