The aim of the research was to obtain the best concentration of ergosterol supplemented in a very high gravity fed batch fermentation of bioetanol form Nypa sap. Tween80 and ergosterol play a role as surfactant and nutrition for Saccharomyces cerevisiae to produce ethanol on very high gravity fed batch fermentation from Nypa sap. The exploration research used four treatments with duplicate meas…
