A monoclonal antibody (MAb; MAb 6B3) which reacts specifically with a cell wall antigen found in all strains or isolates of Candida krusei was developed. MAb 6B3 was extensively tested by immunofluorescence assay for cross-reaction with many Candida, Cryptococcus, Saccharomyces, Trichosporon, and Rhodotorula species and was found to react only with the species C. krusei. The specific epitope is...

A simple medium was developed, using esculin as the substrate, for the isolation and identification of Cryptococcus neoformans. C. neoformans produced a brown-black pigment on the medium; all other yeasts produced no pigment or were light yellow. Esculin is beta-glucose-6,7-dihydroxycoumarin. C. neoformans produced pigment because the 6,7-dihydroxycoumarin component of the esculin molecule was ...

Ilość szkodliwych ksenobiotyków w ekosystemach nieustannie się zwiększa, ze względu na dużą dostępność i wykorzystanie detergentów, pestycydów, farmaceutyków, rozpuszczalników czy ropy naftowej. Takie substancje chemiczne jak fenol, monocykliczne węglowodory aromatyczne, policykliczne alifatyczne oraz związki fosfonoorganiczne są wyjątkowo trwałe niskich temperaturach zwiększoną gęstość mniejsz...

صخلملا A total of 48 fresh water fishes, belonging to four species of the family Cyprinidae (Capoeta trutta, Chalcalburnus mossulensis, Cyprinion macrostomum and Leuciscus lepidus) were collected from Darbandikhan lake, southwest Sulaimaniya city, Kurdistan region, in the north of Iraq, from March to the end of July 2008. The inspection of gills revealed the infection of these fishes with four ...

This review gives an overview of different yeast strains and enzyme classes involved in yeast whole-cell biotransformations. A focus was put on the synthesis of compounds for fine chemical and API (= active pharmaceutical ingredient) production employing single or only few-step enzymatic reactions. Accounting for recent success stories in metabolic engineering, the construction and use of synth...

26 The diversity of culturable yeasts at deep-sea hydrothermal sites has been investigated and 27 raises emerging hints regarding interactions with endemic fauna. Samples were collected 28 during diverse oceanographic cruises at Mid-Atlantic Ridge, South Pacific Basins and East 29 Pacific Rise. A culture collection of thirty-two isolates mostly associated with animals was 30 performed. The phyl...

The survival of fungi in Antarctica is a consequence both ecological selection and evolutionary adaptation expressed at the physiological, metabolic, structural, genetic levels. study biological diversity Antarctic micromycetes will help us to better understand pathways fungal dispersal biosphere, as well broaden our understanding their role extreme ecosystems. In addition, habitats are promisi...

The aim of this study was to evaluate the efficacy of five antiseptics, three surface disinfectants and UV radiation against a wide range of clinical and environmental yeast isolates. Their efficacy against pure cultures, yeast mixtures and biofilms (prepared by culturing yeasts in Sabouraud broth containing a final concentration of 8% glucose) was tested. Three clinical isolates of Candida alb...
