The microbial stability of refrigerated intermediate moisture foods

Creator:: Li, Ken-yuon
Abstract:: The lag phase, the specific growth rate, the minimum a [subscript w] required for growth and the temperature characteristic of Fsendomonas fluorescens, Brochothrix thermosphacta, Salmonella typhlmurium, Streptococcus faecalis and, Staphylococcus aureus have been studied in liquid model media under controlled temperature and a [subscript w] conditions. The results show that...

Edible food coatings to control potassium sorbate diffusion from surface into food bulk : characterization of the diffusion process in polysaccharide based films

Creator:: Vojdani, Fakhrieh
Abstract:: Edible coatings controlling preservative migration from surface to food bulk could inhibit surface microbial growth which is often the main cause of spoilage for many food products. In this project we focused our attention upon methylcellulose, hydroxypropyl methylcellulose, and chitosan as the structural component for such edible films. These films...

Effect of molecular conformation on the surface properties of polyelectrolyte solutions : xanthan gum model studies

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...

The use of relaxation to solve harvest scheduling problems with flow, wildlife habitat, and adjacency constraints

Creator:: Torres-Rojo, Juan Manuel
Abstract:: Lagrangean relaxation is presented as a solution technique to solve flow constrained area-based harvest scheduling problems. The best set of multipliers in the Lagrangean approach is obtained through the subgradient method. Guidelines to set some parameters to compute the step size in the subgradient algorithm are provided. An additional procedure...

Investigations into the physiology of nitrogen fixation : Part I. Nickel metabolism of plants and bacteria : Part II. Peroxide scavenging in soybean root nodules

Creator:: Dalton, David Andrews
Abstract:: PART I. The concentration of nickel in some soils may be insufficient to meet the requirements of enzymes such as urease in soybeans and hydrogenase in Rhizobium. Nickel availability in soils was examined by measuring microbial urease activity in soils which were treated with glucose and urea. Supplemental nickel was...

Preformulation studies for oral dosage forms of lactobacilli

Creator:: Liou, Grace Yow-Hwa
Abstract:: Lactobacilli have been used in the dairy and pharmaceutical industries because of their nutritious and/or therapeutic effects. Lactobacillus acidophilus and Lactobacillus bulqaricus were isolated from a commercially available product and studied for their growth and colony characteristics as described in Chapter I and Chapter II. Survival of these lactobacilli in...

Formulation studies of lactic acid-producing bacteria for oral administration

Creator:: Liou, Yow-Hwa Grace
Abstract:: Effects of lactobacilli in enteric coated capsules were studied in piglets (Chapter I). Lactobacillus acidophilus and Lactobacillus bulgaricus isolated from a commercial product were formulated in capsules, enteric coated, and then given to both Escherichia coli-challenged and unchallenged baby pigs. Decreased incidence and severity of diarrhea, and decreased weight deceleration...

Plasma membrane composition and luteinizing hormone receptors of ovine corpora lutea during early pregnancy

Creator:: Zelinski, Mary Beth
Abstract:: The lipid composition of plasma membranes of corpora lutea was examined to determine whether changes in this organelle occur during regression and early pregnancy in the ewe. Forty ewes were assigned to be necropsied on days 13 or 15 of the estrous cycle (D13-NP and D15-NP) or pregnancy (D13-P and...
