<p>The present invention provides an immobilized cell aggregate. A cell with lowered cell activity or dead cell in the immobilized cell aggregate can drop out from the immobilized cell aggregate due to loss of cohesive or adhesive activity. Therefore, only living cells can remain in the immobilized cell aggregate. By using the immobilized cell aggregate, a desired material can be efficiently produced and environmental pollutants can be efficiently decomposed. The cohesiveness or adhesiveness can be obtained by incorporating genes. Moreover, by introducing genes for secretion and production for a desired material into cells of immobilized cell aggregate, the desired material can be efficiently produced.</p> |
