Decoding The Mystery Of Antibiotic Persistence, Tahmina Hossain
Electronic Theses and Dissertations
This work combines microbiology, molecular biology, Next-Generation Sequencing and system biology approaches to explore the mechanism of antibiotic persistence: a multi-drug tolerant, non-dividing, and metabolically altered state present in a subpopulation of cells due to phenotypic diversity rather than genetic variation (i.e. mutations). Persister can survive lethal antibiotic state and resuscitate after the treatment period is over. They are considered as the major contributing factor behind recurring infections. They also have a high mutation rate, which increases the chances of bacteria gaining antibiotic resistance. The formation of this phenotypic variant (persister) threatens the therapeutic effectiveness of antibiotics and understanding how …

Phosphorus Use And Management Based On Fertilizer Placement, Rate Of Application, And Soil Biota In No-Till Situations, Brennan Alexander Bingham Lewis
Electronic Theses and Dissertations
Phosphorus (P) pollution has become a concern among multiple scientific organizations as it leads to eutrophication, an algal bloom that depletes lacustrine and marine ecosystems of native species. Multiple strategies can be implemented to reduce phosphorus loss from agriculture fields, which is often implicated as a cause of eutrophication. Soil phosphorus chemistry results in phosphate fertilizers absorbing to clay minerals over time. Soil phosphorus is lost from agricultural fields primarily through wind and water erosion. No-till practices prevent soil erosion, which reduces the phosphorus from loading into waterways. Fertilizer placement affects phosphorus loss. Surface application of phosphorus fertilizers increases the …
