Eksplorasi Bakteri Penambat Nitrogen dari Tanah Hutan Mangrove Sungai Peniti, Kabupaten Mempawah
Abstract
Peniti Mangrove Forest is one of the forests in West Kalimantan that has high forest productivity, thus supporting the presence of nitrogen-fixing bacteria. Nitrogen fixing bacteria is one of the nitrogen-fixing microorganisms that can bind the free nitrogen needed for the nitrogen cycle process. This study aimed to determine the types of nitrogen-fixing bacteria that can be found in the soil of Peniti mangrove forest, Mempawah Regency, West Kalimantan. Taking soil samples used a purposive sampling method. Bacterial isolation used dilution techniques and pour plate method on the Nitrogen Free Bromthymol Blue (NFB) media. The nitrogen fixing was obtained by 3 isolates of nitrogen fixing bacteria. After identification, 3 genera were obtained, namely members of the genera Azotobacter, Azospirillum, and Pseudomonas.
