This species is the type for the genus Fredricksoniimonas. In addition to genus characteristics, the estimated genome size for this species is 2 Mb. The %GC for the genome is 50.78 %. Coupled with a Group A3 [FeFe] hydrogenase encoded by the genome of this species, a reversible acetyl-CoA synthetase indicates likely acetogenesis in this species, through the production of acetate from acetyl-CoA by the fermentation of glucose and nucleotides. Respiratory complex I is present in the genome of this species, and can provide oxidized NAD+ and maintain a proton gradient across the membrane. A respiratory F-type ATPase (complex V) is also present in the genome, and can produce ATP. A metal-reducing cytochrome is present in the genome. Additionally, a "symbiotic" F-type ATPase is also encoded by this genome, along with all genes required for the tight-adherence complex and a Type-4a pilus. A very large ORF is also encoded by this genome. The assembly was recovered from a metagenomic sample of lake water from Nästjärnen, Sweden. The nomenclatural type for the species is the genome GCA_903860135.1.
