Abstract :

n order to take advantage of residues generated in coffee industries, Coffee mucilage was used as substrate to produce bioethanol. The microorganism used for the fermentation process was Sacharomyces 

cerevisiae. Batch fermentation experiments were carried out with 20 tests using central composite design with 5 levels 
leadings to evaluate the effect of pH, temperature and initial sugar, respect to yield in the carbohydrates conversion 
to bioethanol. The best condition in the tests was: pH 5.5, temperature 28 ºC, initial sugar 35 g, sugar consumed 98% 
and bioethanol produced 10.93 g, with yield 0.32 g ethanol per gram of sugar and 0.025 g ethanol per gram of coffee 
mucilage.
