ethanol from syngas fermentation is an indirect fermentation
that utilizes gaseous substrates (mixture of CO, CO2 and H2)
made from industrial flue gases or gasification of biomass, coal or municipal solid
waste. This review article provides an overview of the various biological processes for ethanol production from sugar,
lignocellulosic, and algal biomass. This paper also provides a detailed insight on process development, bioreactor design, and
advances and future directions in syngas fermentation.
