Experimental studies were conducted to determine the feasibility of autotrophic denitrification with Thiobacillus denitrificans as a nitrate removal process for wastewater. S^0-acclimated activated sludge, which can carry out autotrophic denitrification using S^0 as electron donors, was prepared by the fill and draw cultivation method. The kinetic constants for the S^0-denitrification reaction using S^0-acclimated activated sludge under NO_3-N limiting growth conditions were determined to be Y=0.33 mg-TOC/mg-NO_3-N and b=0.058 d^<-1>. High percentages of denitrification (over 95%) and rates of denitrification ranging from 0.19 to 0.24 mg/NO_3-N/mg-TOC・d were obtained in the continuous denitrification experiments using S^0-acclimated activated sludge.
