Ca. Electrothrix yaqonensis

Ca. Electrothrix yaqonensis is a newly identified species of cable bacteria, a group known for their ability to conduct electricity through long, thread-like cells.

This electrical conductivity is part of how they transfer electrons across distances within sediment, effectively helping them “breathe” by connecting zones rich in electrons (like sulfides) with those rich in electron acceptors (like oxygen or nitrate).

A few key takeaways from this discovery:

• Naming Honors Indigenous Heritage: The species name yaqonensis pays tribute to the Yaqona people, original inhabitants of the Yaquina Bay area, acknowledging the cultural and historical significance of the land. It’s also notable that members of the Confederated Tribes of Siletz Indians were involved in the naming process.
• Metabolic Hybrid: Genetically, this bacterium is a blend of features from both Ca. Electrothrix and Ca. Electronema, indicating it might represent an evolutionary bridge or hybrid lineage, potentially with unique environmental adaptations.
• Environmental Versatility: Like other cable bacteria, this species likely contributes to geochemical cycles and sediment health, and its discovery in a saltwater estuary reinforces the idea that cable bacteria are ecologically widespread.
