Inhibition Of Adhesion Of Streptococcus Mutans To Hydroxylapatite By Commercial Dairy Powders And Individual Milk Proteins, Rachel Halpin, Maeve O'Connor, Dolores O'Riordan, Michael O'Sullivan, Damien Brady

Articles

The aim of this study was to investigate the inhibitory effect of various dairy powders and milk constituents on the adhesion of a clinical isolate of Streptococcus mutans to hydroxylapatite (HA), an analogue of tooth enamel. Adhesion of a microorganism to a cell surface such as epithelial cells or tooth enamel is considered to be the first step in pathogenesis. Inhibiting this process may have therapeutic effects in vivo. The adherence assays were performed by incubating S. mutans with HA in the presence of each test material for 45 min, followed by centrifugal separation of the HA. Unbound bacteria were …

Design And Synthesis Of Carbohydrate Based Derivatives As Antimicrobial Compounds, Aoife Smith

Doctoral

Investigations into the design of analogues of GlcNAc-Ins, the substrate for the enzyme GlcNAc-Ins deacetylase (mshB), a therapeutic target on the pathway to mycothiol biosynthesis in Mycobacterium tuberculosis are described. Initial studies directed towards the design of a substrate analogue were based on the 3-D structure and a proposed mechanism of action of mshB (deduced by Dr. Andrew McCarthy, EMBL). The compounds were designed with the aim to produce an analogue which could better mimic the natural substrate for mshB (GlcNAc-Ins) for crystallisation and mechanistic studies to further improve the knowledge of this enzyme. A series of fatty acid ester …

Guide To Floor Malting Of Sorghum And Millets, John R.N. Taylor

INTSORMIL Scientific Publications

Malt (dried, sprouted cereal grain) is the major ingredient in most beers and in certain hot and cold beverages. It is also a useful ingredient in some cereal food products such as bread and infant porridges. In terms of nutrients, malt contains mainly complex carbohydrates (starch and dietary fiber), but also protein of reasonable quality and availability, B vitamins and minerals. Malt is a source of hydrolytic enzymes, especially amylases. In brewing, the malt amylases produce the sugars which the yeast ferments to alcohol and carbon dioxide The amylases also increase the sweetness and improve the texture of food products …

Assessing The Effect Of Product Variability On The Management Of The Quality Of Mushrooms (Agaricus Bisporus), Catherine Barry-Ryan, Jesus Maria Frias, Leixuri Aguirre, Helen Grogan

Articles

To study the shelf-life of mushrooms, over 25 batches were subjected to three storage temperatures (T) (5, 15 and 25 ◦ C) and three storage relative humidity (RH) levels (70, 80 and 90%). The effect of T and the RH on the kinetics of quality attributes of the batches was studied by measuring water activity, turgor, colour (L, a* and b* in the Hunter Scale) and weight loss of three different tissues (cap, gills and stipe) of the mushroom. Linear mixed effect models, comprising polynomial models to describe quality kinetics and allowing for batch-to-batch and inside-batch nested variabilitystructure, were built. …

Effect Of Iron Source On Color And Appearance Of Micronutrient-Fortified Corn Flour Tortillas, A. T. Richins, K. E. Burton, Heather F. Pahulu, Laura K. Jefferies, Michael L. Dunn

Faculty Publications

Iron deficiency anemia is a widespread occurrence. Consequently, iron is commonly added in cereal fortification programs. However, many iron sources cause undesirable sensory changes, especially color changes, in the food being fortified. This study evaluated the effect of different iron sources on CIE L*a*b* color values and sensory color perception in fortified corn tortillas. Corn masa flour was fortified with micronutrient premix containing vitamins, zinc, and one of eight iron compounds. Iron sources included ferrous fumarate (F), ferrous sulfate (S), ferric orthophosphate (OP), ferrous lactate (L), ferrous gluconate (G), ferric pyrophosphate (PP), sodium iron (III)-EDTA, and A-131 electrolytic iron (E), …

Secondary Metabolism Inducing Treatments During In Vitro Development Of Turmeric (Curcuma Longa L.) Rhizomes, Matthew M. Cousins, Jeffrey W. Adelberg, Feng Chen, James Rieck

Publications

Turmeric (Curcuma longa L.) plants that were grown in vitro for 17 or 22 weeks as a fed-batch culture in 2.5 L vessels yielded 39 to 43 g and 62 to 70 g of fresh rhizomes per vessel, respectively (95 % confidence interval). The MS liquid medium was maintained at 6 % sucrose through media addition twice during the experiment. Various methods were employed in attempts to increase secondary metabolism. Antioxidant and total phenolics assays were employed to characterize phytochemical activity. A first experiment exposed four clones to phenylalanine and/or methyl jasmonate (MeJa) from week 12 to 17 in …

In Vitro And In Vivo Techniques For Screening New Natural Product-Based Fungicides For Control Of Strawberry Anthracnose, Maritza Abril

Dissertations

Seven plant pathogenic fungi (Botrytis cinerea, Colletotrichum acutatum, C. fragariae, C. gloeosporioides, Fusarium oxysporum, Phomopsis obscurans, and P. viticola) valuable in screening fungicide efficacy were tested. Optimal and reproducible conditions for germination of these selected fungi were established by incorporating Roswell Park Memorial Institute 1640 (RPMI) as a medium of known composition and washing conidia to remove innate germination inhibitors. This step reduced average fungal germination times between 3.5 h and 21.2 h. The natural product-based fungicide, sampangine, seven sampangine analogs (4-bromo-sampangine, 4-methoxysampangine, benzo[4,5]sampangine, liriodenine Mel AMC-XIII-103, onychine, cryptolepine, and liriodenine CDH-II-37), plus seven conventional fungicides (benomyl, captan, cyprodinil, fenbuconazole, …

Food Science and Nutrition

The socio-demographic, behavioral and anthropometric correlates of C-reactive protein levels were examined in a representative young adult Brazilian population. The 1982 Pelotas Birth Cohort Study (Brazil) recruited over 99% of births in the city of Pelotas that year (N = 5914). Individuals belonging to the cohort have been prospectively followed up. In 2004-2005, 77.4% of the cohort was traced, members were interviewed and 3827 individuals donated blood. Analyses of the outcome were based on a conceptual model that differentiated confounders from potential mediators. The following independent variables were studied in relation to levels of C-reactive protein in sex-stratified analyses: skin …

The Anti-Microbial Efficacy Of Plant Essential Oil Combinations And Interactions With Food Ingredients, Jorge Gutierrez, Catherine Barry-Ryan, Paula Bourke

Articles

The objective of this study was to evaluate the efficacy of plant essential oils (EOs) in combination and to investigate the effect of food ingredients on their efficacy. The EOs assessed in combination included basil, lemon balm, marjoram, oregano, rosemary, sage and thyme. Combinations of EOs were initially screened against Bacillus cereus, Escherichia coli, Listeria monocytogenes and Pseudomonas aeruginosa using the spot-on-agar test. The influence of varying concentrations of EO combinations on efficacy was also monitored using E. coli. These preliminary studies showed promising results for oregano in combination with basil, thyme or marjoram. The checkerboard method was then used …

Recent Applications Of Chemical Imaging To Pharmaceutical Process Monitoring And Quality Control, A. A. Gowen, Colm O'Donnell, Patrick J. Cullen, S. Bell

Articles

Chemical Imaging (CI) is an emerging platform technology that integrates conventional imaging and spectroscopy to attain both spatial and spectral information from an object. Vibrational spectroscopic methods, such as Near Infrared (NIR) and Raman spectroscopy, combined with imaging are particularly useful for analysis of biological/pharmaceutical forms. The rapid, non-destructive and non-invasive features of CI mark its potential suitability as a process analytical tool for the pharmaceutical industry, for both process monitoring and quality control in the many stages of drug production. This paper provides an overview of CI principles, instrumentation and analysis. Recent applications of Raman and NIR-CI to pharmaceutical …
