Abstract (English):
The high anthropogenic load on the environment makes it necessary to develop new ways of cleaning the environment. One of the promising methods in remediation processes is the use of living organisms. So, for almost every pollutant, it is possible to select the appropriate strain of microorganisms capable of decomposing certain pollutants. The study used benthic-type microbial fuel cells as promising bioengineering systems that can be applied in various areas of human life - medicine, cleaning and environmental monitoring, in the Internet of Things, etc. In addition, the electrogenic potential created by MFC will facilitate the migration of heavy metals towards the anode, which will simplify the process of their removal from the environment or inclusion in the food chains of anodophilic microbiota. As a result of the study, it was found that the most effective in the design of the MFC are horizontal electrodes. Also, pollutants eventually begin to have a negative impact on the bioelectrogenesis of microbial fuel cells and, accordingly, on the local microbiota.
