Diversity, Diversity and Tolerance profile of Wild Yeasts from Natural Forests

In a natural forest in southwest Ethiopia, the study investigates the diversity and distribution of wild yeast species in the rhizosphere soil and plant surfaces. With high rates of yeast isolation from tree bark, it exposes a variety of yeast genera. Seasonal differences in yeast abundance were also discovered by the study; spring and summer demonstrated significant positive relationships. The discovery of stress-tolerant yeast species showed how adaptable they are to harsh environments. The study emphasizes the potential of stress-tolerant yeasts for biotechnological applications as well as the significance of natural forests as repositories of microbial diversity.

本研究以埃塞俄比亚西南部的天然林为研究区域，针对根际土壤（rhizosphere soil）与植物表面的野生酵母菌种（wild yeast species）的多样性与分布特征展开调查。该研究从树皮中以较高的酵母分离率获得菌株，揭示了多个酵母属（yeast genera）类群。此外，研究还发现酵母丰度存在显著季节差异：春季与夏季的酵母丰度呈显著正相关。本次发现的耐胁迫酵母菌种（stress-tolerant yeast species），展现出其对极端严苛环境的良好适应性。本研究既强调了耐胁迫酵母在生物技术应用（biotechnological applications）中的潜在价值，同时也凸显了天然林作为微生物多样性（microbial diversity）储存库的重要意义。
