Current advances in Microbial Carbon Capture Cells (MCC) – A unique bioelectrochemical system for sustainable future

Abstract

Carbon sequestration is considered a potential solution to reduce CO₂ emissions and slow down the rate of climate change. Scientists are constantly searching for cost-effective ways to capture carbon on a large scale. One of the sustainable methods to capture carbon is biological sequestration, where CO₂ is absorbed through photosynthesis to create valuable biomass. Microbial Carbon Capture Cell (MCC) is a type of bioelectrochemical system that can use CO₂ and organic substrate, such as wastewater, to produce biomass and generate bioelectricity. Although it is a promising technology, it still needs further development to become a competitive option for a sustainable future. This review article will delve into the principle of MCC, its advantages over traditional methods, the types of substrates and microbes commonly employed, recent developments, and factors that affect its performance. Moreover, in this analysis, the current body of research on MCC has been evaluated and potential areas for future study have also been proposed.
