Voltage generated by different plant species in microbial fuel cells

Voltage values without external load associated with plant microbial fuel cells using different plant species: aloe (Aloe vera), corn (Zea mays), black beans (Phaseolus vulgaris), tomato (Solanum lycopersicum) and moss (Dicranidae). For the collection of the reported voltages, the voltage associated with the vegetable microbial fuel cells was measured using different species of plants (corn, moss, tomato, beans, aloe and a blank cell). These measurements were made manually, each using a DT9208A multimeter, whose appreciation is ±0.5%, every 6 hours for 7 continuous days to validate the behavior of the voltage during the day and at night. On the other hand, the plants were also subjected to environmental stress due to dehydration by depriving them of irrigation with water for 3 days in order to be able to appreciate the voltage values under conditions of mild drought or little irrigation. Then, the values were recorded in excel where a graph was made and parameters such as standard deviation and average voltage were estimated
