【 摘 要 】

Uca spp, found in mangrove areas, has a role in sediment reworking by making a burrow for air circulation. The nutrient content remains stable and sediment fertility for vegetation growth is maintained. Uca spp has the feeding behavior of eating the residue of plants, separating the detritus and microbes and removing the residue of the plant. The presence of bacteria in the mangrove ecosystem has an important place in the decomposition of the mangrove leaf litter into organic material, used as a source of nutrients for mangrove forest organisms. This study aims to determine the composition of bacteria in the digestive tract ofUca spp., after the consumption ofA. marinaleaf litter. The results of the bacterial identification shows that the bacterial composition contained in Uca spp 's digestive tract is Acinetobacter sp. and Actinobacillus sp, which are bacteria contained in the leaf litter ofA. marina.
