Removal of aluminium in contaminated soil using locally isolated vibrio alginolyticus

The aluminium contaminated soil is currently being a concern due to the use of aluminium waste as a material for building roads and river dams in Jombang District, Jawa Timur Province, Indonesia. This application was debated because aluminium waste is categorized as hazardous waste. One widely known method for treating the metal contaminated soil is bioremediation. One potential indigenous bacterial species to remove aluminium, Vibrio alginolyticus was isolated from contaminated soil. A toxicity test to V. alginolyticus showed that this bacterium could grow in aluminium contaminated soil until 100 mg/L equal to 48 mg/kg concentration. The removal of aluminium from soil was conducted by using 50 and 100 mg/L concentration. The result showed that the addition of 2% v/v of V. alginolyticus can remove 5.48% aluminium from 100mg/L contaminated soil initial concentration after 12 days of test period. The addition of V. alginolyticus did not significantly influence the removal of aluminium from contaminated soil (p > 0.05).
