Arsenic methylation by marine cyanobacteria Prochlorococcus and Synechococcus

Creator:: Lee, Mikaela
Abstract:: Our experiments aimed to investigate responses of the marine cyanobacteria Prochlorococcus and Synechococcus to toxic arsenic species, such as arsenate, and to understand cellular mechanisms that contribute to arsenic tolerance. We used two strains of Prochlorococcus, a high-light adapted MED4 and low-light adapted MIT9313, both axenic, for cultivation experiments. For...

Biogeochemical Processing of Freshwater Carbon in the Anthropocene

Creator:: Buser, Jessica Z.
Abstract:: Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...

Consequences of Influenza A Virus on Pneumococcal Biofilm Formation and Stability in the Absence of Host Factors

Creator:: Nutter, Laura
Abstract:: Streptococcus pneumoniae and Influenza A Virus both primarily infect the upper respiratory tract, with more severe disease occurring during coinfection than would be caused by either pathogen independently. Until recently, characterization of the interactions between these two pathogens has occurred exclusively in the context of a host or using host-derived...

Exploring the Gut Microbiome of Captive Elephas maximus Experiencing Abnormal Feces

Creator:: Singh, Sehajvir
Abstract:: The gut microbiome of all mammals is composed of a diverse commune of microorganisms including bacteria, fungi, archaea, protozoa and viruses 1. Studies have shown a symbiotic relationship between the gut microbiome and host physiology, with there being implications in health and disease progression 2. In captive animals, there has...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

How Do Parasites Infect Salmon? Comparative Transcriptomics Reveal Myxozoan Adaptations for Parasitism

Creator:: Americus, Benjamin
Abstract:: The phylum Cnidaria contains three main branches: Anthozoa (corals, sea anemones) Medusozoa (jellyfish, hydra), and Endocnidozoa. This latter branch is characterized by parasitism and contains the microscopic fish-parasites Myxozoa. Myxozoa are highly simplified, consisting of only a few cell types, however they have retained the nematocyst stinging cells and complex...

Perceptions of climate change in herbalism and harvesting

Creator:: Noall, Amelia
Abstract:: This study looked at the impacts of climate change on medicinal plants, and how these impacts are viewed and understood in the herbalism community. Two literature reviews were conducted, to look at each of these two ideas: the first was a review of peer-reviewed literature describing research on climate change...

Differences in expression of COVID-19 related inflammatory genes in non-human primates with varying alcohol consumption

Creator:: Co, Amber
Abstract:: Severe cases of COVID-19 have been associated with cytokine storms, leading to widespread inflammation, tissue damage, and organ failure. Pro-inflammatory cytokines have also been shown to play a role in liver diseases, including alcoholic liver disease. To investigate alcohol consumption as a risk factor for SARS-CoV-2 infections and COVID-19 severity,...

The Social Interactions of Pseudomonas aeruginosa

Creator:: Smith, Parker
Abstract:: Pseudomonas aeruginosa is a ubiquitous environmental microbe, opportunistic pathogen, and a highly social organism. P. aeruginosa utilizes a wide array of cooperative behaviors to adapt to the environmental conditions around it. These behaviors include quorum sensing (QS), a form a cell-to-cell signaling that coordinates the expression of secreted products in...

Developing a methodology for expression of full-length dynein intermediate chain in baculovirus

Creator:: Woonnimani, Prajna
Abstract:: Cytoplasmic dynein is a 1.6MDa motor protein complex that functions in transporting cargo along the cytoskeleton. It is made up of different subunits, heavy chain (HC), intermediate chain (IC), and light chains (LC7, LC8, Tctex). The intermediate and light chains interact with accessory proteins NudE and Dynactin (through the large...
