Minus 80 freezer

申请零下80度的冷冻室。两位申请人的研究项目都涉及植物与微生物的相互作用，在这两种情况下，都需要将收集的微生物冷冻在极低的温度下。两位申请人都从事豆类固氮工作，需要收集根瘤菌，一位申请人还从事植物生长促进根瘤菌和细菌素的工作，两者都需要额外的菌株收集。最后，在某些情况下，申请人从处理和对照植物的组织中分离代谢物，这可能需要-80℃的冷冻，直到可以完成分析。申请申请资金购买Forma 904型超低温立式单门冷冻机。申请人在研究成果和培养高素质人才方面非常有成效。

A minus 80 C freezer is applied for.  The research programs of both applicants involve plant-microbe interactions, and in both cases there is a need to keep collections of microbes frozen at very low temperatures.  Both applicants conduct work in legume nitrogen fixation, requiring collections of rhizobia, and one also does work with plant growth promoting rhizobacteria and bacteriocins, both requiring additional collections of strains.  Finally, in some cases the applicants isolate metabolites from the tissues of treated and control plants and this may require -80 C freezing until such time as the analyses can be completed.  The applications are requesting funds to purchase a Forma Model 904 ultra low temperature upright single door freezer.  The applicants are very productive in terms of research output and training of highly qualified personnel.
