A review research of assimilable organic carbon bioassay

Assimilable organic carbon (AOC) is one of the important parameters internationally recognized to assess the biostability of water. Studies at home and abroad on the AOC bioassay’s development are reviewed from three aspects, including the selection of bacterial species for the bioassay, the optimization of inoculation method and incubation condition of water samples, and the evolution of bacterial growth measurement. The relationships between MAP (microbially available phosphorus), BRP (bacterial regrowth potential), and AOC are compared from determination mechanism. Moreover, the new development trend of AOC bioassay is predicted.
