objective and methodology
Objective and methodology

Objective

  • Doing a literature study on bacteria stress response to high pressure processing (HPP).
  • The bacteria response - change of gene expressions and mechanisms in the cell when stressed.

Methodology

  • Using experimental data done with HPP at 400 Mpa and 600 Mpa with Listeria contaminated food
  • Find vital HPP affected mechanisms  Genes activating these mechanisms  Determination of most significant genes  Comparing genes with regulation from other environmental stresses  Proposing the most pressure specific genes

results and conclusion
Results and conclusion

HPP induced changes

Many genes expressed as a response to HPP

Expression change higher at 400MPa than 600 Mpa less developed response systems for higher pressures.
