“…The choice of plant for electrobiotechnology is an important factor that determines how efficiently it will work. When using the same electrode system, but with different plants, the performance of PMFC differed significantly [26,27,36], the difference in bioelectricity generation reached up to 10 times, as described in experiments [25]. The plant can be considered an engine of bioelectricity generation, since photosynthesis and excretion of photosynthetants and secondary metabolites, as well as the root system itself, which can be hydrolyzed to nutritious compounds, represent a significant source of power for electroactive microorganisms.…”
