Alternatives to oil based fuels and chemicals are studied to increase energy security and protect of the environment through development of new technologies for the production of synthetic fuels and chemicals using renewable energy sources such as biomass. Gas fermentation is a good alternative to produce energy and chemicals from the bio masses and other industrial waste gas. Previous studies about gas fermentation have been processed in pure culture systems. However, pure culture is vulnerable to contamination and requires high cost for construction and operation; thus, mixed culture systems are required for mass production. The objective of this study is enriching the microbial community for gas fermentation and determined optimum conditions of a bioreactor to process gas fermentation in mixed culture. This study will provide feasibility of mixed culture gas fermentation system and suitable operating factors of the mixed culture bioreactor to mass produce organic acid stably and economically.
