EXPLORATORY RESEARCH ON ARCTIC MICROBIAL DIVERSITY

[02:14 . 23] epstein这个项目是对格陵兰岛两个特定地点北极沉积物微生物多样性的探索性研究。这项工作将在实地和实验室进行，以调查海洋沉积物原核生物的分子多样性。利用总DNA提取物和16S rRNA方法，pi将对实验地点沉积物中发现的古细菌和细菌进行表征。-研究海洋沉积物原生生物的分子多样性。他们将在实验地点表征嗜冷和耐冷微真核生物的遗传（18S rRNA和其他基因）多样性。-详细探索一种特定的海洋沉积物原生生物，纤毛原生动物的形态和遗传多样性。他们将寻找隐藏的嗜冷物种，这些物种可能仍然未被识别或被错误识别，因为它们的形态与温带地区的近亲相似。这一探索性项目将为未来对北极沉积物微生物的生态学、进化、基因组学和生物技术潜力的大规模研究奠定基础。

0214231EpsteinThe project is exploratory research on microbial diversity of Arctic sediments at two specific locations in Greenland. The effort will go to the field and work in the laboratory to- Investigate molecular diversity of marine sediment prokaryotes. Using total DNA extracts and 16S rRNA approach the PIs will characterize the Archaea and Bacteria found in the sediments at the experimental sites.- Examine molecular diversity of marine sediment Protista. They will characterize the genetic (18S rRNA and other genes) diversity of psychrophilic and psychrotolerant microeukaryotes at the experimental sites.- Explore in detail morphological and genetic diversity of one specific group of marine sediment protists, ciliated Protozoa. They will be looking for cryptic psychrophilic species that may remain un- or misudentified because of their morphological similarity to their relatives from the temperate areas.This exploratory project will lay the ground for the future large-scale research on ecology, evolution, genomics, and biotechnological potential of microorganisms from Arctic sediments.
