JARAMILLO OBANDO, Juan Jacobo  and  CARDONA, Carlos Ariel. Analysis of the production of biobutanol in the acetobutilyc fermentation with clostridium saccharoperbutylacetonicum N1-4 ATCC13564. Rev.fac.ing.univ. Antioquia [online]. 2011, n.58, pp.36-45. ISSN 0120-6230.

The conditions and characteristics of biobutanol production in ABE fermentation were studied. A cell growth kinetic model structured according to the proposed metabolic pathway Embden-Meyerhof-Parnas (EMP) pathway for the Clostridium Saccharoperbutylacetonicum N1-4 ATCC13564 reaction scheme was used in a continuous flow stirred tank. A sensitivity analysis and optimization based on the decision variables butanol productivity, glucose to butanol yield and glucose global conversion for different feed concentrations and dilution rate were performance. Productivity values of 27,46 mM h^-1, yield of 0,65 mmol of butanol per mmol of glucose and final conversion of 95,38% at optimal food concentration of 295 mM and optimal final dilution rate of 0,15 h^-1 were obtained.

Keywords : Biobutanol; ABE fermentation; Embden-Meyerhof-Parnas (EMP); Clostridium saccharoperbutylacetonicum N1-4 ATCC13564.
