Lumping kinetics models were built for the biological treatment of ABE (acetone-butanol-ethanol) fermentation wastewater by oleaginous yeast Trichosporon cutaneum with different fermentation temperatures. Compared with high temperature (33°C, 306 K) and low temperature (23°C, 296 K), medium temperature (28°C, 301 K) was beneficial for the cell growth and COD degradation during the early stage of fermentation but the final yeast biomass and COD removal were influenced little. By lumping method, the materials in the bioconversion network were divided into five lumps (COD, lipid, polysaccharide, other intracellular products, other extracellular products), and the nine rate constants (k1-k9) for the models can well explain the bioconversion laws...

Limiting nitrogen supply has been routinely used as the master regulator to direct lipid biosynthesis. However, this strategy does not work with nitrogen-rich substrates, such as Jerusalem artichoke (JA), a fructose-based biomass, while it is difficult to obtain a high carbon-to-nitrogen (C/N) molar ratio. In this study, an alternative strategy to promote lipid accumulation by the oleaginous yeast Trichosporon fermentans CICC 1368 was developed by limiting phosphorous supply, and this strategy was implemented with JA hydrolysate as substrate...

Ciprofloxacin (CIP) is one of most used quinolone antibiotics detected frequently in agricultural soils and vegetables. In the present study, variations in microbial community and CIP removal in rhizospheric soils between two cultivars of Brassica parachinensis L. that accumulate higher and lower CIP (Sijiu and Cutai, respectively) were investigated under CIP stress (0mg/kg in CK, 2.94mg/kg in T1, and 67.11mg/kg in T2). The removal rates of CIP in rhizospheric soils of cultivar Sijiu were higher than those of cultivar Cutai, with a significant difference in T2 (48...

BACKGROUND: Microbial oil is one important bio-product for its important function in energy, chemical, and food industry. Finding suitable substrates is one key issue for its industrial application. Both hydrophilic and hydrophobic substrates can be utilized by oleaginous microorganisms with two different bio-pathways ("de novo" lipid fermentation and "ex novo" lipid fermentation). To date, most of the research on lipid fermentation has focused mainly on only one fermentation pathway and little work was carried out on both "de novo" and "ex novo" lipid fermentation simultaneously; thus, the advantages of both lipid fermentation cannot be fulfilled comprehensively...

The Trichosporon species are yeast-like opportunistic pathogens in immunocompromised patients. Trichosporon asahii infections have been reported in pediatric bone marrow transplant (BMT) patients. However, its incidence is low in the adult literature. A 52-year-old Chinese woman who was diagnosed with acute myeloid leukemia received induction chemotherapy and underwent allogenic bone marrow transplant, which was complicated by a relapse and required salvage chemotherapy. She developed persistent non-neutropenic fever secondary to presumed hepatosplenic candidiasis...

Several pathogenic fungi and cases related to Japanese medical mycologists were reviewed. Trichosporon inkin (as Sarcinomyces inkin) was reported as a pathogen of scrotal lesion by Oho in 1921, and Trichosporon asahii was isolated from generalized keratotic lesions in 1922 by Akagi in Japan. They were once included in Trichophyton beigelii, but then based on revision using DNA molecular technology, were returned to their original names.Microsporum ferrugineum was reported by Ota as a causative dermatophyte of tinea capitis in Japan and surrounding areas...

A 4-year-old girl with severe aplastic anemia and 2 previous failed T-depleted haploidentical peripheral blood stem cell transplants developed persistent neutropenic fever and multiple erythematous maculopapular rashes 2 days after her third T-replete haploidentical bone marrow transplant. Skin biopsy confirmed the diagnosis of Trichosporon asahii infection. She was on caspofungin prophylaxis which is not effective against Trichosporon. A high index of suspicion, prompt investigation, and appropriate treatment with voriconazole for 4 months was instrumental in controlling the infection and she remains well presently 9 months posttransplant with full donor chimerism and free from infection...

"Paracoccidioidomycosis ceti" is a rare zoonotic fungal infection affecting dolphins and is endemic worldwide. The causative agents are Paracoccidioides species; however, it is impossible to isolate the fungal species. We isolated Trichosporon asteroides from multifocal, irregularly raised skin lesions on a female bottlenose dolphin (Tursiops truncatus) captured off coast of Japan, which was suspected to have "paracoccidioidomycosis ceti." An abundance of round, yeast-like cells was detected in a potassium hydroxide direct-mount specimen of the skin samples; however, nested PCR targeting the partial sequence of 43-kDa glycoprotein-coding gene correspondent to Paracoccidioides sp...

Trichosporon species are relevant etiologic agents of hospital-acquired infections. High mortality rates are attributed to Trichosporon deep-seated infections in immunocompromised individuals, being fast and accurate species identification relevant for hasting the best-targeted therapy. Recently, Trichosporon taxonomy has been re-assessed and three genera have been proposed for the pathogenic species: Trichosporon, Cutaneotrichosporon and Apiotrichum Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has replaced old phenotypic methods for microorganism's identification in clinical laboratories, but spectral profile databases have to be evaluated and improved for optimal species identification performance...

BACKGROUND: Poultry farming and consumption of poultry (Gallus gallus domesticus) meat and eggs are common gastronomical practices worldwide. Till now, a detailed understanding about the gut colonisation of Gallus gallus domesticus by yeasts and their virulence properties and drug resistance patterns in available literature remain sparse. This study was undertaken to explore this prevalent issue. RESULTS: A total of 103 specimens of fresh droppings of broiler chickens (commercial G domesticus) and domesticated chickens (domesticated G domesticus) were collected from the breeding sites...

Fusarium are ubiquitous hyalohyphomycoses, usually encountered in the soil. They are the second unusual fungal pathogens after the Trichosporon. Intertrigo Fusarium sp. is a rare achievement. We report a case of intertrigos interorteils in an immunocompetent 45years old and a same case associated with a total onychodystrophy in an immunocompromised 75year-old. Laboratory diagnosis has found Fusarium solani confirmed with the positivity of a pure culture twice. Good progress was noted with terbinafine treatment...

In the co-culture of Staphylococcus epidermidis and Trichosporon asahii, a fungal pathogen, it was observed that live S. epidermidis inhibited the growth of T. asahii. Soluble active anti-T. asahii substances were speculated to be produced by S. epidermidis in culture medium. Using (1)H- and (13)C-NMR spectra and electron ionization-high resolution mass spectrometry (HR-negative-FAB-MS), we separated the active molecule and identified it as lactic acid. Commercially available L-lactic acid and D-lactic acid inhibited the growth of T...

The influence of cultural conditions on lipid production was investigated in two species, Trichosporon oleaginosus and Rhodosporidium azoricum. We showed that nitrogen limitation is not the main factor triggering the mechanism of lipid accumulation in T. oleaginosus. Moreover, a scarce availability of oxygen negatively affected lipid synthesis to a lesser extent in T. oleaginosus than in R. azoricum. This highlights how the importance of controlling fermentation parameters is strictly linked to the yeast species employed...

  Oleaginous yeast Trichosporon oleaginosus was studied for lipid production using municipal sludge with or without fortification of crude glycerol in a 15-L fermenter. The maximum lipid content (concentration) was 32.0% w/w (9.35 g/L), 33.6% (10.13 g/L), 33.3% (9.13 g/L), and 33.1% (9.03 g/L) w/w with the addition of 25, 50, 100, and 150 g/L glycerol, respectively. Glycerol concentration had little effect on lipid accumulation. However, glycerol concentration substantially affected increase of biomass concentration and cell count...

Fungi of the genus Trichosporon are increasingly recognized as causative agents of superficial and invasive fungal disease in humans. Although most species are considered commensals of the human skin and gastrointestinal tract, these basidiomycetes are an increasing cause of fungal disease among immunocompromised hosts, such as hematological patients and solid organ transplant recipients. The initiation of commensal or pathogenic programs by Trichosporon spp. involves the adaptation to the host microenvironment and its immune system...

Magnusiomyces capitatus (previously known as Geotrichum capitatum or Blastoschizomyces capitatus or Trichosporon capitatum) is a rare cause of fungal infection in immunocompromised patients. Most of these cases (87%) have been reported from the Mediterranean region, as it is extremely rare to recognize it in other regions. Here we report a first case of disseminated M. capitatus infection in Slovakia. The patient - 19 year old woman with myelodysplastic syndrome was diagnosed with M. capitatus fungemia after allogeneic stem cell transplantation...
