Mechanism of water extraction from gypsum rock by …
which gypsum rocks from the Atacama Desert, Chile, provide water for its colonizing microorganisms. We show that the microorganisms can extract water of crystallization (i.e., structurally ordered) from the rock, inducing a phase transformation from gypsum (CaSO 4·2H 2O) to anhydrite (CaSO 4). To investigate and validate the water extraction
