Korea produces approximately 26,000 tons of F. velutipes annually, accounting for 17% of its total mushroom production and generating export revenues of about 126 million USD. However, recent detection of Listeria monocytogenes in F. velutipes has led to product recalls and import restrictions in major markets, including the United States, thereby threatening export competitiveness. L. monocytogenes is a psychrotrophic foodborne pathogen capable of surviving and proliferating at low temperatures, causing severe diseases such as meningitis and sepsis in immunocompromised individuals, and miscarriage or fetal death in pregnant women. This study evaluated the antibacterial efficacy of peracetic acid (PAA) among several disinfectants for controlling Listeria contamination. Treatment with 80 ppm PAA once daily or once every two days effectively inhibited Listeria growth on F. velutipes surfaces without affecting mushroom fresh weight or marketability. Furthermore, PAA treatment suppressed not only Listeria but also other pathogenic microorganisms, suggesting improved overall microbial safety. PAA decomposes into water and oxygen, producing no harmful residues, and is approved for organic food production. Its ease of field application further enhances practicality. These findings indicate that PAA is an effective, eco-friendly method for controlling L. monocytogenes contamination in F. velutipes, and its implementation could strengthen the microbiological safety and export stability of Korean mushrooms in global markets.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"54 1","pages":"47-56"},"PeriodicalIF":2.0,"publicationDate":"2025-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12777843/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145934277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used a culture-based approach to characterize the diversity and community structure of endophytic fungi associated with Sargassum thunbergii at five coastal sites on Jeju Island and to examine their relationships with marine environmental factors. Based on isolated and identified strains, we compared among-site community differences and links to environmental variables. In total, 235 isolates representing 94 species across 54 genera were obtained, with Ascomycota comprising 97.9% of all isolates. Community composition differed markedly by site, with high prevalence of several genera, including Didymella and Neocosmospora. α-diversity was higher at western sites (Gosan, Hyeopjae) and lower at northeastern sites (Gimnyeong, Onpyeong), and β-diversity analyses also separated communities among sites. Ordination and constrained analyses identified mean monthly water temperature and dissolved oxygen as the environmental factors most closely associated with community variation. Notably, Neocosmospora solani occurred at all sites, whereas many species were restricted to single locations. These findings are consistent with the idea that the physicochemical characteristics of Jeju's coastal waters may contribute to regional differences in S. thunbergii endophyte communities. This work provides a baseline for understanding alga-fungus interactions around Jeju and highlights the potential of endophyte diversity as a sensitive indicator of coastal environmental change.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"54 1","pages":"38-46"},"PeriodicalIF":2.0,"publicationDate":"2025-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12875103/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146143016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their metabolic adaptations to dynamic, nutrient-rich coastal upwelling environments remain scarcely known. The aim of our research is to contribute to the understanding of the ecological and biogeochemical roles of marine fungi in upwelling systems. To this end, we investigated the metabolic responses of three fungal strains (Sarocladium sp., Penicillium sp., and Fusarium sp.) isolated from the coastal upwelling off central-south Chile. The growth and respiration rates of these marine fungi were comprehensively evaluated using a diverse array of substrates, including glucose, cellobiose, sucrose, glycogen, asparagine, alanine, and glycine. The highest respiration rates were consistently recorded with glycogen, with no significant differences observed among species. Glucose yielded higher respiration rates in Sarocladium sp., and sucrose stimulated greater respiration in Penicillium sp. Phenotype microarrays were used to evaluate mycelium growth on various organic and inorganic nitrogen, phosphorus, and sulfur substrates. All three species exhibited high utilization indices for all substrate types, with organic components promoting the greatest growth. l-Amino acids were the preferred nitrogen sources. Adenosine and guanosine were the primary sources of phosphorus, while cysteine and methionine were the main sources of sulfur necessary for growth. Based on these species' preferred substrates for growth and respiration, we offer new insights into the previously underexplored ecological roles of these fungi in the degradation of marine organic matter and biogeochemical cycling in upwelling ecosystems.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"54 1","pages":"1-14"},"PeriodicalIF":2.5,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12697269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145757116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bioethanol, a renewable fuel derived from biomass, represents a promising alternative, particularly in tropical regions. Yeasts, key agents in ethanol fermentation, have attracted substantial attention for their ability to convert sugars into ethanol. However, the commonly used mesophilic yeast Saccharomyces cerevisiae is temperature-sensitive, limiting its effectiveness in tropical climates. Tropical countries such as Indonesia, Thailand, Vietnam, and Laos, harbor abundant non-conventional and thermotolerant yeast species. These yeasts offer multiple advantages, including reduced contamination risk, lower cooling requirements, and decreased production costs. Moreover, they can utilize complex substrates, such as sucrose, starch, xylose, and lignocellulose biomass, while tolerating high temperatures, ethanol stress, pH fluctuations, and various inhibitors. This review highlights the diversity, physiological traits, and dual industrial potential of thermotolerant and non-conventional yeasts isolated from tropical environments. These yeasts demonstrate robust substrate utilization (including pentoses), high-temperature tolerance, and resilience under stress, positioning them as promising candidates for second-generation bioethanol production as well as for producing value-added aroma compounds.

In Aspergillus fumigatus, a major fungal pathogen, the HLH transcription factor encoded by the AfudrnA gene plays a critical role in the organism's asexual reproductive cycle. This study provides a comprehensive analysis of AfudrnA and its function in conidiation, a key asexual reproductive process. Through targeted deletion of AfudrnA, we observed a dramatic reduction in conidia production, leading to an aconidial phenotype, which suggests that AfudrnA is indispensable for conidiation in A. fumigatus. The deletion mutants, however, showed no significant changes in growth rate or sensitivity to antifungal agents, indicating that AfudrnA specifically influences conidiation rather than general growth or stress responses. To confirm the role of AfudrnA, we reintroduced the gene into the deletion mutants, which restored normal conidiation, further underscoring its essential role in the process. Moreover, expression analysis revealed that AfudrnA is highly expressed during the early stages of conidiation, with transcript levels peaking 6 h after induction of asexual development. Interestingly, the deletion of AfudrnA also led to a significant downregulation of brlA, a key regulator of conidiation, highlighting a potential regulatory interaction between these two factors. These findings elucidate the critical role of AfudrnA in the conidiation of A. fumigatus and contribute to our understanding of the molecular mechanisms governing asexual reproduction in filamentous fungi.
