Screening For Potential Swine-Origin Probiotics With Antimicrobial Activities, Christina Lim
Screening For Potential Swine-Origin Probiotics With Antimicrobial Activities, Christina Lim
Animal Science Undergraduate Honors Theses
The prevalence of antibiotic resistant bacteria is a leading issue worldwide. Recently, there was a new law banning the use of antibiotics within the swine industry. For decades swine producers have mixed subtherapeutic amounts of antibiotics in swine feed to prevent potential infections and to increase growth rate. However, due to the constant exposure of antibiotics to these ever-evolving pathogens, the population of antibiotic resistant bacteria has increased exponentially. Currently, the swine industry is scrambling to find a suitable alternative to antibiotics that possesses antimicrobial activity and potentially promotes growth. The objective of this study was to investigate the ability …
Effects Of Ambient And Laser Light On Water Evaporation From The Surface Of Polyurethane Swabs Doped With Surfactant, Collin Campbell
Effects Of Ambient And Laser Light On Water Evaporation From The Surface Of Polyurethane Swabs Doped With Surfactant, Collin Campbell
Chemical Engineering Undergraduate Honors Theses
Polyurethane swabs are a common instrument for environmental sampling in the food, medical, and forensic fields due to their high recovery of organisms like viruses, spores, and bacteria. For sampling microbes in food and medical facilities, storage of the collected samples occurs under the absence of light to promote growth for more accurate testing. In the forensic fields, microbial growth results in sample contamination so the inhibition of this growth requires the drying of the swabs. This work studies the evaporation rates of water from polyurethane swabs under zero watt incident light, 30 W fluorescent bulb, 50 mW 532 nm …
Redesigning Gfp Reporter System For Utilization In Clostridium Difficile, Laura E. Fitzgerald
Redesigning Gfp Reporter System For Utilization In Clostridium Difficile, Laura E. Fitzgerald
Biological Sciences Undergraduate Honors Theses
Clostridium difficile (C. difficile) is a gram-positive bacterium that comprises part of the healthy human gut microbiome. When it gains sufficient access to peptides, C. difficile flourishes and releases tissue-damaging toxins, which cause inflammation of the colon that can develop into a Clostridium difficile Infection (CDI).10 The Ivey Laboratory believes that the best tactic in preventing CDIs is stopping peptide ingestion, which theoretically could be accomplished by manipulating the oligopeptide permease (App) system.7 In order to verify that altering the App system would successfully impede peptide uptake, first the expression of the app Promoter Region ( …
Role Of Lactic Acid Bacteria As A Bio-Sanitizer To Prevent Attachment Of Listeria Monocytogenes On Deli Slicer Contact Surfaces, And The Influence Of Listeria Innocua On The Attachment Of L. Monocytogenes On Selected Materials Located In The Food-Processing Environment, Jean Baptiste Ndahetuye
Graduate Theses and Dissertations
Listeria monocytogenes an important foodborne pathogen that continues to be a serious problem for the food industry. This pathogen contaminates food primarily during post-harvest in the food-processing environment. Its ecology in the food-processing environment is not well understood but previous research has demonstrated the ability of L. monocytogenes to survive on food contact surfaces after cleaning and disinfection. The current study explored the attachment of three lactic acid bacteria (LAB) strains, Lactobacillus animalis , Lb. amylovorus and Pediococcus acidilactici , their combination in a cocktail, and their influence to prevent the attachment of L. monocytogenes at room temperature by examining …

Linoleic acid isomerase (LAI) is the enzyme that converts linoleic acid to conjugated linoleic acids (CLAs) which appear to be capable of lowering cancer risk and enhancing immunity. There is an interest in developing commercial processes for the production of single isomers of CLA by biotransformation of LA using microbial cells and enzymes. However, the evaluation of these strains suggest that growth and LA isomerase production levels by these anaerobes are insufficient to support economic commercial production of single CLA isomers. A better alternative is to clone the isomerase gene and to generate new production strains using recombinant technology. Bifidobacterium …
