Annual climate conferences draw public attention to the urgent need to ecologize CO2-neutral fuel systems and recognize that global temperature increases must be limited to less than 2 °C to avoid dangerous climate change. Based on the projections of the International Panel on Climate Change, it is now widely accepted that in order to stay within this temperature range, CO2 emissions need to be reduced by 80% by 2050.
The article presents a study of the influence of Lemna minor population density on the bioelectric potential and current of model electro-biosystems in the laboratory сonditions using 500 and 1000 Ω resistors and in the open circuit. The positive effect of increasing the density of duckweed plants populations from 60 to 120 fronds/ml on the growth of bioelectric parameters of model electro-biosystems under load conditions and without resistors was revealed. Increasing the amount of duckweed biomass is a factor of enhancing the efficiency of electro-biosystems based on L.
