Abstract

Uji Potensi Kultur Tunggal dan Kultur Campur Bakteri Rizosfer Salvinia molesta D.S. Mitchell pada Bioremediasi Limbah Cair Minyak Bumi telah dilakukan pada bulan Maret-September 2013, pengambilan sampel berupa sludge diambil dari PT. Pertamina RU III Plaju, sedangkan uji potensi kultur tunggal dan kultur campur dilakukan di Laboratorium Mikrobiologi Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Sriwijaya. Penelitian ini bertujuan untuk mengetahui potensi kultur tunggal dan kultur campur bakteri rizosfer pada proses bioremediasi. Hasil penelitian ini rata-rata jumlah sel bakteri Acinetobacter sp. tinggi sebesar 2,6 x 1016 cfu/mL dan Azotobacter sp.2 menunjukan rata-rata persentasi degradasi hidrokarbon minyak bumi tinggi sebesar 96,76% selama 7 hari pada uji potensi kultur tunggal dengan laju degradasi 13,82% per hari. Rata-rata jumlah sel bakteri yang tertinggi pada kultur campur C + E (Alcaligenes sp. + Aeromonas sp.) sebesar 1,4 x 1018 cfu/mL. Kultur campur A + D (Azotobacter sp.l + cinetobacter sp.) menunjukan rata-rata persentase degradasi hidrokarbon minyak bumi tinggi sebesar 99,05% selama 7 hari dengan laju degradasi 14,15% per hari, sedangkan yang terendah C + D (Alcaligenes sp. + Acinetobacter sp.) sebesar 94,13% dengan laju degradasi 13,44% per hari.
