Abstract

Bioremediation is one of kind method which use of bacteria to degrade of hydrocarbon to be another compound. This study aims to get isolation of indigenous bacteria and potential test with Gordonia terrae on diesel oil bioremediation. The water sample was taken from Tanjung Perak Port of Surabaya, Indonesia where contaminated with diesel oil. Analysis of in-situ water quality parameters were consist of Dissolved oxygen, temperature, pH, salinity. Strain isolate bacteria were isolated by Bushnell-Hass medium. The bacterial density result shows in IN6 shows that bacterial density increased up to 9 × 108 cells/ml at day 2 incubation and decrease up to 1.79 × 108 cells/ml at final incubation, IN8 increased up to 8.6 × 108 cells/ml, then decrease up to 3.57 × 108 cells/ml. While, EX8 increased up to 9.1 × 108 cells/ml, and then decrease up to 3.06 × 108 cells/ml. While, results of degradation diesel oil hydrocarbon show treatment IN6, TPH values showed a decrease in the initial hydrocarbon concentration of 30 ppm to 16 ppm. IN8 TPH value shows a decrease in the initial hydrocarbon concentration of 30 ppm to 16 ppm. EX8 TPH value shows a decrease in the initial hydrocarbon concentration of 30 ppm to 24 ppm. In this experiment was found that Bacillus cereus was effectively degrading of diesel oil and can be agent bacterial for bioremediation.

Abstract

The bioremediation system can be improved by using specific bacterial potential as oil-degrading bacteria which microorganisms can use hydrocarbons as a carbon source for their metabolic processes. The aim of this study is to identify R. erythropolis on degradation oil contamination and to obtain indigenous bacteria as new agent bacteria on bioremediation of oil contamination. The polluted water samples from used oil were taken from PPN Prigi, Trenggalek, East Java, Indonesia. The parameters considered were the detection and characterization of indigenous bacteria that degraded used oil. The density of bacteria was analyzed in the interval time of days 0, 2, 4, 6 and 7 and TPH was analyzed at final incubation. The results of this study indicate that the effectiveness of reducing oil concentration was used in testing the potential of bacteria from the highest was Pseudomonas aeruginosa which as indigenous bacteria isolated from water contaminated sites with application cell rate 1×108 cells/ml. It reduced of oil concentration up to 53%, and 1×106 cells/ml reduced oil concentration up to 47%. While, R. erythropolis with application cell rate 1×108 cells/ml reduced 47%. This result was found that Pseudomonas aeruginosa was effectively removed of oil concentration.
