Postdoctoral Research Fellowship in Microbial Biology for FY 2004

该行动为2004财年美国国家科学基金会微生物生物学博士后奖学金提供资金。该奖学金支持一般不被认为是模式生物的原生动物、微藻、真菌、古细菌、细菌和病毒物种的基本生物学培训和研究。此外，它为最近的博士学位获得者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。这些研究金的进一步目的是帮助新科学家指导他们的研究工作跨越传统的学科界线，并利用独特的研究资源、地点和设施，包括国外的地点。这项研究和培训计划的标题是“利用分子工具评估河口的固氮作用”。本研究旨在了解固氮细菌如何对增加的氮负荷作出反应。它探讨了微生物水平上氮处理的基本控制。包括克隆文库构建、DGGE和RT-PCR在内的一系列分子工具正在被用于解决与固氮细菌在温带盐沼和海草床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.
