ABSTRACT
This paper mainly discussed a bacterial stain with high flocculating activity isolated from cantaloupe juice .The strain was named Bacillus sp.B_(53) based on colony morphology, physiological and biochemistry experiments. The new flocculant was purified and shown to be a homopolymer of glutamic acid by HLPC analysis and thin layer chromatography, and presumed to be Poly ?-glutamic acid(?-PGA). ?-PGA 12.48g/L was achieved in shake flask. The purified material showed a absorption peak at 212nm, and was only composed of L-Glu. The MW could be detected through SDS-PAGE, and its MW was about a molecular mass between 440kD with 669kD. This bioflocculant efficiently flocculated various organic and inorganic suspensions. It's flocculanting effect on kaolin and ([BF]Ca(OH)_2[BFQ]) was superior to others.
