Extracellular biopolymer flocculants (EBFs) are flocculating substances, consisting of polysaccharides, proteins, and lipids, which are secreted in the culture broth by many microorganisms. Some of EBFs have attracted much attention as biodegradable and nontoxic substitutes for conventional chemical flocculants. This paper reviews the recent development of EBFs. Aspects discussed include an introduction to conventional chemical flocculants and EBFs, isolation of novel bioflocculant-producing microorganisms, culture conditions, chemical structure and molecular weight of EBFs, the physico-chemical factors affecting flocculating activity, fermentation process design and recent and emerging application fields of EBFs.
胞外生物聚合物絮凝剂（EBFs）是由许多微生物在培养液中分泌的一种具有絮凝作用的物质，由多糖、蛋白质和脂类组成。有些 EBFs 作为可生物降解和无毒的传统化学絮凝剂替代品而备受关注。本文综述了 EBFs 的最新研究进展。讨论的方面包括：传统化学絮凝剂和 EBFs 的介绍、新型产生物絮凝剂微生物的分离、培养条件、EBFs 的化学结构和分子量、影响絮凝活性的物理化学因素、发酵工艺设计以及 EBFs 的最新和新兴应用领域。
