Cyanobacteria are nature's little alchemists – Braden Tierney

"Best-practices to select top strains, to cultivate them at large scale, including maximising the amount of CO2 that is absorbed, and then to harvest the biomass, are challenging and vary drastically between strains and locations." Some companies have already started implementing systems to capture CO2 using microbes. In the US, LanzaTech uses bacteria to convert CO2 into aviation fuels and chemicals used in products ranging from laundry detergents to perfumes. UK company CyanoCapture is using cyanobacteria to produce biological oils and biomass.
