“…Other species including Glyceria maxima, Spartina anglica, Arundinella anomala, Lemna minuta, and Arundo donax have been studied in PMFCs and showed current production associated with plant rhizodeposits (Helder et al, 2010(Helder et al, , 2012aHubenova and Mitov, 2012;Strik et al, 2008;Timmers et al, 2010Timmers et al, , 2012Wetser et al, 2015). Power production has been improved through the optimization of plant selection, reactor configuration, or nutrient media (Chen et al, 2012;Helder et al, 2012a,b;Moqsud et al, 2014;Wetser et al, 2015).…”

“…With return to the optimal level of precipitation, more than 2 mm per day, the plants were restored, bioelectric parameters rose, approaching the initial values. As shown in the paper (Hubenova & Mitov, 2012), the current depends on the physiological stage of the plant and decreases when plants die. Frequent weather abnormalities: prolonged droughts and periods of heat that have become frequent for Ukraine, a moderate climate country, due to global climate change hinder the prospect of the sustainable use of wetlands with C. palustris as a source of eco-electricity without resorting to special measures.…”

“…Under these conditions, there is not a large excess of synthesized organic substances and, accordingly, the secretion of organic substances into the soil is weak, which leads to a significant reduction in the activity of electric-generating microorganisms and a decrease in their production of current strength. As shown by Hubenova & Mitov (2012), the current strength depends on the level of illumination of the samples.…”

“…Currently, eco-electric microbial-plant biotechnology is faced with the problem of low power (Helder et al, 2013;Nitisoravut et al, 2017;Wetser et al, 2017). The methods for maximizing the collection of microbial-plant eco-electricity are the selection of new plants (Helder et al, 2010;Hubenova & Mitov, 2012), the use of new electrode systems (Picot et al, 2011;Chen et al, 2012;Rusyn & Valko, 2019), synthetic nutrient media (Helder et al, 2011;Yadav et al, 2012;Liu et al, 2013), natural media (Rusyn, 2014;Moqsud et al, 2015;Wetser et al, 2017). The objective of this work is to makea contribution to the optimization of electro-biotechnology.…”

Soil plant-microbial biosystems are a promising sustainable technology, resulting in electricity as final product. Soil microbes convert organic products of plant photosynthesis and transfer electrons through an electron transport chain onto electrodes located in soil. This article presents a study of prospects for the generation of bioelectricity by a soil plant-microbial electro-biotechnological system with Caltha palustris L. (Ranunculaceae), a marshy winter-hardy plant that develops early in the spring and is widespread in the moderate climatic zone, in clay-peat medium and with introduction of Lumbricus terrestris L. (Lumbricidae). The experiment was carried out in the wetlands of the Ukrainian Polissya and the Carpathian mountains in situ, and on the balconies and terraces of buildings to assess the possibilities of using green energy sources located directly in buildings. The electrodes were placed stationary in the soil to measure the values of bioelectric potential and current strength. We monitored the bioelectricity indices in open circle and under load using external resistors, and calculated the current density and power density, normalized to the soil surface covered by plants and electrodes. The revealed high maximal values of the bioelectric potential, 1454.1 mV, and current, 11.2 mA, and high average bioelectricity values in optimal natural conditions in wetlands in situ make C. palustris a promising component of soil plant-microbial bio-electrotechnology. We analyzed the influence of temperature and precipitation on the functioning of the soil plant-microbial biosystem. The use of thickets of C. palustris in wetlands in situ, as a stable source of plant-microbial eco-electricity in the summer, is complicated by the fact that the plant sensitively reacts to long periods of high temperature and periods of drought, which is accompanied by decrease in the level of bioelectric parameters. The cultivation of the marsh plant C. palustris as a component of electro-biosystems is possible on terraces and balconies of buildings. The cultivation of C. palustris in clay-peat soil with electrode system for production of eco-electricity on shaded balconies and terraces of buildings requires optimal irrigation, lighting, and introduction of L. terrestris into the substrate, which increase the bioelectricity values of this biotechnology.

Production of bioelectricity from substrates with growing plants and developing microorganisms is the newest technology of alternative energetics that has great perspectives. The efforts of scientists around the world are aimed at improving biotechnology: the development of effective electrode systems for the collection of plant-microbial bioelectricity, the search for new plants, suitable for technology, testing of new substrates for the development of plants. In this paper, we presented tests of new model electro-biosystems (EBS) consisting of graphite-zinc-steelical systems of electrodes with stainless steel elements placed in plastic containers with soil substrate and planted sedges Carex hirta. The experiment was conducted during the year on the roofs of a university building in the climatic conditions of the Western Ukrainian region to assess the functioning of the electro-biosystems in outdoor conditions. We analyzed the different types of electrode placement in containers: with the horizontal alocation of the electrodes under the root system, with the vertical placement cathodes and anodes in a container and with the increased contact area of the cathodes with the substrate and reinforced connecting of cathodes with each other. During the experiment, we monitored the bioelectric potential of the samples which were in an open circle and under load of an external resistor. To analyze short-term voltage and current, polarization measurements were performed by changing the external resistance from 10 Ω to 5 kΩ, and the current strength, current density and power density were calculated. The conducted experiments showed C. hirta can be successfully cultivated on green roofs in open soil in the climatic conditions of the Western Ukrainian region. The studied electro-biosystems operate round-the-year as the plants are frost-resistant. Metereological conditions, especially the temperature and precipitation intensity, affect the electro-performance of the electro-biosystems on the roofs. The maximum average weekly current of 21.36 mA was recorded in May at optimum temperatures and a favourable humidity level, with an average temperature of 11.4 °C and rainfall of 5.39 mm/day. The electrical performance of electro-biosystems decreases during the winter and dry periods without an organized irrigation system. During the winter period, electrode systems are damaged by adverse factors. The configuration of the electrode system EBS3 is less susceptible to breakdowns due to the destructive action of water during freezing in the winter and more effective in collecting bioelectricity. The research represented in the paper is one more step towards improving bioelectricity technology on green roofs.
