摘要：Colony morphology yeast isolates from tuak and its application in producing ethanol from sugarcane bagasse has been conducted. Yeast isolates used in this work were HT4,HT5,and HT20 obtained from Tuak. These isolates have cream to yellow in color,spherical to oval in shape,and grow as budding cells. Our goal is to find yeast isolates used as microbial agent in fermentation process producing ethanol from lignocellulosic biomass as raw material. Based upon morphology showed that these isolates were Candida species. Isolate HT5 then used to see its potent as agent in bioethanol production. Fermentation of 5 g sugarcane bagasse substrate resulted 0.0008% ethanol. This results indicated that isolate has a potent as microbial agent for fermentation,however the optimum condition of process is needed to furthermore study..
