제목 | Culture conditions to improve productivity in Clostridium autoethanogenum culture |
초록 | Biofuels are a sustainable alternative to tackle the challenges derived from the utilization of non-renewable fossil fuels as and energy source such as global warming. The use of gaseous substrates for the biofuel production has some advantages; the reduction of atmosphereric greenhouse effect. Absolute anaerobic acetogenic bacteria such as Clostridium autoethanogenum can convert synthesis gas composed to CO, CO₂, and H₂ to ethanol and acetic acid. In this study, we used Clostridium autoethanogenum as biocatalyst for conversion from synthesis gas to bioethanol and acetic acid. We investigated to the effect of culture medium components such as D-Ca-pantothenate ,vitamin B₁₂on growth and product formation. We also tried to evaluate productivity by changing the culture temperature during the stationary phase (after 6 days culture). Ethanol productivity, acetic acid productivity, and ethanol to acetic acid ratio were compared according to individual operating factor. |
