Construction of simplified microbial consortia to degrade recalcitrant materials based on enrichment and dilution-to-extinction cultures
2019
AbstractThe capacity of microbes degrading recalcitrant materials has been extensively explored from environmental remediation to industrial applications. Although significant achievements were obtained with single strains, focus is now going toward the use of microbial consortia because of advantages in terms of functional stability and efficiency. While consortia assembly attempts were made from several known single strains, another approach consists in obtaining consortia from complex environmental microbial communities in search for novel microbial species, genes and functions. However, assembling efficient microbial consortia from complex environmental communities is far from trivial d…
Comparison of Two Schizophyllum commune Strains in Production of Acetylcholinesterase Inhibitors and Antioxidants from Submerged Cultivation
2021
In recent years, fungi have been recognized as producers of acetylcholinesterase (AChE) inhibitors, agents important for the prevention of Alzheimer’s disease (AD). This study aimed to examine the AChE inhibitory, the antioxidative and antibacterial activity of two different Schizophyllum commune strains that originated from Serbia (SRB) and Italy (IT). Submerged cultivation of grown mycelia (M) and fermentation broth (F) of ethanol (EtOH) and polysaccharide (PSH) extracts lasted for 7, 14, 21 and 28 days. For AChE activity Ellman method was performed, while for antioxidative activity, sevendifferent assays were conducted: DPPH, ABTS, FRAP, SOA, OH, NO together with total phenolic content. …
Biology, cultivation, and medicinal functions of the mushroom Hericium erinaceum
2016
<em>Hericium erinaceum</em> (Bull.: Fr.) Pers. is an edible fungus of great significance in medicine. It is rarely found in Europe, in contrast, it is common in Japan and North America. Its fruitbodies have been well-known for hundreds of years in traditional Chinese medicine and cuisine. A cradle of <em>H. erinaceum</em> cultivation is Asia. In Eastern Europe is rare in natural habitats, but can be successfully cultivated. Both fruitbodies and mycelia are rich in active, health promoting substances. Tests of substances extracted from this mushroom carried out on animals and in vitro have given good results. They can be used in the treatment of cancer, hepatic disord…
Mycochemicals in wild and cultivated mushrooms: nutrition and health
2021
AbstractThe mushrooms have contributed to the development of active ingredients of fundamental importance in the field of pharmaceutical chemistry as well as of important tools in human and animal health, nutrition, and functional food. This review considers studies on the beneficial effects of medicinal mushrooms on the nutrition and health of humans and farm animals. An overview of the chemical structure and composition of mycochemicals is presented in this review with particular reference to phenolic compounds, triterpenoids and sterols, fatty acids and lipids, polysaccharides, proteins, peptides, and lectins. The nutritional value and chemical composition of wild and cultivated mushroom…
Human immunodeficiency virus infection in cells of myeloid-monocytic lineage.
1991
We established persistent infection with a strain of human immunodeficiency virus type 1, HTLV-IIIB, in a promyelomonocytic cell line, ML-1 (CD4 antigen nearly negative and CD4 mRNA negative), and a promonocytic cell line, THP-1 (CD4 antigen positive). Different reaction of giant cell formation was found after co-cultivation of infected and uninfected cells of ML-1, HL-60, THP-1 and U-937 cell lines with uninfected and infected MOLT4 (a T-lymphoma cell line).
Notes on a New Productive Strain of King Oyster Mushroom, Pleurotus eryngii (Higher Basidiomycetes), a Prized Italian Culinary-Medicinal Mushroom
2015
In this paper, the authors provide data on a culinary-medicinal, host-specific variety of P. eryngii species-complex that is known in Italy as "cardoncello". A species description, the techniques of isolation of a new strain (C-142-c), and the preparation of the substratum are illustrated. Data on the productivity of substratum inoculated with C-142-c strain and the nutritional value of cultivated "cardoncello" mushrooms are also provided.
Cryptic Secondary Metabolites from the Sponge-Associated Fungus Aspergillus ochraceus
2019
The fungus Aspergillus ochraceus was isolated from the Mediterranean sponge Agelas oroides. The initial fermentation of the fungus on solid rice medium yielded 16 known compounds (4&ndash
Up-to-date distribution, ecology and cultivation of Pleurotus eryngii (DC.) Quél. var. thapsiae Venturella, Zervakis & Saitta in Sicily
2012
Venturella et al. [1] described a new taxon named Pleurotus eryngii (DC.) Quél. var. thapsiae Venturella, Zervakis & Saitta (Madonie Mts) on Thapsia garganica L. and provided ecological data on the locus classicus. P. eryngii var. thapsiae was reported on pastures evolved, from 1000 to 1500 m a.s.l., on limestone and is characterized by a double period of fructification (autumn and spring). P. eryngii var. thapsiae is a choice wild edible mushroom belonging to a special group of Pleurotus species which appear in nature in close association with Apiaceae plants. As part of the project's census of fungi in Sicily two new localities of growth were localized in the Natural Reserves of Capo Gall…
Insights in ChAdOx1 nCoV-19 vaccine-induced immune thrombotic thrombocytopenia
2021
Abstract SARS-CoV-2 vaccine ChAdOx1 nCoV-19 (AstraZeneca) causes a thromboembolic complication termed vaccine-induced immune thrombotic thrombocytopenia (VITT). Using biophysical techniques, mouse models, and analysis of VITT patient samples, we identified determinants of this vaccine-induced adverse reaction. Super-resolution microscopy visualized vaccine components forming antigenic complexes with platelet factor 4 (PF4) on platelet surfaces to which anti-PF4 antibodies obtained from VITT patients bound. PF4/vaccine complex formation was charge-driven and increased by addition of DNA. Proteomics identified substantial amounts of virus production-derived T-REx HEK293 proteins in the ethyle…
Medicinal Mushrooms as Part of the "Third Mission" Activities of Univesities - A Science to Business Initiative Related to Mycotherapy
2021
In Italy, the National Agency for the Evaluation of the University System and Research (ANVUR) carries out a systematic evaluation of the "Third Mission" activities of universities and research bodies. In this perspective, universities already engaged in research on medicinal mushrooms and on their potential applications in the industrial sector set the frame for collaboration with large, well-reputed private companies. In Italy, one of the major problems of mycotherapy is related to lack of certification and the dubious origin/identity of mushroom extracts used by the industry. Hence, products deriving from medicinal mushrooms that are in trade do not often meet the required quality criter…
