Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, Mallory J. Suhr May 2015

Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, Mallory J. Suhr

Dissertations, Theses, & Student Research in Food Science and Technology

Gastrointestinal microbiome studies have failed to include fungi in total community analyses. As a result, their diversity and function in the gut is poorly understood. Recent work has begun to uncover the role intestinal fungi play in diet, immune system development, interactions with other microorganisms in the gut, and pathogenesis of diseases. Advances in sequencing technologies allow for the ability to profile the fungal gut microbiome (“mycobiome”) in healthy and diseased states. This thesis explores the mycobiome in 1) healthy humans with a vegetarian diet and 2) pediatric small bowel transplant recipients that develop fungal bloodstream infections.

The gut mycobiome ...


Characterization Of Extraction Methods To Recover Phenolic Rich Extracts From Pinto Beans That Exert High Antioxidative Activities Using Response Surface Approach, Mohammed Aldawsari Apr 2014

Characterization Of Extraction Methods To Recover Phenolic Rich Extracts From Pinto Beans That Exert High Antioxidative Activities Using Response Surface Approach, Mohammed Aldawsari

The pinto bean has been linked to the prevention of multiple diseases due in large part to the presence of phenolic antioxidants, which are higher in beans than in many fruits and vegetables. These components deliver health properties beyond basic nutritional characteristics by scavenging free oxygen radicals. However, these benefits are most likely due to the ability of these chemically diverse phenols to impart greater protective properties as additives or synergists acting in combination. However, optimal parameters to isolate these compounds (in terms of ratios and types) from a given natural source are not known. Without this knowledge, understanding the ...
