Bacteriophages Infecting Gram-Negative Bacteria in a Commercial Cucumber Fermentation

FRONTIERS IN MICROBIOLOGY, 11.

By: Z. Lu *, I. Perez-Diaz  n, J. Hayes n & F. Breidt n

author keywords: bacteriophage; Gram-negative bacteria; Enterobacteriaceae; Enterobacter; cucumber fermentation
TL;DR: The abundance and variety of phages infecting Gram-negative bacteria, particularly Enterobacteriaceae, in the commercial cucumber fermentation is revealed, suggesting that phages may play an important role in the elimination of Gram- negative bacteria, thereby facilitating the dominance of LAB and minimizing bloater defect.

2007 journal article

Determination of 5-log reduction times for food pathogens in acidified cucumbers during storage at 10 and 25 degrees C

JOURNAL OF FOOD PROTECTION, 70(11), 2638–2641.

By: F. Breidt n, J. Hayes n & R. McFeeters n

MeSH headings : Adaptation, Physiological; Beverages / microbiology; Colony Count, Microbial; Consumer Product Safety; Cucumis sativus / microbiology; Escherichia coli O157 / growth & development; Escherichia coli O157 / physiology; Food Handling / methods; Food Microbiology; Food Preservation / methods; Humans; Hydrogen-Ion Concentration; Listeria monocytogenes / growth & development; Listeria monocytogenes / physiology; Salmonella enterica / growth & development; Salmonella enterica / physiology; Temperature; Time Factors
TL;DR: E. coli O157:H7 is found to be the most acid-resistant microorganism for the conditions tested, with a predicted time to achieve a 5-log reduction in cell numbers at 10 degrees C of 5.7 days. (via Semantic Scholar)

2005 journal article

Determination of 5-log pathogen reduction times for heat-processed, acidified vegetable brines

JOURNAL OF FOOD PROTECTION, 68(2), 305–310.

By: F. Breidt*, J. Hayes*, J. Osborne n & R. McFeeters*

MeSH headings : Adaptation, Physiological; Consumer Product Safety; Cucumis sativus / microbiology; Escherichia coli O157 / growth & development; Escherichia coli O157 / physiology; Food Handling / methods; Food Microbiology; Food-Processing Industry / standards; Hot Temperature; Humans; Hydrogen-Ion Concentration; Listeria monocytogenes / growth & development; Listeria monocytogenes / physiology; Models, Biological; Salmonella / growth & development; Salmonella / physiology; Time Factors
TL;DR: Estimated pasteurization times and temperatures needed to assure a 5-log reduction in the numbers of Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella strains in acidified cucumber pickle brines show that current industry pasteurized practices offer a significant margin of safety.

2004 journal article

Independent effects of acetic acid and pH on survival of Escherichia coli in simulated acidified pickle products

JOURNAL OF FOOD PROTECTION, 67(1), 12–18.

By: F. Breidt*, J. Hayes n & R. McFeeters n

MeSH headings : Acetic Acid / pharmacology; Colony Count, Microbial; Dose-Response Relationship, Drug; Escherichia coli O157 / drug effects; Escherichia coli O157 / growth & development; Fermentation; Food Microbiology; Gluconates / pharmacology; Hydrogen-Ion Concentration
TL;DR: Glutamic acid, an amino acid that is known to enhance acid resistance in E. coli and is a component of pickle brines, protected the E. Escherichia coli strains from the specific effects of acetic acid. (via Semantic Scholar)
