Bacillus sp is a type of bacteria that can be used as a probiotic agent because of its ability to degrade organic compounds for the sake of growth . This study aims to determine type appropriate media types for the growth of probiotic bacteria Bacillus sp . The method used in this research that completely randomized design (CRD) with 4 treatments and repeated 4 times. The treatments were the addition of soy extract, sprouts, and potatoes. The results showed that there were significant differences on each treatment with the addition of soy extract, sprouts, and potatoes in the probiotic culture medium. The conclusion of this study indicate that the type of media that is most optimal to extract the green bean sprouts reach a value of OD (Optical Density) 0.68.
