Exact excerpt

In laboratory experiments lasting 48 hours, Methanothermococcus okinawensis was incubated in simulated Enceladus seafloor mineral-water chemistry. The simulated reactions generated abiotic hydrogen, while the organism remained viable and produced methane under alkaline conditions reaching pH 11. The result concerns a controlled simulation with one methanogen strain, not direct sampling or proof of life on Enceladus.
