The Isolation and Identification of Valuable Bacteria for Removal of Nitrogen and Phosphate in Municipal Waste Water

Bacterial strains which have excellent removal capacity of phosphate or reduction capacity of were isolated from waste water. Among isolated strains. WR8 and WR1 strains were showed goood efficiency in removal of phosphate and reduction of respectively. When each strain was cultivated in waste water, WR8 strain removed about 85% of phosphate and WR1 strain reduced about 85% of -N. By the result of investigation of morphological and physiological characteristics, WR8 was identified as Aeromonas hydrophila and WR1 as Klebsiella pneumoniae.
