| Abstract: | The effect of Eh on the methanogenesis of methanol by Methanosarcina barkeri strain Fusaro was studied in pH-controlled anaerobic batch cultures at 37°C, in which the Eh of the culture medium was controlled by the addition of Ti(III)-citrate at values ranging from ?340 to ?520 mV. The changes in Eh revealed that the specific growth rate, μ, specific methane production rate, QCH4 and growth yield, YX/S were optimum under an Eh between ?430 and ?520 mV, while they decreased at the higher Eh of ?340 mV. The maximum values of QCH4 and μ under the optimum Eh condition were 210 ml CH4/g dry cell weight·h?1 and 0.11 h?1, respectively. |
