Twenty-five yeast cultures, mainly of human origin, belonging to four pathogenic yeast species--Candida albicans, Candida krusei, Candida parapsilosis, and Candida tropicalis were tested for their sensitivity to ten basidiomycetous and eleven ascomycetous yeast species isolated from the water and soil environments and from tree leaves. The best killer activity among basidiomycetous species was ...

in this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of candida membranifaciens to decrease blue mold on apple. the media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. yeast extract as nitrogen source produced higher bio...

BACKGROUND Absence or severe reduction in the amount of ergosterol in the fungal membrane and its replacement with other sterols have been described as potential antifungal resistance mechanisms in fungi. AIMS AND METHODS The ergosterol content in a collection of 51 clinical yeast isolates, including susceptible and resistant strains to amphotericin B and azoles, was estimated by a simple chr...

Background and Purpose: Catheter-related blood circulation infection is the most dangerous and serious side-effects of vascular catheters, which leads to the enhancement of the costs, mortality, and hospital stay duration, especially in the Intensive Care Unit. Regarding this, the aim of the current study was to identify the prevalence of catheter-induced candidemia in the Tehran Heart Center, ...

Two novel yeast species, Candida aechmeae sp. nov. and Candida vrieseae sp. nov., were isolated from bromeliads in Itapuã Park, Rio Grande do Sul, Brazil. These species are genetically isolated from all other currently recognized ascomycetous yeasts based on their sequence divergence in the D1/D2 domain of the LSU rRNA gene. C. aechmeae sp. nov. is phylogenetically close to Candida ubatubensis,...

the biocontrol activity of two isolates of candida membranifaciens against grey mold of apple fruit caused by botrytis mali and their ability to induce biochemical defense responses in apple tissue were investigated. apple fruit (malus domestica) wounds were inoculated with 50 µl yeast suspension (1 × 107 cfu/ml) of c. membranifaciens followed 4 h later by 20 µl of conidial suspension of b. mal...

In a taxonomic study of yeasts that have been isolated in French Guiana and Thailand, five yeast strains isolated from plants were found to belong to the Yamadazyma clade of Saccharomycotina. On the basis of morphology, physiology and the nucleotide divergence in the D1/D2 domain of the 26S nuclear ribosomal RNA (nrRNA) gene, as well as the internal transcribed spacers (ITS) domain of the nrRNA...

Fungal endophytes are not widely known for their role in bioactive metabolite production and salinity stress alleviation different crop plants. Presently, we investigated the salt (NaCl, KCl, H2SO4) mitigation capabilities of fungal endophyte Candida membranifaciens (FH15) isolated from Euphorbia milii L. The pure culture filtrate (CF) C. revealed siderophore solubilization phosphate, with high...

Experimental research on beetle responses to removal of logging residues following clearcut harvesting in the boreal balsam fir forest of Quebec revealed several abundant rove beetle (Staphylinidae) species potentially important for long-term monitoring. To understand the trophic affiliations of these species in forest ecosystems, it was necessary to analyze their gut contents. We used microsco...
