Taxonomy

Description
This is a Patescibacteria group bacterium that is a symbiont of the microalgae Nannochloropsis oceanica strain IMET1 and Tetradesmus obliquus strain HTB1. Both microalgae are grown with 10% CO2 in our laboratory for carbon mitigation research. This bacterium was found at the 1 L and 500 L scale and has a genome size of 578,798 bp. It is a dominant bacterium based on relative abundance of the 16S rRNA gene at both scales regardless of whether the algae are bubbled with 10% CO2 or ambient air. Its hyper reduced genome suggests its symbiosis may be obligatory.
