Plants and bacteria are often used in combination with pulsed electric fields (PEFs) to improve processes or quality parameters. Although microbial inactivation is a common goal from the usage of this technology, the induction of a stress response, stimulation, or increased mass transfer can enhance subsequent cellular operations. These effects can be observed after sublethal PEF exposures, which require much lower energy inputs compared with lethal exposures. This work reviews the current state of literature regarding the beneficial effects of sublethal PEF exposures on plants and bacteria, and how they can be used to improve current processes.
