2007 plenary speaker, Dr. Sheila David research group

2007 Berea College Research Symposium

The research symposium held each fall the same weekend that the Berea College Trustees visit campus is an opportunity for the students and faculty to share research work with each other as well as these important campus visitors. This has been organized by the science departments in the past but participation is open to all members of the college community. In recent years we have structured the symposium with both talks and poster presentations as well as a plenary session.
The symposium for Fall 2007 was held on Friday, October 19th starting after lunch and concluding with a plenary talk titled "Dare to Repair: from Cancer to Chemistry," by Shiela David who is a biochemist doing DNA repair work at the University of California, Davis. It is a pleasure to have Shiela here for the plenary talk because she and her father (who is a Berea College trustee) have been so generous to Berea over the years with support. The complete listing of seminars and posters is given below.
Students and faculty interested in attending or participating in the 2017 BURS should either contact Jay Baltisberger or Anes Kovacevic of the chemistry program. Alternatively a student may elect to register online via the link on the Chemistry department web server.

Chemical and NMR Analysis of Soil Phosphorus Affected by Waste Overflow

Din Obadele Mandley
Mentor: Paul Smithson
Performed at Berea College
Waste spills from a small confined animal feeding operation (CAFO) on the Berea College farm in east central Kentucky, USA have negatively impacted water quality in a stock watering pond downslope from the swine waste lagoons. In a 2006 study we collected soil samples from 100 georeferenced points in two small watersheds, one that receives lagoon overflow and an adjacent control watershed that receives no swine waste inputs. Available soil phosphorus in the drainage path of the affected watershed was significantly (P < 0.0001) higher than in upland samples from the same watershed. In this study we further characterized the 52 soil samples from the affected watershed. We determined organic and inorganic P in 0.25 M NaOH + 0.05 M EDTA extracts of the soils, and conducted P-31 NMR analysis on the extracts of selected soils from the watershed. Inorganic NaOH-EDTA P was much higher in the treatment drainage compared to adjacent upland samples (mean difference 1560 mg P/kg, P < 0.0001). Organic P was also higher in the drainage path, but much less so (mean difference 900 mg P/kg, P = 0.035). For all samples, estimates of organic P averaged 75% of total NaOH-EDTA P (range 14-100%). P-31 NMR analysis of selected extracts showed most P to be inorganic orthophosphate, with the organic fraction occurring mostly as mono- and diester P. Organic P was about 20-25% of total NaOH-EDTA P as estimated by NMR, suggesting that the commonly used NaOH-extractable organic P value is an overestimate.
