英文摘要A new flocculant-producing bacterium Paenibacillus polymyxa BY-28 was isolated from soil. The optimal culture media for flocculant production were 2% glucose, 0.3% KH2PO4, 0.1% bean cake powder, 0.05% CaCl2 and 0.05% (w/v) MgSO4.7H(2)O. Optimal culture temperature was 30degreesC and pH was 6-8. Flocculants produced under optimal conditions efficiently aggregated various organic and inorganic suspensions in simulated water as well as in wastewater by addition of bivalent and trivalent cations Ca2+. From Zeta-potential measurement, the dominant role of microbial flocculant in the flocculation process is based on the bridging mechanism, and the role of CaCl2 is to decrease the negative electrical charge of the Kaolin clay particles.
