Phytoremediation has the potential to significantly reduce water contamination caused by excessive harmful chemicals. The degradative properties of fungi are used in fungal phytoremediation to eliminate or neutralise the hazardous pollutants present in water. The goal of the current study was to endophytize water lettuce with the two entomopathogenic fungus Metarhizium anisopilae and Trichoderma harazium. The plant is inoculated with the fungus using the root-dipping procedure. There were two main treatments and a control all with five replications. The analysis of plant and wastewater were analyzed initially like frequency of fungus remained in plant weight, root length and for …

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 …

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 …

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 …

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 …

Investigating Drivers Of Algal Bloom Succession In Lake Erie, Brittany Zepernick
Doctoral Dissertations
Harmful Algal Blooms (HABs) are algae undergoing prolific, unregulated growth. A well-documented HAB taxa is the cyanobacterium Microcystis spp., which induces anthropogenic, ecological, and economic consequences due to the production of toxins and biomass which results in lake hypoxia. Microcystis spp. blooms are globally distributed in freshwater systems, with climate change and the aquatic continuum serving to further exacerbate bloom distribution, duration, and frequency. Thus, there is a need to elucidate the factors driving the ecological success of Microcystis spp., and the ecological “failures” of their competitors, such as diatoms. In Lake Erie, a seasonal pattern of algal bloom succession …

Fecal contamination has continued to plague local communities around the United States and the world, especially in highly populated areas like Southern Florida. Newer techniques are beginning to be used to track microbes properly as they are found in waterways. Some more recent techniques in Microbial Source Tracking (MST) use IDEXX kits to detect fecal indicator bacteria (FIB). Two IDEXX kits Colilert-18® which detects total coliforms and Escherichia coli in water or fecal coliforms in wastewater, and Enterolert®, which targets enterococci, were used in the waterways of the Himmarshee Canal and South Fork of the New River …

The Use Of Aloe-Based Silver Nanoparticles As A Possible Treatment For Contaminated Water, Lozetta Davis
Scholar Week 2016 - present
Water contamination is a world-wide issue that causes the death of millions yearly. This comes from regularly tainted water with water borne pathogens, which is typically seen in undeveloped areas. As antibiotics are used more, more resistance is being seen, and thus newer methods of microbial contamination need to be developed. Silver nanoparticles have shown success in microbial contamination on petri dishes, but not in a water system. It was hypothesized that if silver nanoparticles were added to bacteria contaminated water they would be able to reduce the amount of bacteria present. Silver nanoparticles that are synthesized from plants such …

Molecular Biodiversity Of Foraminifera, Rabindra Thakur
Masters Theses
Foraminifera are a diverse clade of mostly shell-building single-celled organisms. Estimation of foraminiferal diversity is critical for understanding past and present climatic conditions, as they are highly sensitive to environmental perturbations. Biodiversity estimates of foraminifera began with the counting of test (i.e., shell) microfossils composed of calcium carbonate, as they are well preserved in sediment samples. However, this view has changed with molecular biodiversity estimates, which suggest that early-diverging single-chamber (i.e., "monothalamid") species that lack preservation ability are more diverse than anticipated. Although biodiversity estimates of foraminifera at the molecular level have changed our perceptions, they possess various challenges, especially …

The Application Of Microbial Source Tracking To Aid In Site Prioritization For Remediation In Lower Michigan, John J. Hart
Masters Theses
Non-point source fecal pollution is a threat to both the environment and public health. Climate change, aging infrastructure, and intensified agricultural practices are predicted to accentuate this issue. In Michigan, due to the high instance of aging infrastructure and intensified agriculture, non-point source fecal pollution has caused many waterbodies to exceed the state standards posing a risk to recreational activities and source water. Due to this threat, there is an increased effort to identify and remediate these sources. My study focused on improving the identification of non-point source fecal pollution through a combination of culture-based and molecular fecal indicator bacteria …

Honors College
Wild Atlantic salmon in the Gulf of Maine (GOM) is a Distinct Population Segment (DPS) that has been listed since 2000 as endangered by the U.S. Fish and Wildlife Service (USFWS) and the National Oceanic and Atmospheric Administration (NOAA). The current challenge is year-over-year decreases in the number of mature salmon returning to the Penobscot River for reproduction. Early detection of pathogen presence could allow for the identification of infection and the application of corrective measures. Environmental DNA (eDNA) is simply DNA that is collected from environmental samples (e.g., water, air, and soils), which consists of whole microorganisms and genetic …

Compared to microbiomes on other skin sites, the bacterial microbiome of the human hand has been found to have greater variability across time. To increase understanding regarding the longitudinal transfer of the hand microbiome to objects in the built environment, and vice versa, 22 participants provided skin microbiome samples from their dominant hands, as well as from frequently and infrequently touched objects in their office environments. Additional longitudinal samples from home environments were obtained from a subset of 11 participants. We observed stability of the microbiomes of both the hand and built environments within the office and home settings; however, …

Graduate Industrial Research Symposium
Fish is one of the most important nutrient sources of the human diet, and its low-cost aquaculture production is advantageous. During processing, large quantities of organic and inorganic nutrients are produced. Discharging fish farming wastewater to the environment without proper treatment can support harmful algal growth. Therefore, aquaculture effluent must be treated prior to discharge to the receiving waters. In this study, six different cyanobacteria and algae species, including Chlorococcumminutum, Porphyridiumcruentum, Chlorella vulgaris, Microcystis aeruginosa, Chlamydomonas reinhardtii, and Fischerellamuscicola were studiedto treatfish aquaculture wastewater, using mix-culture bacteria as the inoccolum. All samples were incubated for 21 days. Parameters such as …
