Abstract(s)
This book chapter provides an overview of the innovative exogenous green
stimulus methods of electric, magnetic, and ultrasound stimulation and their appli-
cations in boosting bioprocesses. These non-invasive and non-toxic techniques have
been shown to enhance the metabolic activity and stress response of various micro-
bial systems, including bacteria, yeasts, fungi, and microalgae, leading to increased
yields of valuable bioproducts and bioremediation technologies. The chapter begins
with an introduction to the concept of these green stimulus and the rationale behind
its use in bioprocessing. This is followed by a discussion of the different principles
and mechanisms of electric, magnetic, and ultrasound stimulation, including the
physical and biological effects that underpin their efficacy. Additionally, the chapter
covers the application of these techniques in various bioprocesses, including micro-
bial fermentation, biosynthesis of enzymes, and bioconversion of biomass. Examples
are provided to illustrate the benefits of green stimulus in enhancing the production
of specific bioproducts, such as biofuels, pharmaceuticals, and biopolymers. Finally,
we conclude with a critical evaluation of the potential of these techniques in the
bioprocessing industry, highlighting the challenges and limitations that need to be
addressed to fully harness their potential.
