Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...

Creator:: Chotyakul, Nattaporn
Abstract:: Quantitative procedures were developed to determine the effect of variability in the model parameters required for the estimation of microbial shelflife and thermal processing time. Monte Carlo simulations combined with these predictive models were implemented in Microsoft Excel™. In the first study, predictive models were used for shelf-life predictions based...

Creator:: Young, San Land
Abstract:: A commercially important polyelectrolyte, xanthan, was chosen for a systematic analysis of the relationship between molecular conformation and surface properties. In the first study the effects of ionic strength, xanthan concentration and temperature on the xanthan molecular conformation were investigated by potentiometric titration. The effects of the same factors and...

Creator:: Escobedo-Avellaneda, Zamantha, Velazquez, Gonzalo, Torres, J. Antonio, and Welti-Chanes, Jorge
Abstract:: Shelf-life is the time period during which products retain market-acceptable quality while meeting legal and safety requirements. Deterministic models yield single value estimations of shelf-life typically based on average or worst-case values for input parameters. In deterministic calculations, considering the input parameter variability can be challenging. In this study, a...

Creator:: Chescheir, Stuart C.
Abstract:: The yeast Brettanomyces bruxellensis is the most important wines spoilage yeast encountered during winemaking as it can survive in wine for long periods, requires minimal nutrients for growth, and can be difficult to control. Brettanomyces produces two major spoilage products, the volatile phenols 4-ethylphenol (Band-Aid, medicinal smell) and 4-ethylguaiacol (smoke,...

Abstract:: Pediococcus cerevisiae, Lactobacillus casei, Lactobacillus plantarum, Leuconostoc mesenteroides, Lactococcus diacetylactis Bifidobacterium bifidum, Leuconostoc oenos, and mixed cultures of Propionibacterium shermanii and P. cerevisiae were used to ferment cucumber juice brine (CJB) at 22-26°C for 1.5 months. Sugar utilization ranged from 14.6 to 86.1%. pH of the fermented CJB ranged from...

Creator:: Johnson, Jared D.
Abstract:: Given the many significant roles that bacteria play in modern food manufacturing, it is crucial that we have a fundamental understanding of how bacterial communities assemble and behave in the food manufacturing environment. The focus of this dissertation was to investigate both the spatial and temporal distributions of microbial communities...
