Effect of selected lactic acid bacteria on the growth of food-borne pathogens and spoilage microorganisms in raw milk and milk products

Creator:: Al-Zoreky, Nageb
Abstract:: Several lactic acid bacteria (LAB) of the Lactococcus, Lactobacillus, Leuconostoc and Pediococcus genera were screened for inhibition of food-borne pathogens and spoilage microorganisms in raw milk and dairy products. Listeria monocytogenes was killed by Lactococcus lactis subsp. lactis and Pediococcus pentosaceus due to their production of bacteriocin-type inhibitors. Staphylococcus aureus...

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...

Some microbiological and sensory characteristics of Cheddar cheese manufactured from conventional and ultrafiltered-concentrated milk

Creator:: Betancur, Carmen L.
Abstract:: Cheddar cheese making from ultrafiltered (UF) concentrated milk potentially increases yield, saves raw materials, cuts transportation costs, minimizes waste pollution, and stream-lines production. However, the resulting UF-cheese has been found to differ from conventionally made cheese (CM-cheese) in its casein matrix and ripening process. UF and CM Cheddar cheeses were...

Growth, physiological characteristics and plasmid profiles of Bifidobacterium species

Creator:: Cheng, Ronshan
Abstract:: The fecal flora of healthy bottle or breast-fed infants was examined for the presence of Bifidobacterium. Identification was based on the presence of fructose-6-phosphate phosphoketolase, which is found only in these bacteria. No bifidobacteria were recovered from bottle-fed infants. However, bifidobacteria were readily isolated from 15 day to 3 month...

Roles of yeast and lactic acid bacteria in malolactic fermentation of wines : a chemical and sensory study

Creator:: Avedovech, Richard M.
Abstract:: The purposeful induction of malolactic fermentation (MLF) in wines such as Pinot Noir and Chardonnay is an established commercial wine making practice in Oregon. This induction is not always successful, especially with white wines, such as Chardonnay. A study was initiated to examine the compatibility of yeasts commonly used in...

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...

Characterization of dairy leuconostocs and method to use Leuconostoc mesenteroides ssp. cremoris to improve milk fermentations

Creator:: Levata-Jovanovic, Marina
Abstract:: Dairy leuconostocs are frequently used as aroma-producing bacteria in mesophilic cultures used as starters for milk fermentations. Sixty Leuconostoc strains from different culture collections were studied taxonomically for species identification. Based on morphological, physiological and biochemical tests, twenty of these strains were typed as Leuconostoc mesenteroides ssp. cremoris (Leu. cremoris)....
