Fermentation Process Doubles Production of Attractive Biofuel
A new discovery should make the alternative fuel butanol more attractive to the biofuel industry. Univ. of Illinois scientist Hao Feng has found a way around the bottleneck that has frustrated producers in the past and could significantly reduce the cost of the energy involved in making it as well.
“The first challenge in butanol production is that at a certain concentration the fuel being created becomes toxic to the organism used to make it (Clostridium pasteurianum and other strains), and that toxicity limits the amount of fuel that can be made in one batch. The second issue is the high energy cost of removing butanol from the fermentation broth at the high concentrations used by the industry. We have solved both problems,” he says.
