Yeast diversity in North Carolina Duke Forest.

Yeasts have a major impact on human, plant, and animal health. However, little is known about their diversity, ecology, and distribution in natural ecosystems. The objective of this research was to explore yeast diversity and distribution in different soil horizons in the Duke Forest, NC. Soils samples were diluted and yeast colonies were isolated in peptone-yeast-glucose (PYG) and Malt Extract Agar (MEA) media at 25°C and 35 °C. A total of 66 pure cultures were obtained, extracted, and sequenced using the ITS, LSU, and SSU rRNA regions. Sixty-five percent of yeast isolates belong to the Basidiomycota and 35% belong to Ascomycota. Sporidioboales and Saccharomycetales were the dominant orders and the most abundant taxa were represented by Rhodotorula, Cryptococcus, Trichosporon, Sporidiobolus, and Saccharomyces. Yeast distribution on different soil horizons will be compared to Illumina data obtained from the same soils.
