Detection And Control Of Environmentally Transmissible Viruses, Anand R. Soorneedi
Doctoral Dissertations
Viruses, owing to their ubiquitous nature and ability to infect almost every other species, have long been a subject of interest for scientists. Some of the virus species can be very deadly to humans and animals alike and can impose a huge economic and health burden across the world. The recent CoVID-19 pandemic underscores the importance of timely detection for developing effective intervention strategies. Unfortunately, some of the virus species that cause significant health and economic impacts do not have robust and reliable detection methods due to several reasons. In some cases, despite having gold standard methods for detection of …

Climate Change, Giant Viruses And Their Putative Hosts, Sarah K. Tucker
Masters Theses
Viruses hold our attention for the horrific impact they have on human health and welfare. However, viruses are a critical part of our ecosystem and facilitate the cycling of carbon and other important nutrients. The cycle of virus infection, followed by host resistance and the subsequent evolution of new strains enables adaptation to changing hosts and the environment. Giant viruses, some with particle sizes large enough to be visible in light microscopes and their bewildering array of accessory genes, have captivated scientists and the general public since their discovery two decades ago. Giant viruses are part of the Nucleocytoviricota (NCV) …

Embry-Riddle Aeronautical University
Plastic Recycling Using Waxworms: Biotechnology Solutions, Lance Wood
Sustainability Conference
As small particles that do not degrade, microplastics harm the environment. Plastics are physically broken down rather than chemically during the traditional recycling process. An insect naturally found in honeybee hives known as the waxworm can break down the most common plastic: polyethylene. A literature review was conducted on a new method to recycle plastics involving the waxworm Galleria mellonella. Literary review studies suggest that recycling using waxworms is more efficient and faster than traditional methods due to oxidation by enzymes. After conducting a literature review, a bioinformatics study was carried out using published DNA and protein sequences. Two promising …

Tracing Evolution Of Gene Transfer Agents Using Comparative Genomics, Roman Kogay
Dartmouth College Ph.D Dissertations
The accumulating evidence suggest that viruses and their components can be domesticated by their hosts, equipping them with convenient molecular toolkits for various functions. One of such domesticated system is Gene Transfer Agents (GTAs) that are produced by some bacteria and archaea. GTAs morphologically resemble small phage-like particles and contain random fragments of their host genome. They are produced only by a small fraction of the microbial population and are released through a lysis of the host cell. Bioinformatic analyses suggest that GTAs are especially abundant in the taxonomic class of Alphaproteobacteria, where they are vertically inherited and evolve …

Roles Of Soil Pores In Determining Water Retention And Microbial Dynamics, Huihui Sun
Doctoral Dissertations
Soil pore provides an essential habitat for microbial communities to participate in various biogeochemical processes. The complex pore spaces, which are defined by the arrangement of particles of varying sizes, govern the distribution of water for microbial dispersal and movement and microbial interaction with one another, such as bacterial cell-to-cell and bacterium-virus interactions. This research focused on exploring how soil pores influence soil water retention and bacterial interactions and quantify the spatial distribution of bacteria and viruses in fine-scale of soil pores. Using a mathematical model, this study simulated a soil water retention curve based on the relationship between soil …

Biological nitrogen fixation, the conversion of N2 gas into a bioavailable form, is vital to sustaining marine primary production. Studies have shifted beyond traditionally studied tropical diazotrophs. Candidatus Atelocyanobacterium thalassa (or UCYN-A) has emerged as a focal point due to its streamlined metabolism, intimate partnership with a haptophyte host, and broad distribution. Here, we explore the environmental parameters that govern UCYN-A’s presence at the San Pedro Ocean Time-series (SPOT), its host specificity, and statistically significant interactions with non-host eukaryotes from 2008-2018. 16S and 18S rRNA gene sequences were amplified by “universal primers” from monthly samples and resolved into Amplicon …

The Influence Of Sampling Frequency On Bee Species Richness, Courtney Caccamo
Biology Student Scholarship
As one of Earth’s most valuable pollinators, bees provide important pollination services to wild plant species and crops alike (Winfree 2010). But, in recent years, bee populations appear to be declining due to a variety of anthropogenic drivers (Potts et al. 2010). Quantifying the extent of bee population decline is difficult because there is currently a lack of a standardized protocol for how best to survey bee populations (Tepedino & Portman 2021). One of the commonly used survey methods is pan trapping, which involves leaving out yellow, white, and blue bowls filled with soapy water to passively sample the species …

Considerations For The Use Of Mycorrhizal Fungi Inoculants In Coal Mine Reclamation And Reforestation In Appalachia: A Guide Of Best Practices And Management Recommendations, Cole Hansen Reistrup
Master's Projects and Capstones
Nearly all terrestrial plants form symbiotic relationships with mycorrhizal fungi. These beneficial soil microbes support plant health by increasing plants’ access to nutrients and water, protecting them from pathogens, improving soil properties, and more. A challenge to restoring forests on coal mined land in Appalachia is that mine soils are often degraded in a number of ways, including lacking mycorrhizal fungi, which makes mine soils difficult for trees to grow upon. Substantial improvements to coal mine reforestation success have been made since the development of the Forestry Reclamation Approach in 2005 that provides guidelines for how to create a suitable …

Mechanistic Examination Of Protist-Mediated Plant Growth Through The Comparative Development Of Medicago Truncatula, Shane Connolly
University Scholar Projects
Protists are known to increase plant growth through two main mechanisms: the microbial loop and the alteration of the root microbiome. The microbial loop is a nutrient recycling method in which protists provide inorganic nitrogen ions to the plant. Alteration of root microbiome leads to the removal of plant pathogens and shifting communities towards plant growth-promoting bacteria (PGPB). This study aimed to elicit which mechanism could produce the largest boost in shoot weight for Medicago truncatula. A series of microcosm experiments were explored in which M. truncatula was grown with variable microbiome structures to allow for mechanism differentiation. The …

The Effect Of Algal Wastewater Treatment Systems On Microbial Communities, Alexis Leach
University Honors Program Senior Projects
In collaboration with the Metropolitan Water Reclamation District of Greater Chicago and Gross-Wen Technologies, I examined the microbial communities in experimental tertiary wastewater treatment systems employing algal phytoremediation. Three algal phytoremediation systems were examined: two vertical conveyor belt systems, known as the 10-foot belt system and the series 4 system, and a third system lacking a converter belt in which planktonic algae grew in a control pond. I used EcoPlates to measure carbon substrate utilization by microorganisms in each system. EcoPlates contain thirty-one different carbon substrates, with a dye that indicates microbial use of each substrate. I conducted a Principal …
