Abstract Cyanobacteria are photosynthetic organisms that play important roles in carbon cycling as well promising bioproduction chassis. Here, we isolate two novel cyanobacteria, UTEX 3221 and 3222, from a unique marine environment with naturally elevated CO₂. We describe complete genome sequences for both isolates and, focusing on 3222 due to its planktonic growth liquid, characterize biotechnologically-relevant biomass characteristics. outpaces other fast-growing model strains solid medium. It can double every 2.35 hours liquid medium grows high density (>31g/L dry weight) batch culture, nearly of Synechococcus sp. PCC 11901, whose high-density was recently reported. In addition, sinks readily, settling more quickly than strains, suggesting improved de-watering biomass. This behavior be explained part by larger cell volume. These traits may make compelling choice Overall, find bio-prospecting environments CO₂ uncover CO₂-metabolizing
