Transcriptome Analysis Of Bifidobacterium Longum Strains That Show A Differential Response To Hydrogen Peroxide Stress, Taylor S. Oberg, Robert E. Ward, James L. Steele, Jeff Broadbent

Nutrition, Dietetics, and Food Sciences Faculty Publications

Consumer and commercial interest in foods containing probiotic bifidobacteria is increasing. However, because bifidobacteria are anaerobic, oxidative stress can diminish cell viability during production and storage of bioactive foods. We previously found Bifidobacterium longum strain NCC2705 had signifi- cantly greater intrinsic and inducible resistance to hydrogen peroxide (H₂O₂) than strain D2957. Here, we explored the basis for these differences by examining the transcriptional responses of both strains to sub-lethal H₂O₂ exposure for 5- or 60-min. Strain NCC2705 had 288 genes that were differentially expressed after the 5-min treatment and 114 differentially expressed genes …

Effect Of Shear Work Input On Steady Shear Rheology And Melt Functionality Of Model Mozzarella Cheeses, Prateek Sharma, Peter A. Munro, Tzvetelin T. Dessev, Peter G. Wiles, Robert J. Buwalda

Nutrition, Dietetics, and Food Sciences Faculty Publications

Model Mozzarella cheeses with varied amounts of shear work input were prepared by working molten cheese mass at 70 °C in a twin screw cooker. Rheology and melt functionality were found to be strongly dependent on total shear work input. A non-linear increase in consistency coefficient (K from power law model) and apparent viscosity and decrease in flow behaviour index (n from power law model) were observed with increasing amounts of accumulated shear work, indicating work thickening behaviour. An exponential work thickening equation is proposed to describe this behaviour. Excessively worked cheese samples exhibited liquid exudation, poor melting and poor …

Department of Biological Sciences Publications

The physical characteristics of bacteriophages establish them as viable candidates for downstream development of pathogen detection assays and biocontrol measures. To utilize phages for such purposes, a detailed knowledge of their host interaction mechanisms is a prerequisite. There is currently a wealth of knowledge available concerning Gram-negative phage-host interaction, but little by comparison for Gram-positive phages and Listeria phages in particular. In this research, the lytic spectrum of two recently isolated Listeria monocytogenes phages (vB_LmoS_188 and vB_LmoS_293) was determined, and the genomic basis for their observed serotype 4b/4e host-specificity was investigated using comparative genomics. The late tail genes of these …

Scaling Up Fruit And Vegetable Production: Is Machinery Sharing A Possibility?, Georgeanne M. Artz, Linda Naeve

Professional Agricultural Workers Journal

Abstract

Interest in local food is growing among consumers and small-scale farmers, as evidenced by the significant increase in the number of farmers’ markets, community-supported agriculture arrangements, and food hubs, in the last ten years. To meet the demand for locally grown fruits and vegetables, many small-scale farmers are considering scaling up their production. However, to remain profitable they need to balance production with increased labor costs and the need for specialized machinery. A study conducted in Iowa worked with five groups of farmers who shared different pieces of machinery. With help from the researchers, they developed sharing agreements and …
