5.結(jié)論

本系統(tǒng)研究首次加深了我們對(duì)添加SPC后受污染沉積物的內(nèi)部生化過(guò)程和微生物群落結(jié)構(gòu)（包括分類組成、功能預(yù)測(cè)和代謝活性分析）的理解。我們發(fā)現(xiàn)產(chǎn)生了溶解物質(zhì)，提高了微生物群落的活性。此外，添加SPC后，微生物群落結(jié)構(gòu)表現(xiàn)出劑量依賴性偏差。這表明在生態(tài)工程中應(yīng)考慮使用SPC劑量，因?yàn)檫@對(duì)于降低原位修復(fù)成本至關(guān)重要。本研究為SPC在生態(tài)工程中的應(yīng)用提供了有價(jià)值的參考。
