Chemical treatments are an alternative approach that is also employed in some regions. Mycelial growth and density were analyzed in vitro by capturing daily photographs using a digital camera, with sterilized substrate serving as the control treatment. Our findings revealed that both fermented and sterilized substrates had similar growth patterns, although fermented treatment required a longer incubation time for full substrate colonization. Mycelium in fermented substrate had a denser structure compared to sterilized treatment, reflecting the interactions with the naturally-present microorganisms within the substrate. Conversely, mycelium in sterilized treatment exhibited faster substrate colonization times but had a less dense mycelial structure. Yeast and bacterial colonies were present throughout the fermentation process and 7 days after P. ostreatus mycelium inoculation, indicating active microbial communities during colonization. An initial decrease in CFU on the 3rd day, followed by an increase by the 7th day, suggests a shift toward anaerobic and facultative microorganisms due to oxygen depletion during fermentation. Mold colonies disappeared by the end of fermentation. Despite the complex interactions between yeast, bacteria, and P. ostreatus mycelium, the naturally-present microorganisms in the substrate appear to have at least neutral effects, enabling mycelial growth.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 2","pages":"214-224"},"PeriodicalIF":1.6,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11912283/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649722","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}

Previously, we utilized A. rabiei as a heterologous host to produce a lichen-derived polyketide with anticancer activities. This study aimed to establish A. rabiei as a sustainable biorefinery for production of biologically active compounds through two objectives: optimizing culture conditions on agricultural waste substrates for polyketide production and generating a clean host using the Cre-loxP system for reusable antibiotic resistance markers. We found that soy hull is the most effective substrate among lignocellulosic materials. Neither light nor the addition of extra divalent cations were required for solanapyrone production in A. rabiei. Production of solanapyrones peaked 18 days after culture on soy hull pellets. To generate a clean host, we deleted the pks1 gene, involved in melanin biosynthesis, and the sol1 gene, responsible for solanapyrone production. Antibiotic resistance markers used in genetic transformation were recycled by establishing a Cre-loxP system in A. rabiei. In this system, Cre recombinase was expressed under the control of a promoter inducible during sporulation to mitigate the cytotoxicity of Cre. Here, we set the groundwork for developing A. rabiei as an environmentally-friendly biorefinery by generating a clean host with a Cre-loxP marker recycling system and optimizing growth conditions with soy hull pellets.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 2","pages":"225-235"},"PeriodicalIF":1.6,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12010432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144013735","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}

The annual number of C. albicans isolates increased by 161.1% in 2019 and 136.7% in 2022 compared with that in the previous year. The mean age of patients from whom C. albicans was isolated was 65.8 years, with 51.8% patients being aged 60-79 years. The number of isolates was higher in male patients than in female patients (male-to-female ratio: 1.4:1). Of the isolates, 6.6% were resistant to flucytosine and 4.5% were resistant to voriconazole, whereas all isolates were susceptible to caspofungin and micafungin.

While cAMP-dependent signaling has long been considered central to hyphal growth, recent multi-omics studies show that cAMP-independent mechanisms also drive morphological changes. Basal PKA activity, cyclin-dependent kinases (e.g., Cdc28), and other regulators can promote shape-shifting even without classical cAMP pathways. In addition, N-acetylglucosamine (GlcNAc) acts as a potent signal that induces hyphal growth independently of its metabolic role, directly connecting environmental cues to morphological states. By integrating transcriptomic, proteomic, and phosphoproteomic data, this review exposes the intricate networks controlling C. albicans morphogenesis. A clearer understanding of these complex regulatory circuits lays the groundwork for future studies that employ advanced multi-omics analyses. Such approaches will help elucidate how these pathways converge, how they respond to changing environments, and how they might be harnessed or disrupted to influence fungal behavior.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 2","pages":"250-257"},"PeriodicalIF":1.6,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11912286/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649751","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}

The results indicated that a temperature of 30 °C consistently yielded the highest numbers of zoospores across all incubation periods. Applying the same temperature (30 °C) and all incubation periods to other isolates (CCp03, CCp04, CCp05, HSv10, and KACC 40156) also resulted in higher numbers of zoospores regardless of incubation times compared with that under the control condition (25 °C and 2 days). Further virulence tests of isolate HSv05 revealed that high concentrations of zoospores (5 × 102 - 105 zoospores/ml) induced severe rot symptoms; however, a low concentration of 102 zoospores/ml produced only considerably weak symptoms on inoculated potato tubers. No symptoms appeared in tubers inoculated with 0 (uninoculated control) or 101 zoospores/ml.
