[Diversity of cultivable yeast in Qilu Lake in winter]
Objective:
To investigate yeasts diversity in Qilu Lake and analyze the influence of environmental factors on yeast diversity.
Methods:
Yeasts were isolated by in-situ cultivation and analyzed for the D1/D2 domain of large subunit (26S) ribosomal DNA and morphological characterization. We analyzed yeast species richness and species distribution in the Qilu Lake.
Results:
In total 321 isolated yeasts were identified to 14 genera and 27 species. Rhodosporidium kratochvilovae and Aureobasidium pullulans were the dominating species in the lake, representing 29.6% and 16.8% of the total strains, respectively. Principal component analysis (PCA) showed that the total phosphorus was an important environmental factor affecting the distribution of Rhodosporidium and the pH affected Cryptococcus yeasts distribution.
Conclusion:
There was a high diversity of yeasts community in the Qilu Lake. Keywords: Qilu Lake, yeast, diversity, environmental factors.
