Selection and In-Vitro Potentials of Amylolytic Yeast from Several Ragi Tapai in West Sumatra Province

Ragi Tapai is a starter used for the fermentation of cassava and glutinous rice to produce conventional fermented products, such as in Indonesia. contains several enzymes microbes that help process. The purpose this study was identify most potential amylolytic yeast in-vitro (amylolytic, cellulolytic, fermentative). GPA, YEA, APB, CMCA, GPACaCO3 were medium selection characterization. result showed seven samples West Sumatra (Padang, Padang Pariaman, Batusangkar, Panjang, Payakumbuh, Solok, dan Pesisir Selatan), there three including genera Schizosaccharomyces (1 2) 1 genus Trichosporon. In-vitro potential, Trichosporon have amylolytic, fermentative potential. Genera has greater than 2
