This is so inspiring. It has become almost axiomatic that Martian regolith is toxic. [1] This microbe research represents a move in thinking from planetary protection (protecting us from Mars) to In-Situ Resource Utilization (ISRU), using Mars to support us. The microbe turns two liabilities — the high perchlorate ClO4 mineral content and the atmospheric CO2 — into the two necessities for a colony: building material and breathable air.

That reminds of how oxygen itself was highly toxic to the early anaerobic lifeforms on Earth.
