Cocoa butter (CB) extracted from cocoa beans is the main raw material for chocolate production. However, growing chocolate demands and limited CB production has resulted in a shortage of CB supply. CB is mainly composed of three different kinds of triacylglycerols (TAGs), POP (C16:0-C18:1-C16:0), POS (C16:0-C18:1-C18:0), and SOS (C18:0-C18:1-C18:0). The storage lipids of yeasts, mainly TAGs, also contain relative high-level of C16 and C18 fatty acids and might be used as CB-like lipids (CBL). In this study, we cultivated six different yeasts, including one non-oleaginous yeast strain, Saccharomyces cerevisiae CEN...

Trichosporon asahii (T. asahii) is an opportunistic pathogen that can cause life-threatening infections in immunocompromised patients, with high mortality rates up to 80% despite treated with antifungal drugs. The biofilms-forming ability of T. asahii on indwelling medical devices may account for the resistance to antifungal drugs. Berberine (BBR) has been demonstrated to have antifungal activity and synergistic effects in combination with antifungal drugs against pathogenic fungi. In the present study, the in vitro activities of BBR alone or combined with fluconazole (FLC), itraconazole (ITC), voriconazole (VRC), caspofungin (CAS) and amphotericin B (AMB) against planktonic forms and biofilms of 21 clinical T...

The prevalence of fungi in the respiratory tract of cystic fibrosis (CF) patients has risen. However, fungal surveillance is not routinely performed in most clinical centers in the United States, which may lead to an underestimation of the true prevalence of the problem. We conducted a prospective study comparing fungal detection rates for clinically important fungi (CIF) defined as Aspergillus species, Scedosporium species, Trichosporon species, and Exophiala dermatitidis in CF sputum using standard bacterial culture media and selective-fungal culture media, including Sabouraud dextrose agar with gentamicin (SDA), inhibitory mold agar (IMA), and brain-heart infusion agar (BHI) with chloramphenicol and gentamicin...

INTRODUCTION: Non-Candida opportunistic yeasts are emerging causes of bloodstream infection (BSI) in immunocompromised hosts. However, their clinical presentation, management, and outcomes in stem cell transplant (SCT) recipients are not well described. CASE REPORT AND REVIEW: We report the first case to our knowledge of Pseudozyma BSI in a SCT recipient. He had evidence of cutaneous involvement, which has not been previously described in the literature. He became infected while neutropenic and receiving empiric micafungin, which is notable because Pseudozyma is reported to be resistant to echinocandins...

Trichosporon asahii (T. asahii) is the major pathogen of invasive trichosporonosis which occurred mostly in immunocompromised patients. The biofilms formation ability of T. asahii may account for resistance to antifungal drugs and results a high mortality rate. Sertraline, a commonly prescribed antidepressant, has been demonstrated to show in vitro and in vivo antifungal activities against many kinds of pathogenic fungi, especially Cryptococcus species. In the present study, the in vitro activities of sertraline alone or combined with fluconazole, voriconazole, itraconazole, caspofungin and amphotericin B against planktonic forms and biofilms of 21 clinical T...

Trichosporon asahii is a pathogenic basidiomycetous yeast. Individual strains of T. asahii have different colony morphologies. However, it is not clear whether cell surface phenotypes differ among the colony morphologies. Here we characterized the cell surface hydrophobicity and analysed the carbohydrate contents of the cell surface polysaccharides in T. asahii clinical isolates with various colony morphologies. Among the three distinctive colony morphologies obtained from one clinical isolate, the white-type morphology exhibited higher hydrophobicity...
