Fermentação Alcoólica Do Caldo Da Cana: Parâmetros Operacionais De Resposta No Processo

Abstract: RESUMOAtravés da constante busca pela redução da dependência do petróleo para fins energéticos, associados aos benefícios ambientais e sócio políticos, destaca-se o etanol como o biocombustível com maior capacidade de inserção no mercado, devido principalmente a variedade de matérias primas renováveis com características químicas capazes de sintetizar esse combustível, e também pela relativa facilidade de operação do processo bioquímico adotado para a produção, definido como fermentação alcoólica. Dessa forma … Show more

“…The increase or decrease in absorbance is related by the presence of microorganism in the medium, however, this cell concentration includes both living and dead cells. 27,33 For assays A and B, the addition of the inoculum resulted in high absorbance values in 600 nm, with a slight decrease observed over time. For assay B, there was a decrease to 0.922 absorbance value after 120 min, after which the absorbance remained stable until the end of the assay.…”

“…The McFarland scale of turbidity in liquid culture media is used to determine the rate of multiplication of microorganisms, because an increase in bacteria causes turbidity or opacity in the medium, hence hindering the passage of light. The increase or decrease in absorbance is related by the presence of microorganism in the medium, however, this cell concentration includes both living and dead cells 27, 33 …”

“…Hansen, em condições de anaerobiose. Os principais parâmetros que influenciam no processo de fermentação alcoólica são o pH, a temperatura, a concentração celular, os açúcares redutores totais (ART) e o tipo de reator, os quais podem ditar o ritmo e a efetividade da conversão da matéria-prima em produto (PASCHOALINI; ALCARDE, 2009;RIBEIRO et al, 2015).…”
