‘Choncous’ algae found off Italian coast hold promise for climate change recovery

A new strain of cyanobacteria, informally known as “Choncas”, has been identified in the hydrothermal waters of Vulcano Island, Italy, sparking interest in its potential for carbon capture. Discovered during a marine study aimed at collecting water samples from Vulcano’s shallow volcanic vents, this large cyanobacteria, formally designated as strain Utex 3222, exhibits unique characteristics that aid carbon sequestration. Can contribute to the efforts.

The hydrothermal environment surrounding the volcano provides high carbon dioxide (CO₂) concentrations, which are believed to enhance the growth of Choncas. Observations show that the cells of this cyanobacteria grow carbon-dense particles, which accelerates the rate of its sinking in marine environments. Scientists believe that these adaptations allow Choncus to absorb carbon directly from its environment, fueling its growth and leading it to settle in the depths of the ocean, where it can store the captured carbon. Stores.

Potential benefits for industrial applications

The ability of Choncus to form large colonies and store carbon internally is not only valuable in its natural surroundings; It holds promise for industrial applications. By storing carbon more efficiently than other strains, Choncus can reduce energy expenses by up to 30 percent for industries involved in carbon capture. Professor George Church, a leading health sciences and technology researcher affiliated with Harvard University and the Massachusetts Institute of Technology, said the discovery unearths natural evolutionary processes that could potentially help address the climate crisis through environmentally efficient means. Helps humanity.

Balancing innovation and environmental care

While Choncus exhibits a range of desirable traits for carbon capture, researchers recommend cautious application. Large-scale microbial releases could disrupt existing ecosystems and carbon retention may not be permanent if these organisms die out. Nevertheless, given its resilience to high temperatures and rapid growth rates it has potential for various biomanufacturing uses, particularly in settings such as bioreactors.

Although there are still challenges to be overcome, this discovery signals a promising step toward a more sustainable carbon capture solution through naturally occurring microbial adaptations.
