Escherichia Coli
New Escherichia coli research reported from Ohio State University
January 13th, 2009
According to recent research from the United States, "Investigating mechanisms of lethality enhancement when Escherichia coli O157:H7, and selected E. coli mutants, were exposed to tert-butylhydroquinone (TBHQ) during ultra-high pressure (UHP) treatment. Escherichia coli O157:H7 EDL-933, and 14 E. coli K12 strains with mutations in selected genes, were treated with dimethyl sulfoxide solution of TBHQ (15-30 ppm), and processed with UHP (400 MPa, 23 +/- 2 degrees C for 5 min)." "Treatment of wild-type E. coli strains with UHP alone inactivated 2.4-3.7 log CFU ml(-1), whereas presence of TBHQ increased UHP lethality by 1.1-6.2 log CFU ml(-1); TBHQ without pressure was...
