Many microorganisms secrete extracellular biopolymeric flocculants (EBFs) i
n the culture broth. This work reviews the development of EBF research and
applications. Aspects discussed include a comparison of the chemical and bi
ological flocculating agents, isolation of EBF-producing mi cro organisms,
culture conditions, mechanisms of flocculation, the chemical structure of E
BFs, and the role of physicochemical factors in the flocculating activity.
