Introduction

Climate change, fueled by excessive carbon dioxide (CO2) emissions, has spurred global efforts to develop effective carbon capture and storage (CCS) strategies. Among various solutions, microbial strategies have gained attention for their cost-effectiveness, scalability, and potential for sustainability. Microorganisms, including bacteria, algae, and fungi, play a pivotal role in mitigating carbon emissions through biological processes like carbon sequestration, bioenergy production, and soil carbon enhancement [1].

Microbial carbon sequestration involves capturing atmospheric CO2 and converting it into stable organic or inorganic compounds. Cyanobacteria and microalgae are among the most studied microorganisms in this domain. These photosynthetic organisms use sunlight to convert CO2 into biomass, which can be further processed into biofuels or biofertilizers. Certain bacteria, such as Acetobacterium woodii, utilize CO2 as a carbon source through acetogenesis, producing acetic acid that can be industrially exploited [2].

Biochar, a carbon-rich material produced from organic waste, enhances microbial activity in soil, promoting carbon storage. When applied to agricultural lands, biochar acts as a habitat for carbon-fixing microbes, increasing soil fertility and sequestering carbon for decades. This synergy between biochar and microbes reduces the release of greenhouse gases like methane and nitrous oxide, further enhancing environmental sustainability [3].

An emerging field, microbial electrosynthesis, leverages electroactive bacteria to capture CO2 and convert it into valuable organic compounds. These bacteria, such as Geobacter sulfurreducens, use electricity as an energy source to drive CO2 reduction reactions. This technology holds promise for industrial applications, including the production of biofuels, plastics, and pharmaceuticals, while simultaneously addressing carbon emissions [4].

Methanotrophic bacteria play a critical role in mitigating methane, a potent greenhouse gas. These microbes oxidize methane into less harmful compounds like CO2, which can then be captured and stored. On the flip side, methanogenic archaea, which produce methane in anaerobic conditions, are being explored for controlled methane generation in biogas plants, where the gas is captured and utilized as renewable energy [5].

Algae, particularly microalgae, are effective at capturing CO2 due to their high photosynthetic efficiency. These organisms can grow in wastewater or saline environments, making them a sustainable choice for bioenergy production. Algal biomass can be converted into biodiesel, bioethanol, or biohydrogen, offering a dual benefit of renewable energy generation and carbon mitigation [6].

Microbial communities in soil are crucial for carbon cycling. Mycorrhizal fungi, for instance, form symbiotic associations with plant roots, enhancing the storage of organic carbon in soil. Similarly, decomposer bacteria and fungi convert plant residues into humus, a stable form of carbon. Agricultural practices that promote microbial diversity, such as reduced tillage and organic farming, can significantly enhance soil carbon stocks [7].

Microbial bioreactors are engineered systems that optimize the activity of carbon-capturing microbes. These systems are used in industries to capture CO2 from flue gases and convert it into bio-products like ethanol, lactic acid, and biopolymers. Advances in genetic engineering are further enhancing the efficiency of these microbes, making bioreactors a viable option for large-scale carbon capture [8].

Despite their potential, microbial strategies face challenges such as scalability, cost, and energy requirements. Efficient deployment requires integrating these technologies with existing infrastructure. Moreover, maintaining microbial stability and activity in diverse environmental conditions is a critical area of research [9].

The integration of artificial intelligence and synthetic biology is expected to revolutionize microbial carbon capture technologies. AI can optimize microbial ecosystems for maximum carbon fixation, while synthetic biology can create tailored microbes with enhanced capabilities. The combination of these advancements could lead to breakthroughs in environmental sustainability [10].

Conclusion

Microbial strategies for carbon capture offer a promising avenue for addressing climate change and achieving environmental sustainability. By harnessing the natural abilities of microorganisms, humanity can not only reduce atmospheric CO2 levels but also create a circular economy. Continued research and investment in this field are essential to realize its full potential and ensure a sustainable future for the planet.
