Scientists find CO2-eating algae strain, could help in ocean decarbonization | This strain sinks easily in water, making it an excellent candidate for carbon sequestration projects and the bioproduction of valuable commodities.


Researchers from the US and Italy discovered a new cyanobacteria strain, 'Chonkus,' and highlighted its exceptional CO2-absorbing abilities.

An international team of researchers from the United States and Italy has identified a new strain of cyanobacteria, or algae, found in volcanic ocean vents. Most interestingly, Chonkus rapidly settled into a dense pellet resembling “green peanut butter” at the bottom of its sample tubes while other strains remained suspended. Several products, such as omega-3 fatty acids, the antioxidant astaxanthin, and spirulina, are currently manufactured in algae, but they could be made more efficiently in a strain that grows quickly and densely.
