Abstract

By using autoradiography and phosphate medium, high phosphate accumulating bacteria were isolated from the soil of protected cultivation area and activated sludge. Selected strain, PO8, was gram-negative, rod/spherial(0.5~0.6$\times$1.0~1.2${\mu}{\textrm}{m}$ in size) and non-motile. PI4, another selected strain, was gram-negative, rod(0.4~0.5$\times$1.5~1.6${\mu}{\textrm}{m}$ in size) and motile. It also had flagella. According to their morphological, physiological and biochemical properties, the stains were identified as Acinetobacter lwoffi PO8 and Chromobacterium lividum PI4, respectively. A. lowoffi PO8 and C. lividum PI4 cultured in the P-1 medium containing 150ppm phosphate were able to uptake high phosphate up to 92% and 85%, respectively after 24 hours at 3$0^{\circ}C$ during liquid culture.
