Tim KOPI Delft
Peunjuk lokasi :
– Lokasi ruangan, lantai 3 gedung sipil (gedung yang warna coklat bukan gedung kaca). Ruangannya ada di pojok arah gedung kaca biru, bukan ke arah gedung arsitek lama.
– Jalan masuk tercepat. Dari tangga gedung kaca (hanya saja memerlukan kartu masuk), atau bisa dari sipil, ambil arah lift A
Kinetics of Biodegradation of Petroleum Contaminated Soil by using
Indigenous Isolated Pseudomonas pseudoalcaligenes, Bacillus megaterium, and Xanthobacter autotrophicus Bacteria
The bioremediation of petroleum contaminated soil was investigated using a microscale Landfarming. The Indigenous bacteria, Pseudomonas pseudoalcaligenes, Bacillus megaterium, and Xanthobacter autotrophicus were isolated from the contaminated sites Sungai Lilin Jambi Pertamina Ltd and used further in the bioremediation experiments. The biodegradation rate of petroleum contaminated in soil in the presence of the isolated bacteria were studied by using the chemical kinetics approach. The reaction orders were studied by using the differential method and the reaction rate constants were studied by using the integral method. The results showed that the reaction orders were 0.63 .Pseudomonas pseudoalicaligenes 0.52 (Bacillus Megaterium) 1.35 (Xanthobacter Autotrophicus) , and the reaction rate constants were -0.0189, -0.0204, -0.0324 %/day respectively. Considering the value of reaction orders and reaction rate constants, the biodegradation rate of contaminated soil by using each bacteria has significantly different value; Xanthobacter Autotrophicus bacteria could degrade the petroleum oil sludge fastest than the others.
