Mangrove habitats are found in coastal areas and have unique environmental conditions. The mangrove habitat contains abundant and various microbial resources, which play critical roles in mangrove ecosystem maintenance and function. One of the intriguing mangrove habitats to study is the Wonorejo Mangrove, Surabaya. In this current research, the abundance and diversity of bacterial communities in four areas of Wonorejo Mangrove, Surabaya, were determined. The four areas of interest included mangrove by the river with a jogging track (station 1), mangrove by the river without a jogging track (station 2), mangrove in the estuary (station 3), and mangrove in the pond (station 4). Soil samples were collected from the four stations, then the abundance of bacteria was determined by using the Standard Plate Count method. The bacterial colonies that grew from each sample were then listed and characterized based on their colony morphology. The results indicated that the highest abundance was at station 4 with the number of bacteria at 1.83x107 CFU/ml, while the lowest abundance was at station 1 with 5.3x 104 CFU/ml. The structure of bacterial communities of each station was varied. Nevertheless, one of the isolates, namely isolates TS1.1 can be observed in all of the samples. We can conclude that the abundance and the diversity of bacterial communities are affected by environmental factors. This research further deepens our understanding of the bacterial dynamics in Wonorejo mangrove habitats.
