Postdoctoral Research Fellowship in Microbial Biology for FY2001

本行动资助2001年度美国国家科学基金会微生物生物学博士后奖学金。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/她的科学视野。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“从永久冰层覆盖的南极湖泊中提取微生物亚硝酸盐还原酶基因的分子特征”。邦尼湖是一个永久被冰覆盖的、化学分层的南极湖泊，它的不同寻常之处在于，反硝化作用发生在东部的深层缺氧水域，而不是西叶。本项目的目的是比较微生物反硝化基因（亚硝酸盐还原酶）在两叶中的分布、多样性和表达，试图解释这一谜团。

This action funds an NSF Postdoctoral Fellowship in Microbial Biology for FY2001. 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 a recent doctoral recipients to obtain additional training in microbial biology, to gain research experience under the sponsorship of established scientists, and to broaden his/her 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 "Molecular characterization of microbial nitrite reductase genes from a permanently ice covered Antarctic lake." Lake Bonney is a permanently ice-covered, chemically-stratified Antarctic lake that is unusual in that denitrification occurs in the deep anoxic waters of the east but not the west lobe. The goal of this project is to compare the distribution, diversity, and expression of denitrification genes (nitrite reductase) from microorganisms in the two lobes in an attempt to explain this mystery.
