Microbiological control of food spoilage and pathogenic microorganisms in refrigerated foods

Creator:: Al-Zoreky, Nageb
Abstract:: Microgard, a commercially-available pasteurized fermented milk, was found inhibitory to gram negative bacteria such as Pseudomonas putida, some well-known foodborne pathogens (e.g. Salmonella, Yersinia and Aeromonas) and some fungi as revealed by an agar incorporation assay method. Gram positive bacteria, however, were not inhibited. Rather, some bacteria in this group...

Characterization of 16S Ribosomal RNA Probe-Isolated Lactococci from nature for use in Cheddar cheese manufacture

Creator:: Daniels, Brent E.
Abstract:: Strains of Lactococcus lactis ssp. lactis and Lactococcus lactis ssp. cremoris with potential use in the food industry which had been previously isolated from nature using 16S rRNA probes were characterized for unique identifying traits and for attributes important for potential use in cheese manufacture. Strains of Lc. cremoris which...

Studies to improve lactic acid bacterial starter cultures

Creator:: Khosravi, Lewa
Abstract:: Three commercial sausage starter cultures were grown in an internal-pH-controlled medium (PHASE 4) and in a soluble phosphate-buffered medium. The cultures were tested by comparing viable counts before and after freezing at -40 C or freeze-drying and subsequent storage for 3 months in the frozen or dried state. Strains varied...

Effect of quaternary ammonium compounds on bacteria : comparison of sensitive and resistant strains of the same species

Creator:: Albin, Inga Anna Schroder
Abstract:: To determine whether some bacteria are more susceptible than others to quaternary ammonium compounds, the following bacteria were grown on agar slants containing various concentrations of alkyl dimethyl ethyl benzyl ammonium chloride (ADEBAC), and alkyl dimethyl benzyl ammonium chloride (ADBAC): Aerobacter aerogenes 12658, Alcaligenes metalcaligenes, Brevibacterium linens, Chromobacterium lividum, Escherichia...

Bacteriophages for Leuconostoc oenos : a survey of Oregon wineries

Creator:: Eschelbach, Matthew Michael
Abstract:: A study of malolactic bacteria of the Leuconostoc genus, especially L. oenos, and their bacteriophages was conducted. A search for the presence of infectious bacteriophages in grapes, musts, and juices employed in malo-lactic fermentation (MLF) was conducted; no evidence, either physical or biological, was found for the existence of these...

Mechanisms of lactose metabolism by strains of Streptococcus lactis

Creator:: Walter, Leslie Alva
Abstract:: Rapid acid production by lactic streptococci used in the manufacture of fermented dairy products is essential to the economy of the industry and to the public health of consumers. There remains to developed, however, an adequate laboratory procedure to detect and distinguish between slow and fast strains of these bacteria....
