Interaction Between Typha domingensis and Bacteria Bacillus sp. to Treatment of Wastewater Polluted by Kerosene

Abstract

Water pollution with Kerosene is considered as a serious environmental problem in Basrah. Typha domingensis was used to treat kerosene-contaminated water in the construction wetland system. The Isolated bacteria was the most efficient in degradation Kerosene. Bacteria isolated from contaminated water by hydrocarbons of four stations in Basrah, these isolates were tested to show efficiency in degrading hydrocarbons to be used in phytoremediation of water contamination with hydrocarbons. Twelve bacterial isolates were identified as Bacillus sp. The Isolated bacteria (B11) was the most efficient in degradation oil hydrocarbons based on these used in the phytotoxicity test. The phytotoxicity experiment was conducted for 72 days in two glass basins containing water contaminated with 5% kerosene concentration with T. domingensis. The Isolate bacterial were added to two glass basins to test the interaction of the bacterial degradation with the plant and two contaminated ponds without plant and two with pollutant and bacteria without plant with control basin free from pollutant, the temperature between (20.6-36.2)°C, dissolved oxygen between (2.5-7.4) mg / L. The rate of kerosene removal from the water contaminated in the ponds of the plant without bacteria and plant with bacteria, bacteria only and control (76.5%), (81.9)%, (74.1%), (57.4) respectively.
