Diversity of Bacteria in Sediment From Mangrove and Bekantan Conservation Area (Kkmb) in Tarakan City

Abstract

Bacteria in sediment plays an important role in various biochemical processes in the waters area, for instance degradation of organic matter, biogeochemical cycle, controlling ammonium, nitrates and nitrites concentration, food source for fauna, primary production, and pollution remediation. The purpose of this study was to determine the diversity of bacteria (Genus) in sediment on the Mangrove and Bekantan Conservation Area (KKMB), Tarakan City. The method used was explorative descriptive method with genus identification as parametric test. Bacterial identification parameters were tested using Gram-test, main test and further test was carried out at the Laboratory of Fish Quarantine, Quality Control and Safety Fishery Products Class II Tarakan. The bacteria found in the sediments on the KKMB were 16 genera i.e. Enterobacteria, Eubacterium, Listeria, Actinobacillus, Bacteriodes, Streptococcus, Plesiomonas, Corynebacterium, Pseudomonas, Aeromonas, Bordetella parapertussis, Micrococcus, Staphylococcus, Clostridium, Neisseria, and the dominant numbers found was Bacillus.

Culturable Cellulolytic Bacteria From Mangrove With Anadara Granosa Cultivation In Sukal, West Bangka

“…Bacillus megaterium is a bacterium that is often found in mangrove areas. B. megaterium is found in the mangroves of Rhizophora apiculata and Sonneratia alba from Mangrove Coastal Waters of Kraton, Pasuruan [13] and the mangroves of Tarakan City [14]. B. megateriumidentified has high extra-cellular enzyme activity to break down the cellulose up to 216 U / ml [15].…”

Isolasi Dan Karakterisasi Bakteri Resisten Cd Dari Kawasan Penambangan Timah

“…Hal ini tergantung pada aktivitas bakteri dalam menghilangkan efek racun dari logam berat pada daerah yang terkontaminasi. Kemampuan resistensi bakteri terhadap suatu logam berat juga dapat dipengaruhi oleh beberapa faktor, diantaranya konsentrasi logam berat, jenis bakteri, dan pH (Perdana, 2012;Zarkasyi, 2008) Tarakan (Yulma et al, 2019).…”

Karakteristik Morfologis dan Fisiologis Bakteri Endofit dari Akar Napas Tumbuhan Avicennia marina (fork) vierh di Mempawah Mangrove Park

“…Bakteri yang memiliki kemampuan tumbuh optimal pada media dengan kandungan 20-30% NaCl dikategorikan sebagai bakteri halofilik ekstrem (kadar garam tinggi). Yulma et al, (2019) genera Neisseria mampu tumbuh pada kisaran salinitas 27-30%. Pada penelitian Yulma et al, (2018) salinitas 21-30% ditemukan bakteri genera Micrococcus.…”

“…Menurut Waluyo (2008) mikroba digolongkan menjadi 3 golongan berdasarkan pH optimal untuk pertumbuhannya, yaitu mikroba asidofilik (pH 1,0-5,5), neutrofilik (pH 5,5-8,0), dan alkalinofilik (pH 8,5-11,5). Yulma et al, (2019) pada pH 6,5-7,8 ditemukan bakteri genera Neisseria. Liu et al, (2007) genera Micrococcus tumbuh pada pH 5-9.…”
