The vertical distributions of dissolved organic carbon (DOC) and manganese were studied in Lakes Fukami-ike and Suigetsu-ko in detail. An accumulation of particulate manganese and a decrease of DOC were found at the boundary of the oxic and anoxic layers in both lakes. It was confirmed that DOC absorption on the particulate manganese and the pure chemical oxidation by the particulate manganese had made almost no contribution to DOC decrease. The reduction of the particulate manganese was found to be associated with the increase of dissolved manganese and the decrease of DOC or glucose which was added in advance. However, it was suggested that the manganese reducing bacteria have only a partial role in DOC decomposition and that the other role was by other heterotrophies.
