Nannan Jiang earns Oral Presentation award at ORNL Symposium

On August 18, 2017, the Oak Ridge Postgraduate Association (ORPA) organized its annual research symposium at the Oak Ridge National Laboratory (ORNL), which hosted 30 oral presentations and 88 poster presentations. This year, many members of Frank Löffler’s team had the opportunity to present their work, including Gao Chen, Nannan Jiang, Fadime Kara-Murdoch, and Robert Murdoch. Following the Symposium, Nannan Jiang won 3rd place for best oral presentation, an award presented by keynote speaker Dr. Alan G. Marshall of the Florida State University. Jiang’s talk, entitled “Pathway modification in Geobacter sulfurreducens alleviates corrinoid auxotrophy in Dehalococcoides species and sustains reductive dechlorination”, focused on a project with co-author Dr. Jun Yan to probe corrinoid biosynthesis in obligate anaerobes. Corrinoids are vital cofactors required by all 3 domains of life. For example, Dehalococcoides species depend entirely on corrinoids produced by other microorganisms to degrade the toxic chlorinated solvents found in groundwater.
