In order to increase biological activities of Co~nebacteriumpseudodipI~t~~eriticum W3712 which degrades achemical softener (organopolysiloxane), the cells were immobilized on four immobilizing carriers by physicaladsorption. The cells immobilized on bentonite had higher removal efficiency than those immobilized onthe other carriers, and physical adsorption of organopolysiloxane on bentonite was 62.5%. The immobilizedcells were produced by 16 ml of culture broth with 20 g of bentonite, and 100 ml of the standard wastewatercontaining 12.000 mgll COD," with organopolysiloxane was removed 95.0% by 10.0 g of the immobilizedcells treatment at room temperature for 10 days by static culture.y static culture.
