Characterization of the transcriptomes of genetically diverse Listeria monocytogenes exposed to hyperosmotic and low temperature conditions

ABSTRACT: A screening process was used to determine hyperosmotic as well as cold stress tolerance of a diverse set of Listeria monocytogenes strains and was based on the capacity to grow at sub lethal levels of NaCl and 4M-BM-0C. Analysis of gene expression in cells adapted to cold and hyperosmotic stress revealed significant strain specificity in terms of individual gene expression profiles though general patterns of expression within functional gene subsets were largely similar. . Strain ATCC19115 revealed 150 significantly up- and 146 down-regulated genes in cells adapted to both hyperosmotic and cold stress, 82 up- and 56 down-regulated genes were matching in response to both stresses in strain 70-1700, whereas ScottA, a relatively stress-tolerant strain, showed up-regulation of 77 genes whilst
