제목 Effect of tryptone, peptone, sodium sulfide addition on syngas fermentation with Clostiridium autoethanogenum
초록 n recent years, the excessive use of fossil fuels has caused serious climate change problems shch as global warming, and biorefining techologies for producing bioenergy and biocompounds have been attracting attention as an alternative to cope with such climate change. Biorefinery is known as a technology for producing biofuels and biochemicals from biomass using microbial catalysts. The use of gaseous substrates (such as industrial waste gases and synthesis gas) for the biofuel production has some advantages; the reduction of the atmospheric greenhouse effect and economical procedure. Anaerobic acetogenic bacteria shch as Clostridium autoethanogenum and Clostridium ljungdahlii can convert synthesis gas compsoed of 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 we investigated to the effect of nitrogen source such as tryptone, peptone and Na2S∙9H20 on growth and product formation. We concentrate to evaluate ethanol productivity, acetic acid productivity, and ethanol to acetic acid ratio according to individual factor of medium.
