Abstract (sommario):
Epichloë endophytes, fungal endosymbionts of Pooidae grasses, are commonly utilized in forage and turf industries because they produce beneficial metabolites that enhance resistance against environmental stressors such as insect feeding and disease caused by phytopathogen infection. In pastoral agriculture, phytopathogenic diseases impact both pasture quality and animal production. Recently, bioactive endophyte strains have been reported to secrete compounds that significantly inhibit the growth of phytopathogenic fungi in vitro.

Abstract (sommario):
The purpose of this work was to screen clinical isolates of actinomycetes producing nonpolyenic antifungals. This choice was made to limit the problem of rediscovery of well-known antifungal families, especially polyenic antifungals. One hundred and ten strains were tested, using two diffusion methods and two test media, against three yeast species and three filamentous fungi. Among 54 strains (49%) showing antifungal activity, five strains belonging to the genus Streptomyces were active against all test organisms and appeared promising. These results indicate that clinical and environmental i

Abstract (sommario):
Emerging and reemerging fungal infections are very common in nosocomial and non-nosocomial settings in people having poor immunogenic profiles either due to hematopoietic stem cell transplants or are using immunomodulators to treat chronic inflammatory disease or autoimmune disorders, undergoing cancer therapy or suffering from an immune weakening disease like HIV. The refractory behavior of opportunistic fungi has necessitated the discovery of unconventional antifungals. The emergence of black fungus infection during COVID-19 also triggered the antifungal discovery program. Natural products a

Background/Objectives: Endophytic fungi are valuable sources of bioactive compounds with potential therapeutic applications. This study aimed to evaluate the antifungal activity of secondary metabolites produced by Fusarium sp. isolated from Dizygostemon riparius, with particular focus on the impact of culture medium supplementation with halogenated and metallic additives on metabolite production. Methods: The fungus was cultivated in standard Czapek medium and media supplemented with NH4Br or MnCl2. Methanolic extracts were obtained, fractionated, and chemically characterised via LC-ESI-HRMS.

Abstract (sommario):
There is a need for new alternative sources of exogenous antifungals to replace those currently used in agriculture. Actinobacteria are gram-positive bacteria with a wide variety of secondary metabolites, which produce around two-thirds of all naturally occurring antibiotics in current clinical use, as well as many anticancer, anthelmintic and antifungal compounds. Consequently, these bacteria are of great importance for agricultural biotechnology, since they can be produced and applied in fields that do not promote resistance among fungi that attack plants.

Abstract (sommario):
Usnea barbata (L.)F.H.Wigg. - known as “old man’s beard”, “tree moss”, “songluo” is a lichen in the family Parmeliaceae, genus Usnea. Usnea species have recorded history of therapeutic use dating back over three thousand years in Chinese medicine. The lichen secondary metabolites have shown an impressive range of biological proprieties, including antibiotic, antifungal, antiviral, anti-inflammatory, or anticancer activities. In this study, the antitumor activity of Usnea barbata extract was evaluated by observing the morphological changes on squamous cells carcinoma cell-line CAL 27 (ATCC® CRL

Abstract (sommario):
Fusarium oxysporum spp. causes Panama disease in bananas and crown and root rot in an array of vegetables and field crops, but increased regulations have restricted the use of many conventional chemical pesticides, and there are a limited number of commercially available products effective against them. The soil microbiome represents a largely untapped reservoir of secondary metabolites that can potentially antagonize fungal pathogens. However, most soil bacteria cannot be cultivated using conventional techniques and therefore most of these compounds remain unexplored. The overall goal of this

Abstract (sommario):
The involvement of glycans in microbial adherence, recognition and signaling is often a critical determinant of pathogenesis. Although the major glycan components of fungal cell walls have been identified there is limited information available on its ‘minor sugar components’ and how these change during different stages of fungal development. Our aim was to define the role of Rhacontaining-glycans in the gray mold disease caused by the necrotrophic fungus B. cinerea. The research was built on the discovery of two genes, Bcdhand bcer, that are involved in formation of UDP-KDG and UDP-Rha, two UD
