The peat ecosystem area has the potential for bacteria that have the potential to act as nitrogen fixers. These bacteria can be applied in various human activities. In fishery activities, nitrogen is an essential component for plankton growth as a live feed. Besides, the ideal N and P components will affect the abundance of plankton in the waters. In this study, the Isolation of candidate bacteria from the peat ecosystem area under palm tree vegetation was carried out in Trumon District, South Aceh. Different depths in the sample soil are an essential parameter, namely the depths of 0-15 cm, 15-30 cm, 30-50 cm. The isolation method was carried out with a scatter plate using Jensen media and obtained 25 isolates which were bio fertilizer candidates. Biodiversity analysis was also carried out to test the three soil depths of the isolated source. A depth of 15 cm shows an isolate diversity pattern that is almost the same as a sample depth of 30 cm.
