Sugar cane juice fermentation by Zymomonas mobilis CP4 subjected to inhibition by ethanol and high initial concentration of substrate

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.
