Growth Conditions
The novel bacterium is an obligate chemolithotroph capable of utilizing H2 as electron donor, O2 as corresponding electron acceptor and CO2 as carbon source. Venenivibrio stagnispumantis gains metabolic energy using the "Knallgas" reaction H2 + ½ O2 → H2O. For growth either elemental sulphur (S0) or thiosulfate (S2O32−) is required. Growth is observed under thermophilic conditions between 45 °C and 75 °C (optimum 70 °C), under moderate acidophilic conditions between pH 4.8 and 5.8 (optimum pH 5.4) and under microaerophilic conditions between 1.0% and 10.0% (v/v) O2 (optimum between 4.0% and 8.0% (v/v) O2).

Famous quotes containing the words growth and/or conditions:
“Unlimited economic growth has the marvelous quality of stilling discontent while maintaining privilege, a fact that has not gone unnoticed among liberal economists.”
—Noam Chomsky (b. 1928)
“Purity is not imposed upon us as though it were a kind of punishment, it is one of those mysterious but obvious conditions of that supernatural knowledge of ourselves in the Divine, which we speak of as faith. Impurity does not destroy this knowledge, it slays our need for it.”
—Georges Bernanos (1888–1948)
