Postdoctoral Research Fellowship in Microbial Biology for FY 2002

这一行动为NSF 2002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，它还为最近的博士获得者提供了获得微生物生物学方面的额外培训的机会，在知名科学家的赞助下获得研究经验，并在本科生和研究生培训期间拓宽其科学视野，超越研究经验。这些奖学金还旨在帮助新科学家引导他们的研究工作跨越传统的学科界限，并利用独特的研究资源、地点和设施，包括外国地点。这项研究和培训计划题为《微生物呼吸砷还原的分子特征：类金属还原酶基因的多样性和环境表达》。微生物呼吸砷酸盐还原可以显著改变砷在环境中的移动性和毒性。人们对砷呼吸的分子机制知之甚少。这项研究的研究目标是在包括硫磺螺杆菌和希瓦氏菌在内的各种物种中识别参与砷酸盐呼吸的基因，并测量受污染地点的砷酸盐呼吸活性。

This action funds an NSF Postdoctoral Fellowship in Microbial Biology for FY2002. 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 respiratory arsenate reduction: diversity and environmental expression of metalloid reductase genes." Microbial respiratory arsenate reduction can significantly alter the mobility and toxicity of arsenic in the environment. Little is known about the molecular mechanisms for arsenic respiration. The research goals of this research are to identify genes involved in arsenate respiration in a variety of species, including Sulfurospirillum and Shewanella strains, and measure arsenate respiratory activity in contaminated sites.
