Utilizing Nasa-Funded Biotechnology To Improve Resource Management On Earth And In Space, Tyler Wallentine
Utilizing Nasa-Funded Biotechnology To Improve Resource Management On Earth And In Space, Tyler Wallentine
Research on Capitol Hill
USU senior Tyler is a Peak Summer Research Fellow studying biological engineering. Nitrogen, essential in soil fertilizer for crops, is produced traditionally in a way that uses natural gas and produces CO2. Tyler’s project has been to apply methods developed by NASA for astronauts to conserve and reuse resources to create nitrogen using wastewater and bacteria. Using this method would not only take advantage of waste we already have, but doesn’t produce CO2 and contribute to pollution. Tyler hopes to become a chemical engineer in the space industry and credits his undergraduate research experience. “There’s something about having to obtain …
Toward Lignin Valorization: Development Of Rhodococcus Opacus Pd630 As A Chassis For Triacylglycerol (Tag) Production From Recalcitrant Aromatic Feedstocks, Rhiannon R. Carr
Toward Lignin Valorization: Development Of Rhodococcus Opacus Pd630 As A Chassis For Triacylglycerol (Tag) Production From Recalcitrant Aromatic Feedstocks, Rhiannon R. Carr
McKelvey School of Engineering Theses & Dissertations
The advent of the industrial era was precipitated by the discovery of fossil fuels, and ushered in unprecedented changes for humanity included but not limited to the development of rapid transit and communications, improvements to food distribution and preservation, the mass production of goods, and a radical rearrangement of communities from relatively small enclaves to metropolises. With all the benefits, however, come considerable costs, especially to the global environment. Greenhouse gas emissions, built up over centuries of unregulated combustion, have precipitated a rate of global temperature change unparalleled in the 4.5 billion-year history of this planet. In order to preserve …
Visualizing Bacteriophage Evolution Through Sequence And Structural Phylogeny Of Lysin A And Terminase Proteins: An Analysis Of Protein Structure Across Phage Clusters, Maansi Asthana, Alyssa Easton, Julia Mollenhauer, Sean Renwick, Anita Golpalrathnam
Visualizing Bacteriophage Evolution Through Sequence And Structural Phylogeny Of Lysin A And Terminase Proteins: An Analysis Of Protein Structure Across Phage Clusters, Maansi Asthana, Alyssa Easton, Julia Mollenhauer, Sean Renwick, Anita Golpalrathnam
The Journal of Purdue Undergraduate Research
Understanding how genes evolve and persist is a critical part of viral genomics. Bacteriophages can provide unique insight about viral evolution because of their abundance and largely unexplored history. Traditionally, phylogenetic trees have used DNA sequence comparison to visualize evolutionary paths between organisms. However, DNA sequence similarity does not reflect key alterations to protein structure and therefore how the protein performs its function. Phylogenetic trees based on predicted protein structure could provide an alternative lens through which to view evolutionary paths. From each of the 10 largest clusters included in the Actinobacteriophage Database, three mycobacteriophage genomes were selected. Lysin A …
Cost-Effective Paper-Based Diagnostic Using Split Proteins To Detect Yeast Infections, Zachary R. Berglund, Kevin V. Solomon, Mohit S. Verma, Moiz Rasheed, Zachary Hartley, Kevin Fitzgerald, Kok Zhi Lee, Janice Chan, Julianne Dejoie, Makayla Schacht, Alex Zavala

The common yeast infection, vulvovaginal candidiasis, affects three out of four women throughout their lifetime and can be spread to their child in the form of oral candidiasis (thrush). This disease is caused by the fungal pathogen Candida albicans, which is also a major cause of systemic candidiasis, a rarer but deadly disease with up to a 49% lethality rate. Current widely-used diagnostic methods include cell cultures, pH tests, and antibody detection, to assist effective treatment. Despite availability of various diagnostic methods, there is no inexpensive, rapid, and accurate way to detect C. albicans infection. This project aims to …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Benzene, a toxin and carcinogen found in air polluted by cigarette smoke, car exhaust, and industrial processes, is associated with the development of leukemia and lymphoma. Other than avoiding exposure, there is no current method to deter the effects of benzene. One potential strategy to prevent these effects is to engineer the bacteria of the human lung microbiome to degrade benzene. To evaluate this novel approach, we must verify that the bacteria remain viable within the lung microenvironment. To do so, lungs were harvested from rats and swabbed to determine the contents of the original lung microbiome. Then green fluorescent …
A Multi-Channel 3d-Printed Bioreactor For Evaluation Of Growth And Production In The Microalga Dunaliella Sp, Cristian A. Cox
A Multi-Channel 3d-Printed Bioreactor For Evaluation Of Growth And Production In The Microalga Dunaliella Sp, Cristian A. Cox
Electronic Theses and Dissertations
We explored the capabilities of additive manufacturing using a photo-cured jetted material 3D printer to manufacture a milli-microfluidic device with direct application in microalgae Dunaliella sp growth and intracellular compounds biosynthesis tests. A continuous microbioreactor for microalgae culture was CAD designed and successfully built in 1 hour and 49 minutes using black photopolymer cured by UV and a support material. The microreactor was made up of 2 parts including the bioreactor itself and a microchannel network for culture media fluids and microalgae. Both parts were assembled to form a single unit. Additional optical and auxiliar components were added. An external …
Movement Effects On The Flow Physics And Nutrient Delivery In Engineered Valvular Tissues, Manuel Salinas
Movement Effects On The Flow Physics And Nutrient Delivery In Engineered Valvular Tissues, Manuel Salinas
FIU Electronic Theses and Dissertations
Mechanical conditioning has been shown to promote tissue formation in a wide variety of tissue engineering efforts. However the underlying mechanisms by which external mechanical stimuli regulate cells and tissues are not known. This is particularly relevant in the area of heart valve tissue engineering (HVTE) owing to the intense hemodynamic environments that surround native valves. Some studies suggest that oscillatory shear stress (OSS) caused by steady flow and scaffold flexure play a critical role in engineered tissue formation derived from bone marrow derived stem cells (BMSCs). In addition, scaffold flexure may enhance nutrient (e.g. oxygen, glucose) transport. In this …
Trait Selection And Welfare Of Genetically Engineered Animals In Agriculture, Michael Greger
Trait Selection And Welfare Of Genetically Engineered Animals In Agriculture, Michael Greger
Michael Greger, MD, FACLM
The release of the Final Guidance from the US Food and Drug Administration on the commercialization of genetically engineered animals has sparked renewed discussion over the ethical, consumer, and regulatory implications of transgenesis in animal agriculture. Animal welfare critiques have focused on unexpected phenotypic effects in animals used in transgenic research, rather than on the health and welfare implications of the intended productivity enhancement. Unless breeding goals are redefined to reflect social concerns, the occurrence and magnitude of undesirable side effects may increase and consumer confidence in the nascent technology may be undermined.

Complete Genome Sequence Of Clostridium Clariflavum Dsm 19732, Javier A. Izquierdo, Lynne Goodwin, Karen W. Davenport, Hazuki Teshima
Dartmouth Scholarship
Clostridium clariflavum is a Cluster III Clostridium within the family Clostridiaceae isolated from thermophilic anaerobic sludge (Shiratori et al, 2009). This species is of interest because of its similarity to the model cellulolytic organism Clostridium thermocellum and for the ability of environmental isolates to break down cellulose and hemicellulose. Here we describe features of the 4,897,678 bp long genome and its annotation, consisting of 4,131 protein-coding and 98 RNA genes, for the type strain DSM 19732.
