These mutated algae could solve the climate change crisis

A new strain of cyanobacteria, informally called “Chonkus,” has been identified in hydrothermal waters off Italy’s Vulcano Island, sparking interest in its carbon capture potential. Discovered during a marine survey aimed at collecting water samples from Vulcano’s shallow volcanic springs, this large cyanobacteria, formally designated strain UTEX 3222, exhibits unique characteristics that could contribute to carbon sequestration efforts.

The hydrothermal environment around Vulcano creates a high concentration of carbon dioxide (CO₂), which is believed to promote the growth of Chonkus. Observations show that the cells of these cyanobacteria develop carbon-rich granules, which accelerate sink rates in marine environments. Scientists believe these adaptations allow Chonkus to absorb carbon directly from its environment, promoting its growth and allowing it to settle in the depths of the ocean, where it stores the captured carbon.

Potential benefits for industrial applications

Chonkus’s ability to form large colonies and store carbon internally is not only valuable in its natural environment; it is promising for industrial applications. By storing carbon more efficiently than other species, Chonkus could reduce energy costs for industries involved in carbon capture by as much as 30 percent. Professor George Church, a leading researcher in health sciences and technology at Harvard University and the Massachusetts Institute of Technology, noted that the discovery harnesses natural evolutionary processes and could potentially help humanity tackle the climate crisis with environmentally efficient means.

Balance between innovation and environmental caution

Although Chonkus exhibits a range of desirable carbon capture properties, researchers recommend cautious application. Large-scale microbial discharges can disrupt existing ecosystems and carbon sequestration may not be permanent if these organisms die. Nevertheless, given its resilience to high temperatures and rapid growth rate, it has potential for various applications in biomanufacturing, especially in environments such as bioreactors.

While there are still challenges to be addressed, this discovery indicates a promising step toward more sustainable carbon capture solutions through naturally occurring microbial adaptations.
