What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

Creator:: Soffer, Nitzan
Abstract:: Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...

Virus resistance in transgenic plants expressing translatable and untranslatable forms of the tobacco etch virus coat protein gene sequence

Creator:: Lindbo, John A.
Resource Type:: Dissertation

The use of omics for disease evaluation in the brains of marine mammals

Creator:: Rosales, Stephanie
Abstract:: Marine mammals are top predators that are essential for the health and function of our oceans. These top predators are often affected by various factors that can be detrimental to their populations. Therefore, there is a need to evaluate undetermined causes of deaths and to better understand known diseases in...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Survival of fecal coliform bacteria in sludge-amended soils

Creator:: Hartel, Peter G.
Abstract:: A study was conducted to determine the effects or temperature, solar radiation, rainfall, and saturated flow on fecal coliform numbers in sewage sludge-amended soils. To determine this, four 4.6 X 13.7 m field plots were each amended in summer and in winter with 800 liters of anaerobically-digested sewage sludge, and...

Full Text:: , the consensus for soil (Morrison and Martin, 1977) is similar to that for water (McFeters et al

Studies on purification and characterization of an autolytic enzyme from cell walls of Bacillus subtilis

Creator:: Brown, Willie Claiborne
Abstract:: The purpose of this investigation was to purify and characterize the autolytic enzyme from cell walls of Bacillus subtilis 168. The crude enzyme was obtained by autolysis of purified cell walls in buffer at 37° C. Two purification methods were developed. The first involved fractional precipitation with ammonium sulfate. The...

Studies on host range, fine structure, and nucleic acids of lactic streptococcus bacteriophages

Creator:: Nyiendo, Joanne Annette
Abstract:: The most frequent cause of insufficient acid production during fermentation of dairy products is bacteriophage infection of lactic starter cultures. Previously, efforts to minimize this problem have dealt primarily with the host range relationships of the viruses and susceptibility patterns of the lactic streptococci. This study was undertaken to characterize...

Single-Cell Genomics of Uncultivated Marine Bacteria

Creator:: Landry, Zachary
Abstract:: Historically, the difficulty of obtaining pure cultures of abundant marine microbial plankton has an obstacle to reconstructing the underlying mechanisms of biogeochemistry in the ocean. While a number of dominant marine species from the ocean surface have been cultured, the dominant microbial plankton of the dark ocean proved far more...

Quorum sensing gene regulation in Pseudomonas aeruginosa

Creator:: Gupta, Rashmi
Abstract:: Pseudomonas aeruginosa is an opportunistic human pathogen that infects immunocompromised individuals such as those suffering from burns or the genetic disorder cystic fibrosis. This organism utilizes a cell-cell communication mechanism known as quorum sensing (QS) to coordinate virulence gene expression and biofilm formation. It has three interconnected QS systems, namely...
