Effectiveness Of Windrow Composting Methodology In Killing A Thermo-Tolerant Species Of Salmonella During Mortality Composting, Spencer Gabriel Myers
Effectiveness Of Windrow Composting Methodology In Killing A Thermo-Tolerant Species Of Salmonella During Mortality Composting, Spencer Gabriel Myers
Master's Theses
In a large agricultural operation, such as the one at Cal Poly San Luis Obispo, disposal of deceased animals is an immense issue. The cost of transporting and rendering every dead animal is inhibitory to the general function of the agricultural operations and their thin budget. Therefore, we propose that composting mortalities could be an economical alternative. Composting is a recognized method for taking animal waste products along with carbon waste and turning it into a pathogen-free, nutrient-rich topsoil. Carcass composting is in fact performed in other countries and states to varying degrees of success. However, the California EPA limits …

Background
RNA polymerase holoenzyme (Eσ) mediates transcription in eubacteria, and is composed of five constant subunits (α2ββ’ω) and a variable sigma (σ) subunit that is responsible for promoter recognition and initiation of transcription. An alternative sigma factor in Salmonella Typhimurium, σ54 (also called RpoN), is mechanistically different than classical σ70-type sigmas, requiring a different promoter consensus sequence, an activator, and ATP hydrolysis. The Rtc RNA repair operon lies within the regulon of RpoN in S. Typhimurium, but has no known physiological function. Previous work characterized similar systems in archaea and humans, which were determined to …
