Metagenome-Assembled Genome of a Novel Cyclobacteriaceae Epibiont of a Heterotrophic Diazotroph.

Here, we describe the metagenome-assembled genome (MAG) HetDA_MAG_SS2, in the family Cyclobacteriaceae . It was found in association with a HetDA cyanobiont isolated from a Station ALOHA Trichodesmium colony. Annotation suggests that HetDA_MAG_SS2 is a chemoorganoheterotroph with the potential for lithoheterotrophy, containing genes for aerobic respiration, mixed acid fermentation, dissimilatory nitrate reduction to ammonium, and sulfide oxidation.
