The mitogen-activated protein kinase (MAPK) Hog1p plays an essential role in the yeast hyperosmotic response. A homolog of the HOG1 gene was isolated from the halophilic black yeast Hortaea werneckii encoding a putative 359 amino acid protein, HwHog1p, with high homology to Saccharomyces cerevisiae Hog1p and to other eukaryotic Hog1p homologs. HwHog1p contains a TGY motif within a protein kinas...
A monophyletic group of black yeast-like fungi containing opportunistic pathogens around Exophiala spinifera is analyzed using sequences of the small-subunit (SSU) and internal transcribed spacer (ITS) domains of ribosomal DNA. The group contains yeast-like and annellidic species (anamorph genus Exophiala) in addition to sympodial taxa (anamorph genera Ramichloridium and Rhinocladiella). The ne...
We report a case of cerebral phaeohyphomycosis due to Wangiella dermaitidis in an immunocompetent adult man. His cerebrospinal fluid (CSF) showed pleocytosis with a high eosinophil count but without peripheral blood eosinophilia. The present case suggested that this black yeast-like fungus should be included when the causes of CSF eosinophilia are considered, even though it is an extremely rare...
micro-organisms such as bacteria, yeasts, molds and algae that accumulate lipid more than 20% of their biomass are called oleaginous. microbial lipid has a lot of similarity to the oil obtained from plants and animals. microbial lipids are renewable sources that can use for different purposes such as biodiesel production. production of oil from yeasts has more advantages than plant’s oil. accor...
abstract background: the disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6g. methods: atotal of 568 iranian soldiers went under study for isolation and identification of yeast speci...
The genus Fonsecaea comprises black yeast-like fungi of clinical relevance, including etiologic agents of chromoblastomycosis and cerebral phaeohyphomycosis. Presence of melanin and assimilation of monoaromatic hydrocarbons and alkylbenzenes have been proposed as virulence factors. Multicopper oxidase (MCO) is a family of enzymes including laccases, ferroxidases and ascorbate oxidases which are...
fuller, in 1989, described probiotic microorganisms as “a live microbial feed supplement,which beneficially affects the host animal, by improving its intestinal microbial balance”.saccharomyces cerevisiae var. boulardii (s.boulardii) is an accurate probiotic yeast idol.the detection and budding of s.boulardiiis firmly related to the impression of healthinessto promote microorganisms from foodst...
endophytes are important resources of bioactive compounds and due to their potential in theproduction of secondary metabolites, they are regarded as a potential reservoir ofbiotechnological applications. in this study, the bioactivity of bacteria and yeasts endophytesresiding in thymus sp. was evaluated. during april to october 2011, symptomless and healthytissues of thymus sp. were collected. ...
BACKGROUND AND OBJECTIVES Synthetic dyes are recalcitrant to degradation and toxic to different organisms. Decolorization of textile wastewaters is one of the major concerns since last decades. Physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. Biological treatments can be more convenient. In the present study, an attempt has been made for de...
This work looks for a better understanding of the biodegradation of xenobiotic azo dyes mediated by yeasts. During a screening program of phenolic acid assimilating capacities it was found that a non-conventional ascomycetous yeast isolate, identified as Candida oleophila, efficiently decolorizes agar plates supplemented with the commercial textile diazo dye Reactive Black 5. Aerobic batch cult...
