Abstract
Recently, nitrate-nitrogen concentration in groundwater increases gradually. Drinking water including nitrate-nitrogen is possible to cause several human-and animal-health damages. Therefore, efficient denitrification methods have been investigated from all angles. In this study, autotrophic denitrifying bacteria, Paracoccus denitrificans IFO 13301 using H_2 gas as a hydrogen donor was immobilized in microcapsules composed of cross-linked poly (vinyl alcohol) gel. The efficient microencapsulation method was reported and the denitrification ability utilizing the microcapsules was evaluated.
