Resumo

<p>In this research it was evaluated the production of biobutanol by<bold> Clostridium beijerinckii</bold>NRRL B-592 using sweet sorghum juice as carbon source. Operational variables, like pH and initial inoculum size, as well as supplementation of industrial media with yeast extract and tryptone, were evaluated. The maximum butanol obtained was 2.12g kg<sup>-1</sup> using 12.5% of inoculum size, 0.05g 100mL<sup>-1</sup> of tryptone and 0.1g 100mL<sup>-1</sup> of yeast extract and initial pH of 5.5. The main contribution of this research was to show a systematic procedure for development of a low cost industrial media for biobutanol production from sweet sorghum.</p>
