This past month, I have focused on finishing data collection for the biofilm/toxin competition assay I conducted last month. After processing the rest of my stored colonies, I calculated initial and final relative frequencies of the biofilm-forming strains in the assay and visualized these data graphically. The resulting graphs illustrate clearly that toxin production affects the fitness of biofilms in competition, which is promising for my current work towards engineering a Trojan Horse strain for biofilm disruption.
I also presented my research twice this month, at the Honors Colloquium and at the Science Symposium. These were great opportunities to practice communicating my research and to answer insightful questions from faculty and other students.
I am now planning to focus on writing for my thesis and on continuing efforts to engineer strains with expression of a cDNA toxin cassette.
