“…Research on growth stimulation by an electric field has a long history; positive effects have been established in fungi, soy, microalgae, and other cells (Bertholon, 1783; Lemström, 1904; Bachman and Reichmanis, 1973; Takaki et al, 1984; Costanzo, 2008; Frey et al, 2011; Gusbeth et al, 2013; Mattar et al, 2015). However, controlled and reproducible growth stimulation was currently not possible.…”

The bio-based industry is urged to find solutions to meet the demands of a growing world population. In this context, increased resource efficiency is a major goal. Pulsed electric field (PEF) processing is a promising technological solution. Conventional PEF and the emerging area of nanosecond PEF (nsPEF) have been shown to induce various biological effects, with nsPEF inducing pronounced intracellular effects, which could provide solutions for currently faced challenges. Based on the flexibility and continuous operation of PEF and nsPEF processing, the technology can be integrated into many existing cultivation systems; its modularity provides an approach for inducing specific effects. Depending on the treatment conditions, selective inactivation, continuous extraction without impeding cell viability, as well as the stimulation of cell growth and/or cellular compound stimulation are potential applications in the bio-based industry. However, continuous treatment currently involves heterogeneous energy inputs. Increasing the homogeneity of PEF and nsPEF processing by considering the flow and electric field heterogeneity may allow for more targeted effects on biological cells, further increasing the potential of the technology for bio-based applications. We provide an overview of existing and potential applications of PEF and nsPEF and suggest that theoretical and practical analyses of flow and electric field heterogeneity may provide a basis for obtaining more targeted effects on biological cells and for further increasing the bio-based applications of the technology, which thereby could become a key technology for circular economy approaches in the future.

SUMMARY This paper presents an experimental study of control of the germination of Arabidopsis seed with a barrier discharge produced by polarity‐reversed voltage pulses. 100 ns‐width polarity‐reversed pulses were applied to the seeds between plane electrodes covered by glass barriers. The electrode configuration allowed barrier discharge propagation along the seed surface at a relatively low voltage. After the discharge treatment, the seeds were incubated for 2 or 3 days to measure the germination rate. The relationships between the cumulative input energy density into the plasma and the germination rate were investigated. The germination rate was significantly reduced at 20 J/cm3. However, it increased at cumulative energy densities up to 50 J/cm3 and then decreased again on further energy input. These results suggest a superposition of two effects, stimulation and inhibition, of the discharge treatment on the germination of Arabidopsis seed. The results of Evans Blue dyeing of the discharge‐exposed seeds indicate that necrosis of the seed coat is caused by the discharge treatment.
