The present study investigates the gut of this earthworm to find the most predominant bacterium harbored inside. Gut contents were extracted and streaked on bacteriological media. The predominant type of colony was identified based on size, pigmentation, form, margin and elevation. Thendifferent colonies were isolated and streaked separately to get pure colonies. The bacteria was subjected to several biochemical tests like Motility test, Gram staining, Methyl Red test, Voges-Proskauer test, Indole production test, Carbohydrate Fermentation test, Catalase test and Starch Hydrolysis test in order to identify the species. The bacterial species identification was done using Bergey’s manual. The bacterial isolates such as Micrococcus spp, Veillonella spp, Bacillus spp and Streptococcus spp were identified. ER -
