Yeasts of Nikitsky Botanical Garden plants

Аннотация

Abundance and taxonomic structure of yeast communities on the surface and in the tissues of various plants of the Nikitsky Botanical Garden was studied. A total of 22 yeast species were isolated, including rare and new species. Yeast numbers on the studied plant substrates were varied within a broad range (8 × 10²‒2.5 × 10⁷ CFU/g), reaching the maximum in Verbascum thapsus flowers, on the surface and inside the fruits of Rubus sp. and Ficus carica. Epiphytic and endophytic yeast communities of Ficus carica fruits were studied in dynamics, from fruit formation until their complete maturation and senescence. Specific properties of the yeast communities of the Nikitsky Botanical Garden plants and the features of the yeast communities from fig fruits are discussed in the paper.
