Expression And Isolation Of The Bche Protein From Dinoroseobacter Shibae In Rhodobacter Capsulatus, Abigail Brown, David Bollivar, Faculty Advisor

John Wesley Powell Student Research Conference

Photosynthetic bacteria rely on photosynthesis to get energy. Bacteriochlorophylls harvest the light energy in photosynthesis and are important to these bacteria, but several enzymes used to synthesize this macromolecule are not completely understood. The gene bchE, from the marine bacterium Dinoroseobacter shibae, has been proposed to code for a protein used to help catalyze the formation of the bacteriochlorophyll structure. Isolation of polypeptide encoded by the bchE gene was performed to better understand this enzyme. Using conjugation, ST18 E. coli cells with plasmids containing the bchE gene were mated with a Rhodobacter capsulatus strain lacking functional BchE to …

Phage For Thought: Investigating The Ingestion And Assimilation Of Viruses Into Rotifer (Brachionus Plicatilis) Tissues, Brittany Straznickas, William Jaeckle, Faculty Advisor

John Wesley Powell Student Research Conference

Rotifers are a group of suspension-feeding aquatic invertebrate animals that range from approximately 50–2,000 micrometers in size. The typical food sources for rotifers (i.e., unicellular algae, 2-10 micrometers in diameter) are visible with light microscopy. Bacteriophages (viruses that use bacteria as hosts) are too small (30-110 nanometers in diameter) to be seen using light microscopy, but are present in great abundance (~ 10³⁰ in the world’s oceans). If or how particles as small as bacteriophages are consumed as food is incompletely known; Sorenson ('15) reported that rotifers ingest water containing the fluorescently-labeled (Dichlorotriazinylamino fluorescein, DTAF) bacteriophages. We exposed the …

Functional Analysis Of A Putative Homing Endonuclease, Nikhilesh Thapa, David Bollivar, Faculty Advisor

John Wesley Powell Student Research Conference

Endonucleases are enzymes that cleave phosphodiester bonds within polynucleotide chains such as DNA and RNA. A subgroup, homing endonucleases (HEase) are also able to propagate their encoding genes by transforming host genes to incorporate the homing endonuclease gene (HEG). This process is initiated by the expression of the HEase from the HEG, which then cleaves a homolog. The homolog subsequently undergoes a homologous recombination event as a repair mechanism, and in the process integrates a copy of the HEG. Based on predicted sequence, gene product (gp126) from the mycobacteriophage Gizmo is thought to encode for a HEase. Previous work constructed …

Assessment Of Cranial Neural Crest Proliferation Patterns Between The Redeye Tetra Moenkhausia Sanctaefilomenae And The Zebrafish Danio Rerio, Lesly Ingram, Brian Walter, Faculty Advisor

John Wesley Powell Student Research Conference

Among teleost fishes, there is a substantial amount of diversity regarding craniofacial morphology. This study investigated the cellular processes directing the morphological variations observed in the Meckel’s and ceratohyal cartilages of the zebrafish Danio rerio and the redeye tetra Moenkhausia sanctaefilomenae. Utilizing BrdU incorporation, significant interspecific variations relating to cartilage formation were determined. Specifically, interstitial proliferation was found to be more important for the shaping and subsequent growth of the cartilages in D. rerio than in M. sanctaefilomenae. Correspondingly, the expansion of the pharyngeal arches was more dramatic in M. sanctaefilomenae than in D. rerio. This study demonstrates …

Artistic And Scholarly Sessions: Can A Multicellular Bacterium Prepare Students For Multiple Career Paths?, Loralyn Cozy, Rachel Ende, Class Of 2016, Megan Smeets, Class Of 2017, Christina Khouri, Class Of 2016

Inauguration of Eric R. Jensen

April 2, 2016; 10–10:30 am

How do I support students pursuing their own unique professional goals using my discipline as a backdrop? This, for me, is the defining question for mentorship at a liberal arts institution. Three students and I will consider how collaboration in one discipline, microbiology, can shape a variety of professional trajectories.
