Postdoctoral Research Fellowship in Microbial Biology for FY 2002

这一行动为2002财政年度NSF微生物生物学博士后奖学金提供资金。 该研究金支持关于原生动物、微藻、真菌、古菌、细菌和病毒物种的基础生物学的培训和研究，这些物种通常不被视为模式生物。此外，它为最近的博士生提供了机会，以获得微生物生物学方面的额外培训，在既定科学家的赞助下获得研究经验，并拓宽他/她的科学视野，超越本科和研究生培训期间的研究经验。这些奖学金还旨在帮助新科学家指导他们的研究工作，跨越传统学科，并利用独特的研究资源，地点和设施，包括外国地点。研究和培训计划的标题是"微生物呼吸性砷酸盐还原的分子特征：类金属还原酶基因的多样性和环境表达。“微生物呼吸减少砷酸盐可以显着改变砷在环境中的流动性和毒性。 关于砷呼吸的分子机制知之甚少。 本研究的研究目标是确定各种物种中参与砷酸盐呼吸的基因，包括硫杆菌和希瓦氏菌菌株，并测量污染场地中的砷酸盐呼吸活性。

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.
