On the other hand, the synergetic effect could be found during BS-UC adding to mixed alkanes culture. Furthermore, BS-UC could increase the hydrophobicity of cell surface and thus enhanced the ability of cell attachment to alkane. Adding BS-UC also increased the Zeta-potential of cell and medium surfaces significantly, i. e. BS-UC could decreased the negative electric charge density of their surface, so the repulsive tension between cell and medium would be weakened and the adsorption of them would be easier. The results of the test with sand filled column for investigating the cell adsorption in pore-medium showed that the residual amount of cell in the column increased with increase of adding BS-UC concentration.
