Postdoctoral Research Fellowship in Microbial Biology for FY2001

这一行动为2001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。研究和培训计划的题目是“苯甲酸降解反硝化细菌和环境样品的遗传多样性”。“16 S rRNA，亚硝酸盐还原酶和苯甲酰辅酶A还原酶的遗传多样性的细菌能够降解苯甲酸盐在酸化条件下，正在研究细菌纯培养物从污染的垃圾填埋场的河口沉积物分离。此外，直接从同一沉积物中提取DNA，构建环境DNA克隆文库（宏基因组文库），以连接环境中涉及苯甲酸盐降解和反硝化的16 S rRNA基因和功能基因的不同类型的遗传信息。

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 "Genetic Diversity in Benzoate Degrading Denitrifying Bacteria and Environmental Samples." Genetic diversity of 16S rRNA, nitrite reductase, and benzoyl-CoA reductase in bacteria capable of degrading benzoate under denitrifying conditions are being investigated with bacterial pure cultures isolated from estuarine sediments of a contaminated landfill site. In addition, DNAs will be extracted directly from the same sediment and environmental DNA clonal libraries (metagenome library) will be constructed to link the different kind of genetic information obtained from 16S rRNA genes and functional genes involved in benzoate degradation and denitrification in the environment.
