toksilisus

Toksilisus is a term used in speculative biology and science fiction to describe a hypothetical genus of extremophile microorganisms. It is not scientifically described nor are there confirmed isolates. The name is used to explore how life might cope with toxins and silica-rich environments.

In descriptions found in literature, toksilisus cells are imagined as single-celled organisms, typically rod- or coccoid-shaped, with robust cell envelopes suited to high-pressure, mineral-rich habitats. They are conceived as chemoautotrophs that gain energy from the oxidation of reduced inorganic compounds such as hydrogen sulfide or hydrogen and fix carbon dioxide into organic matter.

Habitats include silica-rich subsurface sediments, hydrothermal vent fields, and deep-sea or subsurface aquifers where toxic compounds accumulate. Ecologically, toksilisus is depicted as interacting with mineral matrices, potentially detoxifying certain toxins and contributing to mineral precipitation and microhabitat stabilization. In some scenarios, they are imagined to form symbiotic relationships with other microorganisms or with mineral surfaces.

The term combines a toxin-related root with a stylized taxonomic suffix. It appears mainly in speculative biology and certain works of science fiction as a thought experiment about life's limits and astrobiological potential.
