Abstract

Alcohol production for, sugar-cane pieces by EX-FERM technique was studied. with three strains of Saccharomyles cerevisiae in flask experiments. Two types of cane treatment were used Chips and shreded pith, Other fresh on dried after static fermentation for 40 h at 30 °C, the cane was removed, and fresh cane was added to the yeast alcohol broth. After an additional 24 h, the cane was again removed and the liquor was analyzed. After the first 40 h cycle, sugar consumption was above 99% with these strains and ethanol reached levels of 1. 28 to 4. 00 g per 100 ml. The final ethanol concentration reached 4. 25 to 5. 36 g per 100 ml and sugar consumption was above 98% during second EX-FERM cycle employing previously air dried Chips and pith.
