Genetic And Physiological Responses Of Bifidobacterium Animalis Subsp. Lactis To Hydrogen Peroxide Stress, T. S. Oberg, Robert E. Ward, J. L. Steele, Jeff Broadbent

Nutrition, Dietetics, and Food Sciences Faculty Publications

Consumer interest in probiotic bifidobacteria is increasing, but industry efforts to secure high cell viability in foods is determined by these anaerobes’ sensitivity to oxidative stress. To address this limitation, we investigated genetic and physiological responses of two fully sequenced Bifidobacterium animalis subsp. lactis strains, BL-04 and DSM 10140, to hydrogen peroxide (H₂O₂) stress. Although the genome sequences for these strains are highly clonal, prior work showed they differ in both intrinsic and inducible H₂O₂ resistance. Transcriptome analysis of early stationary phase cells exposed to a sub-lethal H₂O₂ concentration detected …

Intellectual Property And Opportunities For Food Security In The Philippines, Jane Payumo, Howard Grimes, Antonio Alfonso, Stanley P. Kowalski, Keith Jones, Karim Maredia, Rodolfo Estigoy

Law Faculty Scholarship

By 2050, the Philippine population is projected to increase by as much as 41 percent, from 99.9 million to nearly 153 million people. Producing enough food for such an expanding population and achieving food security remain a challenge for the Philippine government. This paper argued that intellectual property rights (IPR) can play a key role in achieving the nation’s current goal to be food-secure and provided examples to illustrate that the presence of sound intellectual property (IP) helps foster research, development, and deployment of agricultural innovations. This paper also offered key recommendations about how the IP system can be further …

Food Intake Patterns And Plate Waste Among Community Meal Center Guests Show Room For Improvement, Marjorie Freedman, Catherine Bartoli

Faculty Publications

Food insecure individuals often consume nutritionally inadequate diets. Using a weighted plate waste analysis, we examined whether adult guests of 2 independently operated meal centers were served and consumed Food and Drug Administration–recommended serving sizes (reference amount customarily consumed; RACC) of protein, starch, fruit, vegetables, and bread for the dinner meal. In both centers, guests were served and consumed more than 100% of RACC for protein. Regardless of amount served and independent of whether guests took seconds, consumption of fruit and vegetables was less than RACC. Larger servings of vegetables, but not of protein or starch, resulted in more plate …

The Effect Of Freezing As A Storage Method On Anthocyanin Concentration In Blueberries, Marin E. Plumb

Undergraduate Honors Papers

Blueberries are rich in a water-soluble class of pigments known as anthocyanins which are known antioxidants. Antioxidants help prevent many diseases by stabilizing free radicals, but are prone to losses in food during storage. The goal of this study was to test the effect of freezing as a storage method on anthocyanin concentration and antioxidant activity over time. Blueberries from Canada and Argentina were frozen for up to 5 months and periodically tested for anthocyanin concentration and antioxidant activity. Anthocyanins were extracted using a mixture of methanol, acetic acid, and water, and evaporation under vacuum. They were separated using column …

Antibiotic Resistance In Foodborne Pathogens, Ciara Walsh, Geraldine Duffy

Reports

Wide-spread antibiotic resistance among bacterial pathogens is now a serious public health issue and multi-antibiotic resistance has been reported in many foodborne pathogens including Salmonella and E. coli. A study to determine antibiotic resistance profiles of a range of Salmonella and Verocytotoxigenic E.coli (VTEC) isolated from Irish foods revealed significant levels of antibiotic resistance in the strains. S. typhimurium DT104 were multiantibiotic resistant with 97% resistant to 7 antibiotics. S. Dublin and S. Agona showed lower levels of antibiotic resistance. Antibiotic resistance among VTEC isolates was generally low but two isolates of E. coli O157:H7 from minced beef were shown …

Improved Growth Of Lactobacillus Bulgaricus And Streptococcus Thermophilus As Well As Increased Antioxidant Activity By Biotransforming Litchi Pericarp Polysaccharide With Aspergillus Awamori, Sen Lin, Lingrong Wen, Bao Yang, Guoxiang Jiang, John Shi, Feng Chen, Yueming Jiang

Publications

This study was conducted to increase the bioactivity of litchi pericarp polysaccharides (LPPs) biotransformed by Aspergillus awamori. Compared to the non-A. awamori-fermented LPP, the growth effects of A. awamori-fermented LPP on Lactobacillus bulgaricus and Streptococcus thermophilus were four and two times higher after 3 days of fermentation, respectively. Increased 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity and DNA protection activity of litchi pericarp polysaccharides were also achieved after A. awamori fermentation. Moreover, the relative content of glucose and arabinose in LPP after fermentation decreased from 58.82% to 22.60% and from 18.82% to 10.09%, respectively, with a concomitant increase in the relative contents of …

Crop-Friendly Bacteria Tapped To Battle Fungal Marauders, Patricia Okubara, Jan Suszkiw

Agricultural Research Magazine

Soil-dwelling bacteria that depend on wheat and barley roots for their “room and board” could soon make good on their debt. Researchers are investigating the microbes’ potential to biologically control root-rot fungi that cause crop yield losses of 10-30 percent annually in the U.S. Pacific Northwest and other parts of the world.

The bacteria are members of the genus Pseudomonas and include 11 strains that stymie the growth of Pythium and Rhizoctonia fungi, which are responsible for dampingoff and root-rot diseases of wheat and barley. The pathogens thrive in cool, moist soils and can reach especially high levels in crop …

Characterization Of Antimicrobial-Resistant Staphylococcus Spp. In Food Animals And Retail Meat, Kanika Bhargava

Wayne State University Dissertations

Antimicrobial resistance in Staphylococcus spp. is a worldwide epidemic concern in hospital and community settings. Food animals and retail meat are important reservoirs of these pathogens that can pose potential threat to humans. In this dissertation, we aimed to investigate the molecular epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Coagulase-negative Staphylococci (MRCoNS) in food animals and retail meat to provide insight into the role of agricultural environment in transmitting bacteria of human clinical significance. Furthermore, the potential application of phytochemicals as antimicrobials and antimicrobial adjuvants to control MRSA infections was explored.

CoNS recovered from food animals were characterized by …

Chlorine Dioxide Gas Treatment Of Cantaloupe And Residue Analysis, Simran Kaur

Open Access Theses

Chlorine dioxide is a selective oxidant and powerful antimicrobial agent. Previous work has shown that treatment of cantaloupe with chlorine dioxide gas at 5 mg/L for 10 minutes results in a 4.6 and 4.3 log reduction of E. coli O157:H7 and L. monocytogenes respectively. A significant reduction (p

Current analytical methods for chlorine dioxide and chloroxyanions are only applicable to aqueous samples. Some of these methods have been used to determine surface residues in treated products by analyzing rinse-water. In order to quantify residues in the tissues of a more complex food matrix, while reducing interference from natural organic matter, …

Coca: An Andean Daily Chew, Robert C. Bradley

School of Art & Design Faculty Publications

“Coca: An Andean Daily Chew” distinctly separates the benign tradition of coca chewing in South America, an 8,000 year old practice, from the modern plague of cocaine addiction. The article specifically addresses Western misconceptions about coca. The text goes on to detail many aspects of the process of coca chewing, from the fields of the Andes to the mouths of the chewer. Coca is chewed with quick lime and this process is compared to the preparation of corn tortillas in Mexico. The most celebrated variety of coca, Erythroxylum novogranatense var. truxillense, or Tupa Coca in Quechua, is positioned as the …
