【摘要】 胞外聚合物是微生物通过新陈代谢、细胞自溶形成的有机多聚物，在自然界中广泛存在，且作为一种高效的吸附作用剂，具有良好的可生物降解性，对生态环境影响较小。近年来，在生态学领域已经有了广泛的应用。本文主要从胞外聚合物特性、作用机理、生态学应用等几个方面进行综述。更多还原

【Abstract】 Extracellular polymers(EPS) are organic polymers formed by microorganisms through metabolism and cell autolysis.They are widely present in nature and serve as efficient adsorbents with good biodegradability and environmental-friendly. In recent years, it has been widely applied in the field of ecology. This article mainly revi ewed the characteristics, mechanism of action, and ecological applications of extracellular polymers.更多还原
