The biological production of ethanol from ethane for the utilization of ethane in natural gas was investigated under ambient conditions using whole-cell methanotrophs possessing methane monooxygenase. Several independent variables including ethane concentration and biocatalyst amounts, among other factors, were optimized for the enhancement of ethane-to-ethanol bioconversion. We obtained 0.4 g/L/h of volumetric productivity and 0.52 g/L of maximum titer in optimum batch reaction conditions. In this study, we demonstrate that the biological gas-to-liquid conversion of ethane to ethanol has potent technical feasibility as a new application of ethane gas.
利用具有甲烷单加氧酶的完整甲烷菌，在环境条件下从乙烷中生物生产乙醇，以利用天然气中的乙烷。研究了包括乙烷浓度和生物催化剂用量在内的多个独立变量，以优化提高乙烷到乙醇的生物转化。在最佳分批反应条件下，我们获得了 0.4 g/L/h 的比产率和 0.52 g/L 的最高浓度。在这项研究中，我们证明了将乙烷生物转化为乙醇的气体到液体的转化作为乙烷气体的新应用具有很强的技术可行性。
