Draft Genome Sequence of Candidatus Phycosocius bacilliformis, an Alphaproteobacterial Ectosymbiont of the Hydrocarbon-Producing Green Alga Botryococcus braunii

Candidatus Phycosocius bacilliformis is an alphaproteobacterial ectosymbiont of the hydrocarbon-producing green alga Botryococcus braunii. We sequenced the whole genome of Ca. P. bacilliformis BOTRYCO-2, isolated from a two-membered culture with B. braunii. The genome contains approximately 3.3 Mb, with an average G + C content of 56.91% and 3,125 predicted protein-coding genes.
