Opis:
Effects of ultrasound, high pressure argon, and treatments comprising their combinations on physicochemical and microbiological characteristics of white mushrooms were studied during 9 days of storage at 4°C. High pressure argon treatments were relatively effective in retaining firmness and were found to maintain the cell integrity. White mushrooms firmness after 9 days of storage was increased from 2.79 N for untreated mushrooms up to 3.01, 3.24, 3.58 N for ultrasound, treatments comprising ultrasound and high pressure argon, high pressure argon, respectively. Similarly, the loss of water, ascorbic acid and total soluble solid in fresh mushroom was also greatly reduced by the high pressure argon treatment. The ultrasound treatment followed by treatments comprising ultrasound and high pressure argon and high pressure argon, respectively exhibited a pronounced effect on retarding browning and in delaying mesophilic and psychrotrophic bacteria, yeasts and moulds growth in white mushroom, compared to the control during 9 days of cold storage. Treatments comprising ultrasound and high pressure argon treatment delayed pseudomonas growth, implying that it could extend shelf life of white mushrooms to 9 days at 4°C.

Opis:
Powszechnie spożywane gatunki grzybów pod wpływem działania promieni UV (światło słoneczne lub lampa UV) mogą generować istotne z punktu widzenia żywieniowego zawartości witaminy D. Główną formą witaminy D, która występuje w grzybach jest D2 (ergokalcyferol C28H44O) oraz mniejsze ilości D3 (cholekalcyferolC27H44O) i D4 (22-dihydroergokacyferol C28H46O). Witamina D3 w największych ilościach znajduje się w produktach pochodzenia zwierzęcego. Źródłem witaminy D2 są grzyby. Pomimo tego, że procesy technologiczne lub przechowywanie powodują spadek jej zawartości, zawartość D2 w grzybach może stanowić dobre jej źródło w diecie. Celem pracy była analiza aktualnych danych literaturowych w zakresie wpływu promieniowania UV na syntezę witaminy D2 w grzybach, a także wpływu ich przechowywania i obróbki termicznej na jej zawartość i biodostępność.
Commonly consumed mushroom species exposed to UV radiation (sunlight or UV lamp) can generate nutritionally important amounts of vitamin D. The most common form of vitamin D in mushrooms is D2, with lesser amounts of vitamin D3 and D4, while vitamin D3 is the most common form of vitamin in animal products. Although the level of vitamin D2 in mushrooms exposed to UV radiation may decrease with storage and cooking, if they are consumed before the expiry date, the level of vitamin D2 is likely to remain above 10 μg / 100 fresh masstherefor mushrooms have the potential to be the only non-animal and unenriched food source that can provide a significant amount of vitamin D2. This review analyses current information on the role of UV radiation in enhancing concentration of vitamin D2 in mushromms, the effects of storage and cooking on D2 content, and bioavailability of vitamin D2 from mushrooms.

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:
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:
Demand for Ganoderma lucidum basidiocarps on the global market is increased due to its numerous health benefits. As they are rare in nature and traditional cultivation on logs is not ecologically and economically justified method, current trend is finding of good alternative substrate for production. Whether wheat straw, the most abundant crop residue in Europe, could be a novel substrate for G. lucidum cultivation was the question which led to the definition of the goals. Two wild and one commercial strains were objects of the study. Despite some morphological differences among basidiocarps, all strains belong to G. lucidum sensu stricto, which was confirmed by analyses of ITS, tef1-a and rpb2 gene sequences. Wheat straw showed as a good substrate, namely the periods required for the complete colonisation of wheat straw by mycelium as well as the formation of primordia and basidiocarps were relatively short. The totally fresh and dry yield and biological efficiency were also significant. If it is taken into consideration that untreated wheat straw was used, validities of its introduction in industrial-scale G. lucidum cultivation can be demonstrated.

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.

This study aimed to assess the element content of Porcini mushrooms collected from broadleaf Mediterranean forests (NW Italy) and underlying soil layers, and to elucidate the chemical connection between the mushrooms and their geographic site of origin. Comparing the elements in mushrooms with those in soil samples, we observed that the concentration of some microelements detected in mushrooms had similar distribution as that measured in both the soil layers assessed, especially with surface soil. Statistical analyses showed that the microelement pattern in mushrooms reflects the soil site of origin. Moreover, by comparing our results with other studies, we observed that the soil where Porcini grow is characterized by a high concentration of zinc. Some toxic elements were also detected in mushroom samples. Analysis of elements in mushrooms and soil layers can be used for quality assurance of natural products and help distinguish them from uncertified and unknown-origin products.

This study aimed determining the contents of soluble protein, free amino acid, phenolic, flavonoid, soluble carbohydrate, sugars (glucose, fructose and sucrose) and elements in selected wild growing and cultivated mushroom species collected from various locations of Turkey. Significant differences (P < 0.05) were found for the contents of total free amino acid, soluble protein, phenolic, flavonoid, soluble carbohydrate and sugars. The total free amino acid, soluble protein, phenolic, flavonoid and soluble carbohydrate contents of mushrooms ranged from 33.57–126.57 mg g–1, 2.77–7.55 mg g–1, 28.68–157.39 mg g–1, 8.55– 30.66 mg g–1 and 59.89–343.55 mg g–1, respectively. Elemental analysis showed that mushrooms contained significant amounts of potassium (1345.07–9310.17 mg kg–1), phosphorus (1462.44–6159.45 mg kg–1), calcium (18.78–349.15 mg kg–1), sulphur (952.41–12486.63 mg kg–1), iron (80.62–606.26 mg kg–1), manganese (22.65–147.57 mg kg–1), zinc (103.26–522.81 mg kg–1) and selenium (0–115.40 mg kg–1). Nutritient composition varied with mushroom species. The means of total soluble protein, total phenolic, total flavonoid, potassium, phosphorus, sulphur, chlorine, sodium, iron, calcium, manganese, selenium, zinc and copper contents in wild growing mushrooms were found higher than cultivated mushrooms.

Opis:
Sulfonamides are one of the oldest antibacterial drugs that remain still in use in humans and animals treatment. These compounds block the biosynthesis of folate in bacterial cells, thus inhibiting growth of bacteria. In order to potentiate the pharmacological activity, sulfonamides are often combined with trimethoprim. The role of those bacteriostatic agents has decreased over the years, mainly due to increasing bacterial resistance which is an effect of the inappropriate use of sulfonamides. There are still several compounds which are administered in humans to treat not only bacterial infections, but also protozoan ones (e.g. toxoplasmosis), for instance sulfamethoxazole, sulfacetamide, sulfathiazole. More number of sulfonamides is used in veterinary. According to this fact, there is a considerable adverse effect of those compounds on the environment: sulfonamides, after having been excreted from animal organisms, are present in soil and water, including groundwater. Hence there is a strong need to find effective methods of sulfonamides degradation in order to protect the environment.

Opis:
An oyster mushroom (Pleurotus ostreatus (Jacq.) P. Kumm) is a cultivated species of mushrooms characterizing with unique culinary and medicinal properties. Its’ nutritional value comes from proteins, carbohydrates, fatty acids, vitamins and mineral nutrients present in their fruitbodies. Because of a high content of fiber (mainly chitin) and low content of fat, they are a valuable element of an atherosclerosis diet. The fruitbodies of oyster mushrooms are an important source of biologically active substances, specific polysaccharides and polyphenols, which influence a human immune system, so that it fights against cancer cells. ß-D-glucans have an advantageous effect on digestive system, lower blood cholesterol and triglycerides level, decrease the risk of ischaemic heart disease. Active substances present in the mushrooms have antioxidant, antibacterial, antiviral, antidiabetic and anti-inflammatory properties. Numerous scientific studies prove high efficiency of the therapy with the use of preparations and extracts from Pleurotus ostreatus mycelia, both in prophylaxis and cure of civilization diseases, atherosclerosis and cancer.

Mushrooms can be used in diet as nutraceutical or functional foods for promoting and maintaining health quality and health longevity. Mushrooms just like medicinal plants can be utilized in the form of powder or extract as curative agents of several diseases and in providing a healthy diet. In current study, ten different mushroom species were collected from Azad Jammu and Kashmir. The selected mushrooms were assessed for their nutritional value, biological activities and fatty acid profiling. Before extraction, proximate analysis of all selected mushrooms was performed. Protein, fat, ash and total carbohydrate contents ranged from 10-30%, 0.43-8.08%, 1.1-9.14%, 12.47-92.52%, respectively. Then mushrooms were extracted with three different solvents n-hexane, ethyl acetate and methanol for the assessment of their antioxidant potentials through different antioxidant assays like total phenolics, total flavonoid contents and DPPH inhibition assay. The order of antioxidant potential in different solvent is methanol>Ethyl acetate>n-hexane. Quantification of fatty acids by GC/MS analysis revealed that stearic acid, palmitic acid, oleic acid, linolenic acid were present in significant quantity in different mushrooms and unsaturated fatty acids were found abundant over saturated fatty acids in all the selected mushrooms. So presence of fatty acids in studied samples is one of the main biologically active ingredients from mushrooms. The study concluded that the selected mushrooms from different regions of Azad Jammu and Kashmir are of nutritional importance having significant antioxidant potential and contains several unsaturated fatty acids which contribute to the nutritional value of mushrooms.

Chemical elements in the samples of wild edible mushrooms of the Morchella group collected from different unpolluted Sicilian sites was analyzed by the ICP-MS (method) to detect the content of their minerals and determine whether soil geology and geochemistry can influence the chemical composition in fungi. Results showed that the mushroom samples mainly contained a high concentration of K and P and a wide variety of minor and trace elements (V, Mo, Pb, Ce, Cs, Zr), including heavy metals. Statistical analysis showed that the mushrooms differed in their content of minor and trace elements based on the geological/geographic site of origin. Comparison with other studies showed differences in the content detected in the Sicilian morels with those collected from other geographical sites. Conversely, different fungal species collected from similar geological sites in Sicily showed different patterns of accumulation of the elements confirming that bioconcentration in fungi is species- and site-dependent.

Opis:
Mushroom foraging is very popular in some regions of the world. Sometimes toxic and edible mushrooms are mistaken by mushroom collectors, leading to serious human poisoning. The group of mushrooms highly dangerous for human health includes Amanita phalloides. This mushroom produces a toxic octapeptide called α-amanitin which is an inhibitor of nuclear RNA polymerase II. The inhibition of this polymerase results in the abortion of mRNA synthesis. The ingestion of A. phalloides causes liver failure due to the fact that most of the toxin is uptaken by hepatocytes. The hospitalization of poisoned patients involves the removal of the toxin from the digestive tract, its dilution in the circulatory system and the administration of therapeutic adjuvants. Since there is no effective antidote against amanitin poisoning, in this study we developed a DNA aptamer exhibiting specific binding to α-amanitin. This aptamer was selected using the SELEX (Systematic Evolution of Ligands by Exponential Enrichment) method. Next, its ability of toxin removal from aqueous solution was confirmed by pull-down assay. The aptamer region sufficient for α-amanitin binding was determined. Finally, the dissociation constant of the α-amanitin/DNA aptamer complex was calculated.
