Abstract: This dissertation presents an investigation of the application of nuclear magnetic resonance (NMR) spectroscopy as an analytical tool for improved monitoring, diagnostics, and characterization of the wastewaters associated with food waste. NMR uses a non-targeted approach to gather high-resolution molecular-level data relating to the makeup of complex organic mixtures. One and two-dimensional experiments are used to generate an NMR fingerprint of anaerobic bioreactor samples after exposure to a known contaminant. The results determined by NMR are compared to biogas compositions measured using gas chromatography. In all bioreactor samples, key metabolites as well as the contaminant itself are clearly identified, demonstrating changes in the chemical profile in response to stress. For more simple mixtures of food waste, NMR has shown potential to be used as a tool to quickly quantify and predict biodegradability based on macromolecular structure of the organic material in the wastewater.
