Journal ArticleDOI
Behavior of acid-adapted and unadapted Escherichia coli O157:H7 when exposed to reduced pH achieved with various organic acids.
TL;DR: It is shown that organic acids differ in their inhibitory or lethal activity against acid- Adapted and unadapted E. coli O157:H7 cells, and acid-adapted cells are more tolerant than un Adapted cells when subsequently exposed to reduced pH caused by these acids.
Journal ArticleDOI
Tolerance of acid-adapted and non-adapted Escherichia coli O157:H7 cells to reduced pH as affected by type of acidulant
TL;DR: There was essentially no difference in growth characteristics of the two types of cells in TSB acidified at the same pH with a given acid, and on plates not showing visible colonies, acid‐ Adapted cells retained higher viability than unadapted cells when plated on acidified TSA.
Journal ArticleDOI
Influence of temperature and pH on survival of Escherichia coli O157:H7 in dry foods and growth in reconstituted infant rice cereal
TL;DR: Survival appeared to be enhanced in foods with highest pH, and acid- Adapted cells retained higher viability than unadapted cells in only two of the nine test foods, particularly at refrigeration temperature.
Journal ArticleDOI
Survival of Escherichia coli O157:H7 in dried beef powder as affected by water activity, sodium chloride content and temperature.
TL;DR: In this paper, a study was carried out to determine the rate of inactivation of Escherichia coli O157:H7 in beef powder as affected by aw(0·34±0·06± 0·01), sodium chloride content (0·5, 3·0 and 20%) and temperature (5 and 25° C) over an 8-week storage time.

TL;DR: In this paper , the changes of rice blast-resistance (R) genes over time and their ultimate impact on pathogen AVR genes were analyzed by PCR using gene-specific markers of the nine R genes and six primer pairs targeting the coding sequence or promoter of AVR, respectively.
