🌌 Hy-five: Fungal Knowledge in LATAM, Sugar Waste Fermentation, Mushroom Chitosan, Fermented Oils for Cosmetics, Swiss Yeasts

β€” This roundup covers several fungal applications: knowledge dissemination initiatives in Latin America, fermentation of sugar waste using fungi, chitosan extraction from mushrooms, fermented oils for cosmetic products, and yeast research in Switzerland. The specific details of each development are not provided in the excerpt.

JoF, Vol. 12, Pages 347: Analysis of Short-Term Responses to Hypoxia During Stirred-Tank Fermentation in Aspergillus oryzae

β€” Researchers analyzed how Aspergillus oryzae responds to low-oxygen conditions during fermentation in stirred-tank bioreactors over the first six hours. The fungus rapidly adjusted its respiratory chain genes, increased alternative oxidase expression, and upregulated glycolysis to maintain ATP levels while managing a transient spike in reactive oxygen species. Deleting the alternative oxidase gene prolonged oxidative stress, suggesting this pathway helps mitigate hypoxic damage.

JoF, Vol. 12, Pages 346: Soil Fungal Communities Across Contrasting Land-Use Systems in an Intensively Managed Cerrado Landscape

β€” A study of soil fungi across native Cerrado, cover-cropping, and potato monoculture sites in Brazil found no significant differences in fungal community composition or alpha-diversity among the three land-use systems, despite distinct chemical and enzymatic soil properties. The researchers identified 157 shared fungal taxa across sites, including Fusarium, Cladosporium, and Trichoderma, but note their findings are preliminary and call for further investigation into fungal dispersal and long-term agricultural impacts on the Cerrado ecosystem.

JoF, Vol. 12, Pages 340: Deciphering Neutral Ceramidase-Dependent Mechanism of Response to Aromatic Fungicides Stress in Neurospora crassa

β€” A study in Neurospora crassa identified neutral ceramidase as a key enzyme in fungal resistance to aromatic fungicides like carvacrol and cuminaldehyde. The enzyme enhanced stress tolerance by strengthening cell walls, reducing membrane permeability, boosting antioxidant defenses, and accumulating protective compounds. The findings suggest targeting this enzyme could help control pathogenic fungi in agriculture and food preservation.

JoF, Vol. 12, Pages 339: IFUCISTRATEGY: A Spanish Survey on the Management of Invasive Fungal Infection (IFI) in Critically Ill Patients

β€” A Spanish survey of 63 ICU specialists found broad agreement on treating invasive fungal infections in critically ill patients. Most respondents endorsed using galactomannan testing to guide pulmonary aspergillosis treatment, recommended isavuconazole and liposomal amphotericin B for aspergillosis with influenza coinfection, and noted that extracorporeal membrane oxygenation and renal replacement therapies may reduce azole drug levels.

JoF, Vol. 12, Pages 331: Advances in the Control of Plant Fungal Pathogens

β€” Fungal pathogens cause an estimated 30% loss in global agricultural production and are increasingly resistant to chemical fungicides. A review in the Journal of Fungi examines control strategies including biocontrol agents, biofungicides, and molecular biology approaches to develop more sustainable disease-management alternatives in response to regulatory pressures and market demands.

JoF, Vol. 12, Pages 332: Genomic Insights and Antifungal Efficacy of Xenorhabdus budapestensis XH-4 in Combating Soybean Root Rot

β€” Xenorhabdus budapestensis XH-4, a bacterium associated with entomopathogenic nematodes, suppressed the fungal pathogen Fusarium oxysporum in vitro and reduced soybean root rot disease by 75–80% in greenhouse trials, matching chemical fungicide performance. Antifungal activity stems from extracellular metabolites and secondary compounds including fabclavine and putrebactin. The bacterium also boosted plant antioxidant defenses, suggesting a dual mechanism of direct antagonism and induced resistance.

JoF, Vol. 12, Pages 327: From Contact to Stalemate: MAPK-Associated Chemical and Enzymatic Defenses Shape a Stable Barrage in the Co-Culture of Trametes sp. D and Aspergillus niger L14

β€” In co-culture, Trametes sp. D and Aspergillus niger L14 form an antagonistic zone where each fungus produces secondary metabolites that suppress its competitor without harming itself. Transcriptomic and biochemical analyses revealed both fungi activate stress-response pathways, including MAPK signaling, alongside production of cell wall-degrading enzymes and organic acids, suggesting physical contact triggers chemical and enzymatic defenses that maintain a stable competitive stalemate.
