Postdoctoral Research Fellowship in Microbial Biology for FY 2004

这一行动为NSF 2004财年微生物生物学博士后奖学金提供了资金。该奖学金支持关于原生动物、微藻、真菌、古生物、细菌和病毒物种的基本生物学的培训和研究，这些物种通常不被认为是模式生物。此外，它还为新近获得博士学位的人提供了在微生物生物学方面获得额外培训的机会，在知名科学家的赞助下获得研究经验，并在本科和研究生培训期间拓宽他们的科学视野，超越研究经验。这些奖学金的进一步设计是为了帮助新科学家引导他们的研究工作跨越传统的学科界限，并利用包括外国地点在内的独特的研究资源、地点和设施。研究和培训计划的标题是“使用分子工具评估河口的固氮”。这项研究试图了解固氮菌如何应对不断增加的氮负荷。它探索了微生物层面上对氮气加工的基本控制。一套分子工具，包括克隆文库的构建，DGGE和RT-PCR正在被用来解决与固氮菌在温带盐沼和海草床的氮循环中所起作用有关的问题。

This action funds an NSF Postdoctoral Fellowship in Microbial biology for FY2004. The fellowship supports training and research on the basic biology of protozoan, microalgal, fungal, archaeal, bacterial and viral species that are not generally considered to be model organisms. Further, it provides opportunities for recent doctoral recipients to obtain additional training in microbial biology, to gain research experience under the sponsorship of established scientists, and to broaden their scientific horizons beyond the research experiences during the undergraduate and graduate training. These fellowships are further designed to assist new scientists to direct their research efforts across traditional disciplinary lines and to avail themselves of unique research resources, sites, and facilities, including foreign locations.The research and training plan is entitled "Assessing nitrogen fixation in estuaries using molecular tools." This research seeks to understand how nitrogen-fixing bacteria respond to increasing nitrogen loads. It explores the fundamental controls on nitrogen processing at the microbial level. A suite of molecular tools including construction of clone libraries, DGGE, and RT-PCR are being used to address questions that relate to the role nitrogen fixing bacteria play in the nitrogen cycling of temperate salt marshes and sea grass beds.
