研究成果の概要（英文）： In this study, we aim to develop a tool similar to “hidden metabolic syndrome diagnosis” that can detect organic pollution progression in marine aquaculture sediment at an early stage. We found that aquaculture increased the proportion of fermentative bacteria such as Bacteroidia, Clostridia, Spirochaetia, Fusobacterilia and Bacilli in the seabed sediment. The bacterial community structure in the sediment of “critical area “where organic pollution has already progressed showed a high correlation with sulfide and water content. However, the bacterial community structure in the sediment of healthy and/or moderately eutrophicated areas showed a high correlation with the number of viable lactic acid bacteria, succinic acid and total organic acid concentration. In conclusion, we propose a simple tool to evaluate sediment deterioration in non-critical aquaculture sites by measuring the amount of easily detectable live lactic acid bacteria that act as a marker of deterioration., 研究種目：基盤研究(C); 研究期間：2018～2021; 課題番号：18K05798; 研究分野：水産微生物学; 科研費の分化・細目：, application/pdf},
