I visited Samaria Villalobos’ poster. It was titled Characterization of cultivable bacteria in activated sludgefrom the Adjuntas’ Wastewater Treatment Plant in Puerto Rico. It dealt with describing the cultivable bacteria members in activadted sludge from the plant and comparin its composition with members of a distant treatment unit. I asked her about the method she used for the actual characterization of the bacteria and the type of processing done in the plant. She demonstrated having considerable knowledge on her project.
Then I went to Militza Lozada’s poster. Her project was titled Generation of GFP Variants using Error Prone PCR and Characterization in Escherichia coli. She argued GFP’s (Green Flourescent Protein) usefulness as a marker to study when proteins are made and where they go. She mentioned how she amplified GFP using normal and error prone PCR conditions. This kind of PCR is done by adding extra Mg+ ions to the amplification reaction in order to promote errors during the amplification of the DNA by the polymerase. The purpose of this (and of the project itself) was to develop new GFP proteins.
Finally, I did not have enough time to visit L.M. Cruz’s poster. It was titled Development of a Biosensor using Hbl of Lucina Pectinata with Purification Methods and Characterization by Electroanalytical Technique. I learned that the purpose of the study was to observe the electrochemical properties of several biomaterials. It reports the purification methods for recombinant Hbl and Hbl/Sol-gel (TMOS) electrode, arranged by intermolecular interactions of the recombinant hemoglobin I from Lucina pectinata and TMOS in a carbon paste electrode.
I enjoyed showing my poster during the Poster Session and also I enjoyed reading and hearing my friends talk about their posters. However, I think it could have been a much more productive use of our time if professors from every university evaluated them and gave us feedback.
