Both the removal efficiency of the Eichhornia crassipes dried straw-immobilized bacterial consortium and shifts in soil bacterial community in response to the strategy were unmasked in this study. After 30 days of , total petroleum ;in soil was determined and immobilized consortium showed a removal percentage (51.7%) better than either Eichhornia crassipes dried powder (37.0%) or bacteria solution (36.0%) alone. Bacterial community and analyses demonstrated that the of Cytophagales and Rhizobiales increased with increasing and total nitrogen contents because of the addition of Eichhornia crassipes dried powder. The genus Burkholderia which may play a key role in hydrocarbon degradation among the inoculated bacterial consortium proliferated when immobilized on the Eichhornia crassipes dried powder. Such a cell immobilization technology using materials as carriers helps to improve and mitigate competition between indigenous and inoculated microorganisms for nutrients, which offers a promising way to enhance the removal of crude oil from .
