Sugarcane bagasse (Saccharum officinarum L.) is a readily available waste product of cane-sugar processing. The major components of bagasse are cellulose and hemicellulose. The objective of the research was to produce bio-ethanol from hydrolizate of sugarcane (Saccharum officinarum L.) bagasse which hydrolyzed by combination of acid and enzymeand further fermented by three types of microorganisms, respectively P. stipitis CBS 5773, or S. Cerevisiae D1/P3GI, or Z. mobilis 0056 FNCC. The experiment employed descriptive analyses in triplicates. The result were as follows: effectiveness of Z. mobilis 0056 FNCC was highest for producing bio-ethanol, respectively 18.99 g/L within 3 hours. S. cerevisiae D1/P3GI produced 17.05 g/L bio-ethanol within 12 hours, and P. stipitis CBS 5773 13.03 g/L bioethanol within 24 hours.
