Alga-lysing bacteria have been paid much attention to in recent years. In this study, the alga-lysing strain P05 which was isolated
from an immobilizing biosystem was immobilized by coke and elastic filler, forming two biological reactors. The removal eciencies
of algae, NH4
+-N and organic matter using the two reactors were studied. The results showed that strain P05 was an ideal algal-lysing
bacteria strain because it was easy to be immobilized by coke and elastic filler which are of cheap, low biodegradability and the simple
immobilization procedure.
