STUDY ON EFFICIENT BIOFLOCCULANT BY A KLEBSIELLA MOBILIS

A strain was screened from soil, identified as Klebsiella mobilis.It produces bioflocculant from dairy wastewater, which is thought of as a cheaper medium. The test results of bioflocculant activity for KLE-1 show that the bioflocculant, which is of polysaccharide bioflocculant, has high efficient of Kaolin clay.Bioflocculant activity can be apparently improved when using calcium ion as the flocculant-aid. There is no question that bridging operates the particles of the suspension by the way of infrared spectrum and zeta-potential measurements.
