The formation of assimilable organic (AOC) in nokdong riverwater in korea and the determination of AOC with acinetobacter calcoaceticus

摘要

The effect of ozone application in Nokdong riverwater on the production of assimilable organic carbon (AOC) was evaluated. The procedure to determine AOC is based on the van der kooij method of bacterial growth measurement by colony forming units. The bacterial indicator species used for this study is Acienetobacter calcoaceticus which was isolated and identified from the ozonated drinking water. Within a sort incubation time, this organism was found to replicate well on acetate and oxalate a s a sole carbon source. The yield value of this organism for acetate and oxalate are 4.9 x 10~(-6) cfu/ug -C and 6.9 x 10~6 cfj/ ug -C, respectively.
