Process Fermentation of Filtrate Bamboo with Saccharomyces Cerevisiae and Zymomonas Mobilis: An Advance Study

Fermentation is the process of the formation of ethanol from glucose by using enzymes. Bamboo is one of the materials containing glucose is high enough, that is previously done hydrolysis in advance. Bamboo used when the hydrolysis process of bamboo that does not include lignin and the pentose done process of pretreatment and not lignification. The purpose of this research is to produce ethanol as a raw material substitution of bioethanol, knowing pentose and dirt left in the bamboo. Therefore, need to be studied in the future, with the best process, that we used biological processes that can optimize the production of ethanol. The use of the enzyme (Saccharomyces Cerevisiae and Zymomonas Mobilis) is also significant because of the optimum enzyme conditions. Temperature, pH, and the yeast with optimal conditions when it can raise the level of his work. The fermentation process at temperature 25°C and 45°C, the filtrate is 500 ml solution of bamboo and the stirring speed of 200 rpm. The variable composed enzyme with a ratio (v/v) of 0.25 to 0.75. Resulting from the fermentation processed can produce ethanol with a yield 30.5% and 36% of the weight of the bamboo. The result of the process of fermentation obtained bioethanol with low ethanol yield of 10-15%, which requires the flash distillation process to obtain yield bioethanol technical 90-95%. The Saccharomyces C. had higher glucose and bioethanol levels results of Zymomonas M., but durability Zymomonas M. stronger in a fermentation process.
