Drake was interested in fecal coliform contamination entering Crooked Lake. Drake collected field samples from November 2019-February 2020. He measured organic matter in the stream, likely fecal coliform load, and bacterial load in the water sampled. He found total contamination did not vary between sampling dates suggesting contamination is from a consistent source (septic systems).
Lily sampled surface water from eight lakes within Steuben County, Indiana. She measured environmental parameters (pH, conductivity, and transparency using Secchi Disk) as well as collected samples for algal biomass (chlorophyll a concentration) and community composition. She found that all lakes sampled showed signs of nutrient enrichment and that each lake had a unique community of phytoplankton.
Current undergraduate organic chemistry II laboratories lack an adequate analogue to graduate and industry work. Thus, a multistep organic synthesis route combining currently used organic reactions will provide a novel laboratory experience and improve the student laboratory experience. The work describes the optimization of the first reaction, the nitration of benzaldehyde, for high purity and efficiency. The optimal conditions found are conducting the reaction at -10 ̊C for 5 minutes and mixing the nitric and sulfuric acids before adding benzaldehyde, which gives a 74% yield.
Brandon Dalley was attempting to construct an expression vector by recombining the DNA of an essential bacterial protein (SPaseI), responsible for the export of virulent and other essential proteins, with a commercially available expression vector using common molecular biology techniques.
Bacteriophage phi 6 is a virus that infects the plant pathogen Pseudomonas syringae. Our study focused on the importance of the nonstructural protein p12 in virus production. We generated truncated versions of the p12 protein through site-directed genomic mutagenesis. These mutated genomes will be combined in host cells to produce mutant recombinant viruses for identification of the region of p12 required for formation of the virus.
Superparamagnetic iron oxide nanoparticles (SPIONs) were synthesized and analyzed under the Scanning Electron Microscopy (SEM) to optimize imaging conditions for analysis.
