Superfund Research Program
During summer 2010, Sarah experimented and worked with polychlorinated biphenyls (PCBs) under the guidance of Yinan Wei, Ph.D., at the University of Kentucky. She used the Escherichia coli (E. coli) bacteria as a model microbe to examine its tolerance and accumulation of PCB 77. In her experiment, Sarah compared the growth of two different strains of the bacteria under different conditions to determine if and how PCB 77 is uptaken by E. coli. She was only able to draw very general conclusions for her experiment and recommends that the experiment be repeated under slightly altered conditions to further test her hypothesis.
Sarah says that she very much enjoyed her experience in Dr. Wei's lab this summer. Even though she is not interested in pursuing chemistry career, she says that it was still a wonderful experience. The people she worked with were all very friendly and helpful and she greatly enjoyed have them as coworkers and mentors. Sarah found the work she did to be interesting and she says that she gained a lot of knowledge not only the specific subject, but also on general laboratory procedures. Overall, Sarah enjoyed her experience and would recommend this program to others.
