“…With electrical grounding, a relatively higher PFU was expected to be transferred from the suspension (C in Figure 1 ) to the submerged leaf (B in Figure 1 ). Previous research 18 has shown that electrical grounding of plants induces higher germination and growth rates, and the grounding of plant pots provides a suitable “electrochemical environment” resembling cultivation on natural soil. Without electrical grounding of the plant (for instance, an electrically isolated indoor plant), the accumulation of charged molecules on the plant surface may negatively affect the growth of the plant, due to the hazardous range of electricity.…”

“…Reports have shown that during cultivation, experimental plant pots with electrical earth connections enhanced plant growth and activity compared to pots without earthing (i.e., conventional indoor plant pots that are electrically isolated from the earth – an infinite electricity sink). 18 , 19 These reports suggested that electrical grounding of indoor plant pots provides geo-electrochemically friendly growth conditions for plants similar to those provided by plants that are connected (or grounded electrically) to the earth’s surface. Other reports have shown that plant growth and metabolism are closely related to the electromagnetic environmental conditions.…”

Control of hazardous indoor particles using plants has attracted interest due to the increasing worldwide air pollution and spread of pandemic-causing viruses. However, the interaction between human pathogenic viruses (HPVs) and live plants has not been examined largely due to issues in detecting tiny amounts of infectious viruses in a carrier (such as an aerosol) and the lack of suitable examination methods. In this study, as a novel evaluation method, the effect of submerged leaves of live plants on HPVs in water was examined, using the H1N1 influenza virus as a model. Selected plant foliage of a live plant was immersed in a small bag containing HPV water suspension. In an initial screening test, the activities of 20 different plant species on the virus suspension were evaluated using a rapid virus detection kit. Ten plant species had the capability to decrease virus concentrations in the water suspension within 72 h. Among the experimental plant species, Epipremnum aureum showed the highest virus decreasing characteristics when examined using both the kit and quantitative real time polymerase chain reaction. The capacity of immersed leaf of live E. aureum to decrease viral content was enhanced when the plant-containing pot was electrically grounded to the earth (approximately 70% decrease in virus concentration). The foliage sample analysis showed that virus adsorption to the plant foliage surface could be the major reason for the decrease in the suspension. These results suggest that the proposed method can be applied to select plants to further investigate plant–HPV interactions.

A plant health monitoring method based on a plant microbial fuel cell (PMFC) technique was investigated. The reducing action of plant exudates on electrochemically active bacteria (EAB) in the rhizosphere was used as the basis of the method. Ardisia pusilla was used as an experimental plant. The results indicated that the open circuit potential (OCP) development from the PMFC is closely related to plant health and affected by the cultivation environment. Distinctive OCP developments were observed using the PMFC with live, dead (heat shocked), or no plant. Cultivation conditions such as watering, fertilizing, temperature variation, and lighting affected OCP development from the PMFC. Plant root viability analysis indicated that OCP development from the PMFC is closely related to plant health. These results suggest that this method based on the PMFC technique is a facile, cost‐effective, and rapid tool for monitoring plant health.

Objectives : In this study, the absorption of heavy metals in the soil from smoking areas using indoor plants and electrical grounding was investigated to increase the utility of indoor plants for soil decontamination.Methods : Soil from plant pots in a smoking area was collected for the experimental plant pot preparations. Some of the prepared pots were connected to electrical ground via an electrode. Kidney beans (Phaseolus vulgaris) were seeded, and their growth were observed. After 30 days of the cultivation, TOC (Total Organic Carbon), and metagenomics profiles in the soil was analyzed. To estimate the behavior of the heavy metals in soil and plants, Cadmium concentrations in the samples were analyzed using ICP-MS (Inductively Coupled Plasma-Mass Spectrometry).Results and Discussion : The connection of the electrical ground to the plant pot induced the rapid growth of plant (48.2 ± 2.3% increase in stem growth), compare to the plant in the pot without the electrical ground. TOC analysis showed that the soil from the grounded pots showed the highest value, compared to the control soil (3.08 ± 1.22%), and the soil from the pot without ground connection (2.3 ± 0.1%). The ICP-MS analysis indicated that the plant body in the grounded pot had the highest cadmium concentration at 0.33 ± 0.018 μg/kg. Using the metagenomic analysis, biomineralization related bacterial species (Nocardioides sp., Streptomyces sp., Sphingomonas sp. etc.) were identified from the grounded soil sample. These results suggested that the indoor plant cultivation with the electrical ground connection as an electrical fertilizer enhances the cadmium absorption by plant, exudate secretion from the plant root, and bacterial flora change in the rhizosphere.Conclusion Cadmium in the soil from the smoking area was absorbed by indoor plant with the electrical ground. Therefore, the application of the electrical ground connection (earth) to the electrically insulated outdoor plant pots might enhance the plant growth rate and physiological activity. This application could be a novel soil decontamination method using plants.
