Because of rapid development of petroleum-based industry, there are many negative effects: decrease of reserve of petroleum and environmental pollution. Bioethanol has been recognized as a promising alternative energy source. Synthesis gas (syngas) can be produced by the gasification of biomass at high pressure and temperature, and also it is utilized by microorganisms that can transform syngas into biochemical feedstocks such as fatty acids and alcohol. The main purpose of this research is to isolate ethanogenic acetogens from environmental samples. In the research, a gas-lift syngas fermentation system was used for microbial isolation. The gas-lift syngas fermentation system has enhanced overall volumetric gas mass transfer coefficient (kLa) by installing sintered glass filter 1). Four animal feces (cow, rabbit, chicken, and goat) were used for microbial source for isolation 2). Successful enrichment of syn-gas utilizing microbial consortia was constructed using all inocula within 2 weeks. Hungate technique was employed to cultivate and isolate putative syn-gas utilizers. As a result, 18 isolates were isolated and identified by 16s rRNA gene sequence for clarifying dominant strain in animal feces. Hence, our present research, using gas lift syngas fermentation system, could be utilized into isolation of ethanogenic acetogens from various environmental sources.
