‘Chonkus’ Algae Discovered Off Italian Coast Could Offer Solutions for Climate Change Mitigation

A groundbreaking strain of cyanobacteria, nicknamed “Chonkus,” has been discovered in the hydrothermal waters surrounding Italy’s Vulcano Island, stirring excitement due to its potential for carbon capture. The strain, formally known as UTEX 3222, was found during a marine study focused on collecting water samples from the volcanic vents in the region. The large cyanobacteria exhibit unique properties that may make them valuable in efforts to mitigate climate change by capturing carbon dioxide (CO₂) from the environment.

The volcanic hydrothermal environment around Vulcano Island is rich in carbon dioxide, which provides an ideal setting for Chonkus to thrive. Research has shown that this strain of cyanobacteria produces carbon-dense granules within its cells, a characteristic that accelerates its sinking rate in the ocean. As the algae absorb CO₂ from the surrounding water, they become more efficient at sequestering carbon, eventually sinking to the ocean depths where the captured carbon is stored for long periods, potentially reducing atmospheric CO₂ levels over time.

Beyond its natural role in marine ecosystems, Chonkus presents intriguing possibilities for industrial applications, particularly in carbon capture technologies. This cyanobacteria’s ability to store carbon internally could offer significant advantages for industries looking to reduce their carbon footprints. Studies suggest that Chonkus may be able to improve carbon capture efficiency by up to 30 percent compared to other methods, potentially lowering energy costs for industrial processes. This could be a game-changer in efforts to combat climate change through more sustainable and cost-effective means.

The discovery of Chonkus has drawn attention from leading scientists, including Professor George Church, a prominent researcher at Harvard University and the Massachusetts Institute of Technology. Church highlighted the significance of harnessing natural evolutionary processes, like the ones seen in Chonkus, to help tackle global environmental challenges. With further research and development, Chonkus could become a key player in carbon capture strategies, offering an innovative solution to help reverse the impacts of climate change.
