Identification of bacteria from mangrove forest in Mamburungan, Tarakan City. Issue 1 (September 2020) - Yulma,
Abstract: Bacteria has a main role in the food chain and waters productivity. Bacteria in the mangrove ecosystem mostly are from litter, sediment, and sea waters. The research objective is to determine the genus of bacteria that was found in Avicennia marina and Sonneratia alba leaf litter as well as bacteria in waters and sediment from a mangrove forest in Mamburungan. The method was designed by using explorative descriptive, and the analysis parameter was the genus. This study was done in the field experimentally with two phases; they were collected of mangrove leaf litter, waters, and sediment, followed by identification of bacteria in the Fish quarantine station, quality control, and safety of Tarakan Class II Fisheries Laboratory. The results showed that seven genus bacteria of Sonneratia alba was found, such as Bacillus, Aeromonas, Listeria, Stapylococcus, Enterobacteria, Bacteroides, Actinobacillus and nine genus of Avicennia marina, they were Bacillus, Listeria, Aeromonas, Pseudomonas, Enterobacteria, Corynebacterium, Actinobacillus, Plesiomonas, Flavobacterium . In sediment, there were ten genus, i.e., Bacillus, Plesiomonas, Enterobacteria, Corynebacterium, Listeria, Aeromonas, Micrococcus, Actinobacillus, Bordetella parapertussis, Clostridium. In sea waters, there were eight genus like Bacillus, Listeria, Aeromonas, Corynebacterium, Micrococcus, Actinobacillus, Pseudomonas, and Enterobacteria . The dominant bacteria that were found in litter, sediment, and sea waters were Bacillus .
