This species is the nomenclatural type for the genus Zapsychrus. The estimated genome size is 2.1 Mb. Based on the description in Williams et al., 2021, an incomplete horse-shoe type TCA cycle is encoded by this genome, and this species is predicted to be heterotrophic. Glucose is predicted to be fermented through the EMP pathway. A Group 3d [NiFe] hydrogenase is predicted from the genome, and a V-type ATPase, respiratory F-type ATPase and Rnf complex for ATP synthesis is present. A reversible acetyl-CoA synthetase may be indicative of acetogenesis in this species. A conductive pilin is also encoded by the genome. All genes for a tight-adherence complex (Tad) and Type-4a pilus are present in the genome. The nomenclatural type for the species is the genome 3300035698_1555, recovered from metagenomic sampling and sequencing of Ace Lake, Antarctica.
