Abstract


The test to the purchase of six yeast as a starting strain of sweet sorghum juice fermentation raw materials to produce fuel ethanol process research:. Followed by a single factor test and orthogonal test, the test yeast suitable for fermentation The combination of conditions: the yeast Danbaoli: temperature of 32 ° C; pH value of 5.03; inoculum size was 1.0 per thousand; the juice brix for 14Brix. Angel Yeast: temperature of 32 ° C; pH value of 5.03; inoculum size was 1.1 per thousand; juice brix 14Brix. LALVIN yeast: temperature of 30 ° C; pH value of 5.03; inoculum size of 1.2 ‰; the juice brix 14 the Brix. 1384 - Weir yeast: a temperature of 32 ° C; pH value of 5.03; vaccination 2ml; juice brix 14Brix. 1347 - Sit watts yeast: a temperature of 33 ° C; pH value of 5.03; inoculation volume of 3ml; juice brix 14Brix. 1416 - Saccharomyces cerevisiae: a temperature of 32 ° C; pH value of 5.03; vaccination 2ml; juice brix 14Brix. 2 through yeast fermentation in the best fermentation conditions, either from fermentation time or from fermented mash Alcohol to compare Danbaoli yeast are dominant. Therefore, Danbaoli yeast six tested predominant strains of yeast. 3. Yeast to Danbaoli as the original strain, its nutrients trial, determined by single factor test and orthogonal test than the applicable amount of nutrients in combination: the combination of nutrients than the applicable amount determined: ammonium sulfate was 0.4%, magnesium sulfate 0.1%, calcium chloride 0.1%, dipotassium hydrogen phosphate is 0.005%. 4 shaker speed of 120rpm conditions, add nutrients in the yeast fermentation time 16h, without adding any nutrients in the yeast fermentation time 18h Therefore, adding yeast nutrient than not add nutrients yeast fermentation time 2h. Alcohol also increased by 0.2%. Followed by a single factor and orthogonal experiments were determined the Danbaoli yeast immobilized more suitable combination: sodium alginate concentration of 2.5%, calcium chloride concentration of 3% PVA concentration of 0.3% silica concentration of 0.3 %, the concentration of aluminum oxide, the immobilization time 7h. 6. Free yeast in shaker speed 120rpm conditions, the fermentation time 18h; immobilized yeast in a shaker at 120rpm conditions, the fermentation time is 13H, therefore, after the free yeast immobilized, fermentation time can be shortened At 5h, ethanol yield of up to 92%. Followed by a comparison of the three active dry yeast direct fermentation capacity found from the alcohol content, residual sugar, the fermentation period to evaluate, Danbaoli yeast fermentation force is dominant. Direct fermentation the optimum temperature fermentation Alcohol or less; sterilization fermentation than directly fermented wine accuracy increased by 0.3%. 9 From the energy point of view, the use of direct fermentation is economically feasible.
