Many microorganisms secrete extracellular biopolymeric flocculants (EBFs) in the culture broth. This work reviews the development of EBF research and applications. Aspects discussed include a comparison of the chemical and biological flocculating agents, isolation of EBF-producing microorganisms, culture conditions, mechanisms of flocculation, the chemical structure of EBFs, and the role of physicochemical factors in the flocculating activity.
许多微生物在培养液中分泌细胞外生物聚合絮凝剂（EBFs）。本文综述了EBF研究与应用的发展情况。讨论的方面包括化学和生物絮凝剂的比较、产EBF微生物的分离、培养条件、絮凝机制、EBFs的化学结构以及物理化学因素在絮凝活性中的作用。
