%X The characteristics of cell decay in biological wastewater treatment systems were investigated under aerobic condition, by measuring the decay rate and by determining the death rate with LIVE/DEAD dyeing experiments. It was found that cell decay in biological wastewater treatment systems can be actually described as two parts: decay caused by cell death and decay derived from activity decrease. The experimental results revealed that 60% of cell decay in a nitrifying system was caused by activity decrease and 40% was caused by cell death. In a heterotrophic system, however, activity decrease was responsible for 80% of cell decay, and the other cell decay for 20% was caused by cell death.
