Yes, they can! First proof of bacterial manganese(IV) oxide use for survival near H2S “dead zone”
The Black Sea, with its permanent stratification, large oxygen-free water masses and extensive zones of toxic H2S, is an excellent natural laboratory to study survival strategies of specialised organisms. IOW Microbiologist Jan Henkel and colleagues have investigated how bacteria are nevertheless able to grow there. They now for the first time present proof in the renowned scientific journal PNAS that a bacterium that frequently occurs near the “dead zone” specifically uses manganese(IV) oxide to gain metabolic energy from H2S and convert it into non-toxic sulphate.
