Saccharomyces cerevisiae is a yeast that is rich in protein, carbohydrates and fat, can be used for human consumption. The alternative media can be used as S. cerevisiae growth media, with the condition that the contents in it, meet the requirements of yeast growing media, so it can reduce the use of commercial media. One alternative media is a formula consisting of bean sprouts and several other ingredients. S. cerevisiae growth curves on formula media based on optical density, pH and biomass of yeast, have a 0 to 5th hour lag phase, log phase 5th – 30th hour, stationary phase 30th – 60th hours and death phase 60th- 70th hours. In the death phase at 60th- 70th hours, there was an overhaul of the cell wall. Mannoprotein precipitate produced from yeast cell wall extraction can be used as bioemulsifier. Emulsification activity of mannoprotein from the yeast at the 1st and 24th hour is 50%. The appropriation of S. cerevisiae yeast mannoprotein has an effect on water holding capcity, while cooking loss and tenderness of sausage had no effect.
