The exploration of bacteria isolated from pig that have beneficial roles and can be regarded as probiotics are still limited. The study explored the diversity of Bacillus sp. from local pig’s digestive tract. Isolates of Bacillus sp. from parts of the digestive tract such as, small intestines, colon, cecum, and rectum are identified with morphological, biochemical, and molecular assays. This study showed that five isolates possess similar characteristics of genus of Bacillus genus. 16S rRNA analysis showed that these five isolates were identified as B. cereus and B. amyloliquefaciens/B methylotrophicus. In addition, they showed various enzymatic activities such as, amylase, protease, and cellulase. Therefore, this study suggests that B. cereus and B. amyloliquefaciens/B. methylotrophicus could contribute to increase the feed efficiency and productivity
