Jenis-Jenis Bakteri yang Berasosiasi pada Proses Dekomposisi Serasah Daun Avicennia Marina (Forsk) Vierh Setelah Aplikasi Fungi Aspergillus Sp., Curvullaria Sp., Penicillium Sp. pada Beberapa Tingkat Salinitas di Desa Sicanang Belawan

Abstract

The research on The Variety of Bacteria which Asociated on the Decomposition Process of Avicennia marina Leaf Litter After Aplicated Aspergillus sp., Curvularia sp., and Penicillium sp. in the some Salinity Level had a purpose to know the diversity of bacteria. The research had done at Microbiology Laboratory of FMIPA USU Medan and at the mangrove area of Sicanang-Belawan did began at december 2009 until june 2010. The results of the research indicated that totally 24 species of bacteria which asociated on the decomposition process of Avicennia marina leaf Litter After Aplicated fungus in the some salinity level, including Bacillus (3 species), Sporosarcina (3 species), Planococcus (2 species), Micrococcus (2 species), Pseudomonas (1 species), Escherichia (1 species), Mycobacterium (1 species), Flavobacterium (1 species), Corynebacterium (1 species), Caulobacter (1 species), Staphylococcus (1 species), Klebsiella (1 species), Aeromonas (1 species), Neisseria (1 species), Acinetobacter (1 species), Pleisomonas (1 species), Brevibacterium (1 species) dan Yersinia (1 species). The diversity of species and population of bacteria were the highest at 0-10 ppt and the lowest at 20-30 ppt.
