Abstract

Sugar cane juice fermentation by Z. mobilis CP4 subject to stress by ethanol and high concentration of sucrose was investigated. Supplementation with saponifiable portion of soybean oil deodourising destillate (SOD) at 5; 10 and 15 mL/L.The ethanol production resulted values of 15.91; 16.99 and 15.63 g/L respectively. Values of Yp/s 0.35; 0.36 and 0.37 were achieved, which represented 20.69; 24.14 and 27.59% respectively higher when unsupplemented medium fermentation was carried out.Este trabalho investigou a fermentação de caldo de cana-de-açúcar por células de Z. mobilis submetidas ao estresse pelo etanol e elevada concentração inicial de sacarose. Foi utilizado como suplementação a porção saponificável do destilado da desodorização de óleo de soja (SOD) nas seguintes concentrações: 5, 10 e 15 mL/L. Os valores de produção de etanol foram respectivamente: 15,91; 16,99 e 15,63 g/L. Os valores de Yp/s foram: 0,35; 0,36 e 0,37, os quais representam respectivamente: 20,69; 24,14 e 27,59%, superiores daquele cujo meio não foi suplementado.
