Dynamics of abundance and diversity of epiphytic yeasts in entomophilic flowers of 28 species of meadow, forest, and cultivated plants throughout their blooming period was determined. The number of yeasts in the flowers was shown to increase gradually during the vegetation period, and reached the maximum during summer-autumn. The total abundance and ratio(More)
Resistance of 14 yeast species belonging to different ecological groups to extensive storage in a dried state was investigated. Pedobiotic yeasts isolated mainly from the soils of humid areas (Cryptococcus podzolicus, Cr. terricola, and Lipomyces starkeyi) were the least resistant. The yeasts associated with the nectar of entomophilous plants (Metschnikowia(More)
Long-term studies of yeast species diversity in the vineyards of the Republic of Dagestan using various isolation techniques and various substrates in the vertical tier dynamics revealed 38 species. The most diverse species complex including ~80% of the isolated species was formed on the berries. A list of 160 yeast species isolated from grapes,(More)
Yeast abundance and species diversity in the latex of rubber tree Hevea brasiliensis (Willd. ex Juss.) Müll. Arg., on its green leaves, and in soil below the plant were studied. The yeasts present in the fresh latex in numbers of up to 5.5 log(CFU/g) were almost exclusively represented by the species Candida heveicola. This species was previously isolated(More)
722 In recent years, numerous studies have dealt with the investigation of the phyllosphere and associated aboveeground plant substrates. They are both of nonn recurrent and monitoring nature and relate to the taxx onomic and ecological features of epiphytic and endoo phytic yeast communities of leaves, flowers, and fruits However, the yeast population of(More)
Yeast abundance and diversity in a mixed forest sod–podzol soil under Impatiens parviflora DC plants was studied in comparison with unimpaired aboriginal herbaceous plants typical of the Central Russian secondary, after-forest meadow. The study was carried out throughout the vegetation period. Standard microbiological plating techniques revealed 36 yeast(More)
Yeast abundance and species diversity in the colonies of Formica aquilonia ants in birch–pine grass forest near Novosibirsk, Russia, were studied. The average yeast number in the anthill material was 103–104 CFU/g, reaching 105 CFU/g in the hatching chambers. Typical litter species (Trichosporon moniliiforme and Cystofilobasidium capitatum) were predominant(More)
High performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) was applied to the comprehensive analysis of the ability of yeast strains to synthesize a plant hormone indole-3-acetic acid (IAA). A total of 124 strains (37 species) of yeasts isolated from various regions and substrates were studied. Testing of IAA production showed(More)
