The comparative analysis of different taxonomic groups of microorganisms isolated from dark chernozem soils under different agricultures (alfalfa, melilot, sainfoin, soybean, rapeseed) at Almaty region of Kazakhstan was conducted. It was shown that the greatest number of micromycetes was typical to the soil planted with alfalfa and canola. Species diversity of micromycetes markedly decreases as...

Yeast communities associated with sugarcane leaves, stems and rhizosphere during different phases of plant development were studied near Campos, in Rio de Janeiro, Brazil. Atmospheric temperature, soil granulometry and pH, and sugar cane juice degree Brix and pH were determined. Yeast communities associated with sugarcane were obtained after cellular extraction by shaking, blending and shaking ...

The aims of this work was to characterise indigenous Saccharomyces cerevisiae strains in the naturally fermented juice of grape varieties Cabernet Sauvignon, Grenache, Tempranillo, Sauvignon Blanc and Verdejo used in the São Francisco River Valley, northeastern Brazil. In this study, 155 S. cerevisiae and 60 non-Saccharomyces yeasts were isolated and identified using physiological tests and seq...

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 ...

The effect of nine different pesticides on the growth of yeasts isolated from the leaves of fruit and forest trees was investigated. Four insecticides (with the active ingredients: thiacloprid, deltamethrin, lambdacyhalothrin, and thiamethoxam) and five fungicides (with the effective substances: bitertanol, kresoxim-methyl, mancozeb, trifloxystrobin, and cupric oxychloride) were tested. The con...

Onychomycosis is a fungal infection of nail, its matrix, and other nail parts which is usually caused by dermatophytes. However number of nail infections due to yeast and nondermatophyte moulds (NDM) is also increasing. Although Candida albicans accounts for most of the cases of onychomycosis caused by yeasts, there has been a change in the epidemiology of Candida infections, characterized by a...

A group of biodegradable alanine-derived gemini quaternary ammonium salts (bromides and chlorides) with various alkyl chains and spacer lengths was tested for anti-adhesive and anti-biofilm activity. The strongest antifungal activity was exhibited by bromides with 10 and 12 carbon atoms within hydrophobic chains (N,N'-bis(1-decyloxy-1-oxopronan-2-yl)-N,N,N',N'-tetramethylpropane-1,3-diammonium ...
