Development of internally pH-controlled bulk starter media for the propagation of lactic acid bacteria

Creator:: Willrett, Douglas L.
Resource Type:: Dissertation
Full Text:: Galloway West that enabled my last year of research in Fond du Lac to be a most rewarding experience. I

Bacteriophage-host interactions in lactic streptococci : lysogeny, phage inhibition and phage-insensitive mutants

Creator:: Huggins, Alan Roy
Resource Type:: Dissertation
Full Text:: . J. Dairy Res. 43: 141-193. 7. Luria, S. E., J. E. Darnell Jr., D. Baltimore, and A. Campbell. 1978

Characterization of Oregon-derived malo-lactic bacteria : fermentation properties and storage stability

Creator:: Dohman, Thomas Philip
Abstract:: Gram positive cocci isolated from Oregon wines were characterized and their relative malate fermentation abilities compared. They were heterofermentative, catalase negative, and facultatively anaerobic. Glucose, fructose, cellobiose, maltose, ribose, trehalose, salicin and esculin were fermented by all strains. Arabinose was fermented weakly but lactose, raffinose, sucrose, xylose, rhamnose, mannose and...

Aeromonas salmonicida and aeromonas hydrophila (liquefaciens) as pathogens of salmonid fish. A. Selective aeromonas medium. B. Comparative characteristics of virulent and avirulent strains of aeromonas salmonicida. C. Effect of water temperature on aeromonas infections

Creator:: McCoy, Ralph Hines
Abstract:: Studies were directed toward the formulation of a selective Aeromonas medium that would permit the isolation of Aeromonas species in the presence of other common bacterial flora. The final composition of this medium, PBG Agar, in grams per liter, is: Bacto-peptone, 10; Bacto-beef extract, 10; glycogen, 4; NaCl, 5; sodium...

Distribution of Clostridium botulinum type E in fish, shellfish and the marine environment of the Pacific Northwest, and protein patterns of the toxigenic and non-toxigenic stains

Creator:: Craig, James Morrison
Abstract:: Interest in the distribution of Clostridium botulinum type E was heightened by the sudden outbreak of human botulism from smoked whitefish chubs and canned tuna fish in 1963. The question arose as to how widely the organism is distributed among fish and shellfish in the Northwest and what potential hazard...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Growth of lactococci relative to antibiotic and quaternary ammonium compounds

Creator:: Valladao, Marilin
Abstract:: The work presented in this thesis is concerned with the effect of several antibiotics and quaternary ammonium sanitizers upon growth of lactic acid bacteria. Section I reports the purification of beta-lactamase from Lactococcus cremoris PR-108, by ion exchange chromatography, using the chromogenic substrate pyridine-2-azo-p-dimethylaniline (PADAC) as the enzymatic indicator. Section...
Resource Type:: Masters Thesis
Full Text:: expert advise in the analysis of Ster-bac by HPLC, and to Carl Baker for his technical assistance. A

Studies on the inhibition of food-borne pathogens and spoilage bacteria by lactic acid starter cultures

Creator:: Daly, Charles
Abstract:: The ability of Streptococcus diacetilactis to inhibit a variety of food-borne pathogens and spoilage organisms in milk and broth cultures was demonstrated. Test organisms inhibited included Pseudomonas and Alcaligenes species, Eschericia coli, Salmonella, Staphylococcus aureus, Clostridium perfringens and Vibrio parahaemolyticus. In general, approximately 99.0% and 99.9% inhibition was observed in...

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....
